What are the best units for a scientist to measure the distance between cities?
A. miles
B.inches
C.meters
D.kilometers

Answers

Answer: A and D

Explanation: Miles and Kilometers are the best units when measuring distances between cities, this is because both units will in most cases give a reasonable representation of the distance being measured by giving an output which isn't too large or extremely small. Feets and inches are usually adopted when measuring length of objects which in most cases are small and average only a few meters. Meters are also used for measuring short and medium distances. However, representing distances between two cities in terms of inches or feets will usually give extremely large values. Hence, the need for a fairly larger unit in miles or kilometers.

gold is heavier than aluminium if we put a 100 gram biscuit of gold in water taken in a measuring cylinder or we put a 100 gram aluminium bar in the measuring cylinder will the rise in the level of the water be same or different in the two cases give reason​

Answers

Answer:

The level of the water will be higher for 100g Al because occupy more space than gold.

Explanation:

To understand this problem, we must know Archimedes' principle:

"A body that is submerged in a fluid produce a bouyant force equal to the weight of the fluid that the body displaces". The volume of the body is equal to the volume displaced in the liquid.

Now, as gold is heavier than aluminium, 100g of Al have more volume than 100g of gold, than means:

The level of the water will be higher for 100g Al because occupy more space than gold.

B: Particles move faster in the gaseous state than in the liquid state.

C: The carbon atoms in gaseous methane are further apart than those in solid diamond.

D: There is a large decrease in the volume of a solid metal when pressure is applied to it.

Answers

Answer:

D

Explanation:

If we put pressure on a solid or a liquid, there is essentially no change in volume.

Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Therefore, the incorrect statement is option D that is there is a large decrease in the volume of a solid metal when pressure is applied to it.

What is matter?

Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.

Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter. When we apply pressure on solid, then there is no change in volume of the solid matter.

Therefore, the incorrect statement is option D that is there is a large decrease in the volume of a solid metal when pressure is applied to it.

A sample of marble has a volume of 6 cm3 and a density of 2.76 g/cm3. What is its mass?

Answers

Answer:

16.56g

Explanation:

6*2.76=16.56...

Answer:

16.56 grams

Explanation:

The density can be found using the following formula:

[tex]d=\frac{m}{v}[/tex]

If we rearrange the formula for m, the mass, we should multiply both sides by v.

[tex]d*v=\frac{m}{v} *v[/tex]

[tex]d*v=m[/tex]

The mass can be found by multiplying the density and the volume. The density is 2.76 grams per cubic centimeter. The volume is 6 cubic centimeters.

[tex]d= 2.76 g/c^3\\v=6 cm^3[/tex]

Substitute the values into the formula.

[tex]m= d*v[/tex]

[tex]m= 2.76 g/cm^3 * 6 cm^3[/tex]

Multiply. When you multiply the 2 "cm^3" will cancel each other out.

[tex]m= 2.76 g* 6[/tex]

[tex]m= 16.56 g[/tex]

The mass of the marble is 16.56 grams.

What is the mass of a sample of iron that has had 300.0 j applied to it and heats up from 20.0 degrees Celsius to 40.0 degrees Celsius.. the specific heat of iron is 0.46j/gC

Answers

Answer:

The mass of a sample of iron that has had 300 J applied to it and heats up from 20 degrees Celsius to 40 degrees Celsius is 32.61 grams.

Explanation:

Calorimetry is the measurement and calculation of the measurement of heat changes exchanged by a body or a system produced in physical and chemical processes.

The sensible heat of a body is the amount of heat received or transferred by a body to produce a change in temperature but without a change in physical state.

The sensible heat in a constant pressure is calculated by:

Q = c * m * ΔT

where Q is the heat exchanged by a body of mass m, constituted by a substance of specific heat c, and where ΔT is the temperature variation (ΔT=Tfinal - Tinitial)

In this case:

Q= 300 Jc= 0.46 [tex]\frac{J}{g*C}[/tex]m= ?Tfinal= 40 CTinitial= 20 C

Replacing:

300 J= 0.46 [tex]\frac{J}{g*C}[/tex] * m* (40 - 20) C

Solving:

300 J= 0.46 [tex]\frac{J}{g*C}[/tex] * m* 20 C

[tex]m=\frac{300 J}{0.46 \frac{J}{g*C} * 20 C}[/tex]

m= 32.61 g

If 6.02*10^23 molecules of ammonia react with 12.04*10^23 molecules of hydrogen chloride, how many molecules are in the reaction vessel when the reaction is complete

Answers

Answer:

18.06 × 10²³ molecules

Explanation:

Add the two amounts of molecules together.

