According to Dalton's Law of Partial pressures, the sum of the partial pressures of the individuals gas molecules that occupy a specific volume allows us to find the total pressure or find one of the partial pressures if the total pressure is known.
Partial pressure O2 = 632 - 124.3 - 461.9 = 45.8 mm Hg.
Answer:
The density of a potato is
Explanation:
Given that,
A potato that is too large to fit into a graduated cylinder.
Let us consider the mass of potato is M and volume of entire potato is V'.
The volume of water is V.
We know that,
Density :
The density is equal to the mass divided by volume.
In mathematically,
Where, m = mass
V = volume
We need to calculate the volume of potato
Using formula for volume
Where, V' = volume of potato
V''=Volume of combine water and potato
V = volume of water
We need to determine the density of a potato
Using formula of density
Put the value into the formula
Hence, The density of a potato is
D. A ll of the above. catalyst reduces the activation energy thereby making the reaction faster. an increase in temperature increases the kinetic energy and no of collisions making reaction faster for an endothermic reaction while decrease in temperature favors an exothermic reaction.
increase in concentration increases the molecules reacting so the reaction is faster and vice versa.
When Ag+ is combined with Na2CO3, the substances formed are Ag2CO3 and Na+. In this case, Ag performs single substitution over the element Na to form another set of substances. There are other types of reactions like double displacement, decomposition, etc.
