Answer:
Well they didn't transfer any energy when they weren’t touching and it did t produce any energy if it didn’t move. Since they are on top of each other they are causing momentum on each other creating kinetic energy
Explanation:
The question is: 10 g of carbonic acid H2CO3 are dissolved in 150 g of water. Determine the% m / m concentration of that solution?
Answer: The% m / m concentration of that solution is 6.66%.
Explanation:
Given: Mass of solute = 10 g
Mass of solvent = 150 g
Formula used to calculate the %m/m is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that the% m / m concentration of that solution is 6.66%.
Reactant + reactant = product
C + O2 = CO2
carbon dioxide is what's being made is product
Answer:
Avogrado's number
Explanation:
It's unniversal measure of moles
p [OH-] = -log[OH-]= -log ( 1x10^-11M) = 11
we know that
p[OH-] + p[H+] = 14
so p[H+] = 14- p[OH-] = 14- 11 = 3
pH = 3, answer
