A higher concentration of reactants leads to more collisions per unit time and leads to an increasing reaction rate. Changing the pressure of gaseous reactants is, in effect, changing their concentration. The increased number of collisions caused by a higher pressure generally increases the reaction rate.
You don't have to do this first part, but I think it's important to know if something is ionic, sometimes you get trick questions on exams.
Na has an electronegativity of 0.93.
Cl has an electronegativity of 3.16.
--------- There is a difference of, 2.23
When the electronegativity difference is greater than 1.5, the compound is ionic.
NaCl is an ionic compound, so when it dissolves in a solvent, it separates into two.
Steps to solve:1. There are 6.02 x 10²³ molecules in one mole
2. There are 13.54 moles in our sample
3. We must convert moles to molecules by multiplying.
4. After the number of molecules is obtained, you must multiply that number by 2 to obtain the number of ions, because NaCl is ionic.
Hope this helps!
Answer:
713mmHg
Explanation:
By using Dalton's law of partial pressure, the pressure outside the gas container is equal to the pressure inside it and this pressure equals the sum of the pressures of water and the gas.
i.e, P(total) = P(gas) + P(water)
P(gas) = P(total) - P(water)
P(gas) = 735 - 22
P(gas) = 713mmHg
Mass is not weight. Weight determines how much gravity is pulling you down. Weight changes (for example, if you went to the moon, you would be a lot lighter). However, your mass never changes. I would say false since mass isn't even the same as weight. :/
