Answer:
1 : 2
Explanation:
From the question given, we obtained the following information:
T1 = 287°C = 287 +273 = 560K
T1 = 587°C = 587 +273 =860K
V1 = V
V2 =?
V1 /T1 = V2 /T2
V/560 = V2/860
Cross multiply
V2 x 560 = 860 x V
Divide both side by 560
V2 = (860 x V) / 560
V2 = 1.54V = 2V
The ratio of initial to final volume =
V1 : V2
= V : 2V
= 1 : 2
Answer:
four moles could be produced
Explanation:
The computation of the number of moles for producing from the dissolution is shown below:
Given that
It could be disassociated as
Therefore ions and 1 could be generated
And from 1 mole of ,
= 3 + 1
= 4 moles
Therefore four moles could be produced
By considering the above calculation we can easily determine the number of moles
Because the compounds<span> that make up </span>air<span> e.g. oxygen (o2), Carbon dioxide (co2) and water is a compound because the composition of water is fixed, H2 and 02 react to form water. </span>
The reactants are higher in energy than the products
