1. Which of the following is true regarding a Dynamic Equilibrium? a) it may occur in both open and closed systems b) the forward reaction is only occurring c) the concentrations found at equilibrium are different if a system approaches equilibrium from different directions d) the concentration of reactants and products remains constant 2. The type of dynamic equilibrium between different physical states of a pure substance in a closed system is called: a) Solubility Equilibrium b) Phase Equilibrium c) Chemical Equilibrium d) Homogeneous Equilibrium

D) the concentration of reactants and products remains constant.

Explanation:

1. Which of the following is true regarding a Dynamic Equilibrium?

A) it may occur in both open and closed systems. FALSE. It can only occur in closed systems. Otherwise, gases would leave the recipient and it would be impossible to reach the equilibrium.

B) the forward reaction is only occurring. FALSE. The forward reaction and the reverse reaction occur at the same rate.

C) the concentrations found at equilibrium are different if a system approaches equilibrium from different directions. FALSE. The equilibrium is the same regardless of the direction from which it comes.

D) the concentration of reactants and products remains constant. TRUE.

passed in september 1935, these laws are known as nuremberg laws.   they forbid jews from marrying but not directly forced them to divorce aryans. what is most noticeable is the fact that the jews were defranchised, meaning by this that they were not expected to have any civil rights, including the right to vote. the right answer is deprived of the right to vote.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
