Answer: 1.5mol NH3
Explanation: 1N2+3H2= NH3
0.5 mol N2x 3NH3/1molN2= 0.5x3= 1.5mol NH3
The equation that can be used to calculate the volume is the ideal gas equation. This is only valid for use for gases. It is expressed as:
PV = nRT
where P is the pressure, V is the volume, n is the amount in moles of the gas, R is the universal gas constant and T is the temperature.
At constant pressure, the calculations are as follows:
T1 / V1 = T2 / V2
V2 = T2 x V1 / T1
V2 =373.15 x 5.0 / 323.15

are a number of ways to express concentration of a solution. This includes
molarity. Molarity is expressed as the number of moles of solute per volume of
the solution. So, we calculate as follows:
Molarity = 15.9 g BaCl2 ( 1 mol / 208.23 g ) / .375 L = 0.204 mol / L</span>
Volatility is the property of a liquid to change phase to gas. As you know, the molecular arrangement of liquids and gases differ in the inter-spaces. The molecules of the gas is more widely distributed so they have less intermolecular forces. Therefore, a liquid with high volatility has very low intermolecular forces. This means that they could be easily separated from each other to conform to the molecular arrangement of a gas.
The parameter that is well associated with volatility is vapor pressure. Think of it this way, when the vapor pressure equals the atmospheric pressure, the liquid boils and changes phase into gas. So, we can say that a liquid with high volatility exhibits high vapor pressure. In this case, it would only take less energy for the vapor pressure to reach the much higher atmospheric pressure.
Answer:
B) There is more water in the air because the rate of evaporation increases
Explanation:
As the temperatures rise across the globe, the rate of evaporation also increases, resulting in more water in the air. The reason for the increased evaporation is that the ice sheets and glaciers are melting, thus there's more liquid water. The more liquid water there is, the more evaporation there will be. As the evaporation increases, there will be an increase in the formation of clouds, thus there will be more precipitation around the world, gradually leading to warmer and wetter climate.
