Hello, Lindaparker, a spit could form from a rocky headland where prevailing winds would
blow at an angle to the rocky headland, gradually depositing sand and
shingle at that place. A spit is a permanent land form resulting
from marine deposition and wind deposition. It is usually a long and
narrow accumulation of sand or shingle with one joined to the land and
the other end projecting at a narrow angle out into the sea. Salt marshes sometimes form on the sheltered side of a spit.
Answer:
Kindly check the explanation section.
Explanation:
From the description given in the question above, that is '' H subscript f to the power of degree of the reaction" we have that the description matches what is known as the heat of formation of the reaction, ∆fH° where the 'f' is a subscript.
In order to determine the heat of formation of any of the species in the reaction, the heat of formation of the other species must be known and the value for the heat of reaction, ∆H(rxn) must also be known. Thus, heat of formation can be calculated by using the formula below;
∆H(rxn) = ∆fH°( products) - ∆fH°(reactants).
That is the heat of formation of products minus the heat of formation of the reaction g specie(s).
Say heat of formation for the species is known as N(g) = 472.435kj/mol, O(g) = 0kj/mol and NO = unknown, ∆H°(rxn) = −382.185 kj/mol.
−382.185 = x - 472.435kj/mol = 90.25 kJ/mol
<span>CH4+2O2———> CO2 +2H2O
M(CH4)=16.0 g/mol
</span>30g CH4*1mol/16.0 g - mol of CH4
30g CH4*(1mol/16.0 g)*(2 mol H2O/1 mol CH4) =15 mol H2O
30g CH4*(1mol/16.0 g)*(2 mol H2O/1 mol CH4)*22.4L/1mol=84 L H2O as gas, but at STP water should be liquid,so
15 mol H2O*18g H2O/1 mol=270g of H2O
270g*1ml/1g= 270 ml =0.27 L of liquid water, in reality it should be like this,
but I do not know what people who created this problem wanted H2O as liquid or as gas
