Answer:B
Explanation:
the particles in a gas are more far apart and have more kinetic energy than liquid because they are more close together and have less kinetic energy than gas.
Answer:
Partial pressure of methane: 1.18 atm
Partial pressure of ethane: 1.45 atm
Partial pressure of propane: 2.35 atm
Explanation:
Let the total moles of gases in a container be n.
Total pressure of the gases in a container =P = 5.0 atm
Temperature of the gases in a container =T = 23°C = 296.15 K
Volume of the container = V = 10.0 L
(Ideal gas equation)
Moles of methane gas =
Moles of ethane gas =
Moles of propane gas =
Partial pressure of all the gases can be calculated by using Raoult's law:
= partial pressure of 'i' component.
= mole fraction of 'i' component in mixture
P = total pressure of the mixture
Partial pressure of methane:
Partial pressure of ethane:
Partial pressure of propane:
Answer:
Ionic compounds, such as sodium chloride, are also highly soluble in water. Because water molecules are polar, they interact with the sodium and chloride ions. In general, polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes.
Explanation:
The 3 (THREE) particles of the atoms are:
_______________________________________________
protons, neutrons, and electrons .
__________________________________________________________
Answer:
a.
1. NO2(g): Reactant.
2. CO(g): Reactant.
3. NO3(g): Intermediate.
4. CO2(g): Product.
5. NO(g): Product.
b. See attached picture.
Explanation:
Hello,
a. In this case, given the reactions, we can identify each species as:
1. NO2(g): Reactant because it remains at the left side in the overall reaction.
2. CO(g): Reactant because it remains at the left side in the overall reaction.
3. NO3(g): Intermediate because it is a product in the step 1 and a reactant in step 2, for that reason it is not present in the overall reaction.
4. CO2(g): Product because it remains at the right side in the overall reaction.
5. NO(g): Product because it remains at the right side in the overall reaction.
b. In this case, given that the first step is slow and endothermic, it has a high activation energy and the products will have more energy than the reactants, for that reason the final energy is above the initial point. Moreover, since the second step is fast and exothermic, it has a low activation energy and the products will have less energy than the reactants, for that reason, the reaction coordinate diagram is shown on the attached file.
Regards.
