It should be option (A) because conduction is the transfer of heat energy from one place to another by vibrations/motion of the molecules. I hoped I helped.
Answer:
- Initial: forward rate > reverse rate
- Equilibrium: forward rate = reverse rate
Explanation:
2NO₂(g) → N₂O₄(g) Kc=4.7
The definition of <em>equilibrium</em> is when the forward rate and the reverse rate are <em>equal</em>.
Because in the initial state there's only NO₂, there's no possibility for the reverse reaction (from N₂O₄ to NO₂). Thus the forward rate will be larger than the reverse rate.
KHP is an acronym which stands for potassium hydrogen phthalate. It is an acidic salt which is white crystalline powder at room temperature. When in solution it is colorless. It has a chemical formula of C8H5KO4. Molar mass of a compound is the sum of the masses of all the atoms involved in the structure of the compound. So, we need the atomic masses of the elements involved. We do as follows
C = 12.01 g/mol x 8 = 96.02 g/mol
H = 1.01 g/mol x 5 = 5.05 g/mol
K = 39.10 g/mol x 1 = 39.10 g/mol
O = 16 g/mol x 4 = 64 g/mol
Adding, we will have 204.17 g/mol. This would be the molar mass of KHP.
Answer:
10.
Explanation:
Hello,
In this case, for the given reaction:
By knowing the law of conservation of mass must be respected, the following coefficients do balance the chemical equation:
So the sum of all the coefficients is 10.
