Answer:
23.84g CH30H
32.81g H2O
Explanation:
We will be using the definition of mole fraction to determine the relationship between the number of moles of methanol,
CH3OH , and the number of moles of water.
But mole fraction gives the ratio between the number of moles of a component i of a solution to the total number of moles present in that solution.

Answer:
When the speed of an object remains the same for a certain distance of time
Explanation:
Answer:
Solid, liquid or gas. So there is movement no matter the state. The key variable is density. The higher the density the less movement. In solids the motion can be so small it's very hard to measure. Gas on the other hand is easy the motion being large. Bear in mind temperature plays a big role. Higher temps bring faster motion. Finally the pressure of the gas brings about less motion the higher it is as the molecules are closer together & can't move as much.
Explanation:
1 molecule of NO2 included N atom and 2 oxygen atoms, so a total of 3 atoms per molecule.
1.3 x 10^22 times 3 = 3.9 x 10^22 atoms
Answer: HA + H2O ⇌ H3O+ + H- (option #4)
Explanation: Since the acid is weak you have to use a ⇌ (equilibrium) sign. Equilibrium is denoted in a chemical equation by the ⇌ symbol. Also, when any acid dissolves into water, it produces hydronium (H3O+ or H+). Therefore, the fourth chemical reaction is your answer.
