Answer:
5.97 mol
Explanation:
To find the number of moles when given the mass of a substance, we divide the mass of the sample by its molar mass.
so, we get,
nN203 = 454 g / 76.01 g /mol
= 5.97 mol
it would be species in this case
According to the cooling curve given above, at temperature 275K, the phases that will be observed is LIQUID AND SOLID.
The flat points on the graph represent the points where phase changes are taking place.The beginning of the first flat point represent the point where the gas become liquid, the extreme end of this point indicate the point where the liquid has started turning to liquid and that is the point of 275K. Thus at that point both phases are present.
Answer:
It is the stove
Explanation: I know because I learned this last year
H₂ + CO₂ ⇄ CO + H₂O
1 mol H₂ - 1 mol H₂O
x mol H₂ - 30.6 mol H₂O
x=30.6*1/1=30.6 mol (<span>theoretically)</span>
