which sample displayed the lower ph? di water or boiled di water

Answers

Answer 1

Boiled deionized (DI) water would typically display a lower pH compared to regular DI water.

Boiling deionized water can lead to the removal of dissolved gases, such as carbon dioxide, which can contribute to the formation of carbonic acid and result in a slightly lower pH. The removal of dissolved gases through boiling can make the water less acidic overall.

However, it is important to note that the pH of both regular DI water and boiled DI water should be very close to neutral, around 7, as pure water is considered neutral. The difference in pH between regular DI water and boiled DI water would be minimal, with boiled DI water potentially showing a slightly lower pH due to the removal of dissolved gases.

write the complete electron configuration for bromine using the periodic table

Answers

Bromine is a non-metal element with the chemical symbol Br and atomic number 35. To write the complete electron configuration of bromine, we first need to determine the number of electrons in its neutral state. Since bromine has an atomic number of 35, it means that it has 35 electrons in its neutral state.

The electron configuration of bromine can be written by using the Aufbau principle, which states that electrons fill the lowest energy level orbitals first before moving to higher energy levels. The electron configuration for bromine can be written as follows:

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5

The first number represents the principal quantum number, which determines the energy level of the electrons. The letters represent the subshells, where s, p, d, and f are the different subshells. The superscript numbers represent the number of electrons in each subshell.

In the case of bromine, the first two electrons are in the 1s orbital, followed by two electrons in the 2s orbital and six electrons in the 2p orbital. After that, there are two electrons in the 3s orbital and six electrons in the 3p orbital. The remaining ten electrons are in the 4s, 3d, and 4p orbitals, with five electrons in the 4p orbital.

Thus, the complete electron configuration for bromine using the periodic table is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5.

Two firms, A and B, are located at points 0 and 1 respectively. We denote by p; the price of firm i A, B. A consumer located at point x [0, 1] obtains utility U(x) = u - PA - tx if he consumes from firm A, and UB(x)=u-PB-t(1-x) if he consumes from firm B. In the following, we assume that the gross utility u is sufficiently high, so that the market will be covered and all consumers will get positive utility in equilibrium.
