Answer:
1 mole
Explanation:
Data obtained from the question include:
P (pressure) = 750 torr
But 760torr = 1atm
750 torr = 750/760 = 0.99atm
V (volume) = 25L
T (temperature) = 300K
R (gas constant) = 0.082atm.L/Kmol
n (number of mole) =?
Using the ideal gas equation PV = nRT, we can easily find the number of mole as illustrated below:
PV = nRT
n = PV /RT
n = 0.99 x 25 / 0.082 x 300k
n = 1 mole
Therefore, the number of mole of the gas is 1 mole
<span>All collisions between atoms or molecules are perfectly elastic and are not the result of any attractive forces is the best answer in my opinion since ideal gas particles have elastic collisions and do not interact with each other.</span>
Answer:
the changing tempure in rocks causing it to back apart
Answer: In the reaction:
a) The reactants are: P
b) The products are: M and N
Explanation:
The given reaction equation is as follows.
Reactants are the species present on the left side on an arrow in a chemical reaction equation.
On the other hand, products are the species which are present on the right side of an arrow in a chemical reaction equation.
Hence, in the given reaction equation P is the reactant. Whereas M and N are the products.
Thus, we can conclude that in the reaction:
a) The reactants are: P
b) The products are: M and N
