The entropy of the reaction can be calculated alike the enthalpy of the reaction which is equal to the difference between the summation of entropies of the products multiplied by their corresponding stoich coeff. and the summation of the entropies of the reactants multiplied by their corresponding stoich coeff. In this case, the answer is -146.8 J / mol K
Answer:
Which is the ph of a solution in which the concentration of hydroxide ion is greater than the concentration of hydrogen ion?
An acidic solution is one in which the hydrogen ion concentration is greater than the hydroxide ion concentration; in other words, the hydrogen ion concentration is greater than 1 X 10-7 M, and the hydroxide ion concentration is less than 1 X 10-7 M. In terms of pH, an acidic solution has a pH less than 7
Explanation:
Answer:
Nothing is happening.
Explanation:
As written, nothing is going on. H2+O2+H2O represents a mixture of H2, O2, and H2O. We aren't even given the states, so they may all be gases, liquids/solids, or dissolved gases in a liquid (water).
If we had H2+O2 → H2O, we could say that hydrogen and oxygen are combining to form H2O, water. We should note, however, that the chemical equation is not balanced. There are two oxygen atoms on the reactant side, but only one on the product side. A balanced equation would read:
2H2 + O2 → 2H2O
It would be nice to indicate the physical states, such as:
2H2(g) + O2(g) → 2H2O(l)
Two gases, oxygen and hydrogen, combine to form liquid water.
Also missing from this equation is the energy that may be consumed, or released in this reaction. It would be nice to know, for example, that this reaction releases a lot of energy. Otherwise, we might wind up in the local headlines.
ANSWER
The molar mass of carbon monoxide is 28g/mol or 2.8 x 10^1 g/mol
EXPLANATION
Given that
The chemical formula of carbon monoxide is CO
Note that, the unit mass of carbon is 12.01u and the unit mass of oxygen is 15.99u
Based on the atomic masses of the elements, we can now find the molar mass of CO
Therefore, the molar mass of carbon monoxide is 28g/mol or 2.8 x 10^1 g/mol