6.02 × 10²³  +  12.04 × 10²³  =  18.06 × 10²³

You will have 18.06 × 10²³ molecules in the vessel when the reaction is complete.  This is because of the Law of Conservation of Mass.  Mass is neither created nor destroyed in chemical reactions.  You will have the exact number of molecules in the reaction vessel as you did in the beginning.  The types of molecules may change, but the number will stay the same.

How much heat is absorbed by 20g granite boulder as energy from the sun causes its temperature to change from 10°C to 29°C? The specific heat capacity of granite is 0.79 J/gºC.

Answers

Given :

Mass of granite , m = 20 g .

Change in temperature , [tex]\Delta T=29-10=19^oC[/tex].

Specific heat capacity of granite , [tex]C=0.79\ J/g^oC[/tex] .

To Find :

The heat absorbed by granite .

Solution :

We know , heat absorb is given by :

[tex]\Delta H=mC\Delta T\\\\\Delta H=20\times 0.79 \times 19 \ J\\\\\Delta H=300.2\ J[/tex]

Therefore , heat absorb is 300.2 J .

Hence , this is the required solution .

Taking into account the definition of calorimetry, the heat absorbed is 300.2 J.

In first place, calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Sensible heat is the amount of heat exchanged by a body without affecting its molecular structure. If you don't change the molecular structure, you don't change the state of aggregation. Since the molecular structure does not change, a change in temperature is observed.

In other words, sensible heat is the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).

So, the equation that allows to calculate heat exchanges is:

Q = c× m× ΔT

where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case:

Q= ? c= 0.79[tex]\frac{J}{gC}[/tex] m= 20 g ΔT= Tfinal - Tinitial= 29 C - 10 C= 19 C

Replacing in the expression to calculate heat exchanges:

Q= 0.79[tex]\frac{J}{gC}[/tex]× 20 g× 19 C

Solving:

Q= 300.2 J

In summary, the heat absorbed is 300.2 J.

Answers

Answer:

The Argon ([tex]Ar[/tex]) has this electron configuration.

Explanation:

The question is wrong. The correct electron configuration is :

[tex]1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}[/tex]

The electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals.

The letters s,p,d and f are called the orbitals.

The numbers 1,2,3,4,5,6 and 7 are called the levels.

The maximum numbers of electrons that the s-orbital can hold is 2 electrons.

The maximum numbers of electrons that the p-orbital can hold is 6 electrons.

The maximum numbers of electrons that the d-orbital can hold is 10 electrons.

The maximum numbers of electrons that the f-orbital can hold is 14 electrons.

The order in which the orbitals are filled is :

1s-2s-2p-3s-3p-4s-3d-4p-5s-4d-5p-6s-4f-5d-6p-7s-5f-6d-7p-6f-7d-7f

To identify the electron configuration of an element we need to count and sum the exponents of its orbitals.

The electron configuration is :

[tex]1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}[/tex]

Has the following sum of exponents : [tex]2+2+6+2+6=18[/tex]

Therefore the total electrons of the element is 18 electrons.

The element that has 18 electrons is Argon ([tex]Ar[/tex])

You titrate 5.0 mL of HCl with 0.010 M NaOH. You find the end point of your titration occurs when 12.0 mL of NaOH has been added. What is the total volume of the solution at the end point of the titration

Answers

Answer:

The total volume of the solution at the end point of the titration is 17.0 mL

Explanation:

First we will write a balanced chemical equation for the reaction between HCl and NaOH.

HCl + NaOH    →    NaCl + H₂O

This means 1 mole of HCl will react with 1 mole of NaOH to give 1 mole of NaCl and 1 mole of H₂O

From the question,

Concentration of acid (HCl), [tex]C_{A}[/tex] = ??

Volume of acid (HCl), [tex]V_{A}[/tex] = 5.0 mL

Concentration pf base (NaOH), [tex]C_{B}[/tex] = 0.010 M

Volume of base (NaOH), [tex]V_{B}[/tex] = 12.0 mL

To determine the Concentration of acid, [tex]C_{A}[/tex]

From,

[tex]\frac{C_{A}V_{A} }{C_{B}V_{B} } = \frac{n_{A} }{n_{B} }[/tex]

Where [tex]n_{A}[/tex] is the mole ratio of acid

and [tex]n_{B}[/tex] is the mole ratio of base.

The concentration of the acid used can be determined from the above formula.

But, we are asked to find the total volume of the solution at the end point of the titration

The total volume of the solution will be the sum of the volume of HCl that reacted and volume of NaOH that reacted.

Hence, The total volume of the solution = [tex]V_{A} + V_{B}[/tex]

= 5.0 mL + 12.0 mL

= 17.0 mL

Hence, the total volume of the solution at the end point of the titration is 17.0 mL
