A solution means that you're trying to solve (or deal) with a situation.
For example, if you're having trouble trying to solve a math problem, that means that you're trying to figure out that problem.
Answer:
22.8 mmHg
Explanation:
According to Dalton's law of partial pressures, the total pressure of a mixture of gases is obtained as the sum of the partial pressures if all the individual gases present in the mixture.
Since the total pressure of gases in the mixture is 0.998 atm, the partial pressure of carbon dioxide is;
PCO2 = [Ptotal - (PO2+ PN2)]
Hence;
PCO2 = [0.998 - (0.198 + 0.770)]
PCO2 = 0.03
Since
1 atm = 760 mmHg
0.03 atm = 0.03 × 760 /1
=22.8 mmHg
Answer:
Particles can only react when they collide. If you heat a substance, the particles move faster and so collide more frequently. That will speed up the rate of reaction. ... The rate of reaction will probably have doubled for that increase in temperature - in other words, an increase of about 100%.
HOPES IT HELPS
That statement is true
it was easy to organize 'all' the elements in a group of threes because back then they only knew about 15 - 20 elements
hope this helps
