The amount of protons in the atoms' nucleus, of this substance, is 33. Since there are 33 electrons in a neutral atom, arsenic-neutral atoms, which have an equal amount of protons and electrons, are neutral.
When an atom is free of all charges, it is considered to be neutral. Ions are named when an atom has a charge on it. As a result, an atom is said to be neutral if it is in its initial state, which is one in which an electron has neither lost nor gained.
Any other atom may contain the same subatomic species that a neutral atom does. Electrons, protons, and neutrons make up the subatomic species. The distinction is that neutral atom have the same number of positive species as negative species, which cancels out all charges. A neutral atom thus has the same number of protons and electrons as a charged atom.

2. 2CO(g) ⇌ C(s) + CO2(g)
3. N2O4(g) ⇌ 2NO2(g)
1. CO(g) + H₂O(g) ⇌ CO₂(g) + H₂(g), the number of moles of products remains the same.
2. 2CO(g) ⇌ C(s) + CO₂(g), the number of moles of products increase.
3. N₂O₄(g) ⇌ 2NO₂(g), the number of moles of products decrease.
What is equilibrium?Any change in the equilibrium can be studied on the basis of Le-Chatelier's principle. This principle can describe that for any change in the variables of the reaction, the equilibrium shift in the direction to minimize the effect of that change.
CO(g) + H₂O(g) ⇌ CO₂(g) + H₂(g)
On increasing the pressure, the equilibrium shift in direction where decrease in pressure is occurring, the reaction will shift in no direction because the number of gaseous moles is the same on both sides. Therefore, no increase in the number of moles of products.
2CO(g) ⇌ C(s) + CO₂(g)
On increasing the pressure, the reaction will shift in a forward direction because the number of gaseous moles is less on the product sides. Therefore, increase in the number of moles of products.
N₂O₄(g) ⇌ 2NO₂(g)
On increasing the pressure, the reaction will shift in a backward direction because the number of gaseous moles is less on reactant side both sides. Therefore, decrease in the number of moles of products.

Answer:
A
Explanation:
Which of the following physical properties would be expected to decrease as intermolecular forces increase? A. critical temperature B. boiling point C. vapor pressure
D. heat of vaporization E. none of these properties would decrease
On decreasing the intermolecular forces, the critical temperature increases. So, option A is correct.
Critical temperature is the temperature above which a gas cannot be get liquified. Now, by this hypothesis we mean that the molecules of the gas come closer to each other and thus molecules attract towards each other. Intermolecular forces hold the molecules to each other . They are responsible for keeping a solid a solid and a liquid a liquid. With weak IMF the material remains a gas, like oxygen and nitrogen in our air. The greater force that is applied, the more energy is needed to separate the molecules.
So, more the magnitude of intermolecular force more will be the tendency of a gas to get easily liquify and the critical temperature will substantially get increased

After first half life is after 12.5 hours, concentration is reduced to 0.8105 M.
Concentration of A after 12.5 hours is 0.8105 M
After second half life ( ie 25 hours = 2*12.5 h), concentration of A is reduced to 0.4053 M
After 3rd half life (ie 37.5 hours = 3*12.5 hours) , concentration of A is reduced to 0.2026 M ( Half of 0.4053 M)

A student determines that a gas has a density of 1.948gL at a pressure of 748.1 mmHg and a temperature of 22.9 C. What is molar mass of gas?
Answer: 48.0 g/mol
Explanation:
The formula for molar mass of a gas is M=(RTd)/P, where R is the gas constant, d is density, T is temperature in kelvin, and P is pressure in atm.
First, we must convert mmHg to atm, 748.1/760= 0.9843 atm.
Then, we must convert C to K, 22.9+293=295.9K.
Lastly, we can plug in our values:
M=(1.948x0.082x295.9)/0.9843=48.0g/mol
