The answer to this question would be: too low
Molar mass would be determined by the number of mol and the mass of the object. Mass wouldn't be influenced by the temperature, but number of mol is. Using ideal gas formula of PV=nRT you can conlude that the amount of mol(n) is inversely related to the temperature (T).
If the temperature is higher than it supposed to be, then the amount of mol would be lower than it supposed to be.
It’s some apps that come in handy for this sorry if I didn’t help
Answer:
Not sure were to start....
Explanation:
Answer:
An atom becomes an Ion (a) if it gains one or more electron(s) or (b) if it loses one or more electron(s). When it gains electrons it becomes negatively charged and is called an anion. When it loses electron(s) it becomes positively charged and is called a cation.

hope i helped let me know if it did!!
Answer:
Explanation:
The question must be restated because you can calculate ΔH₂ from the other reactions only if you know the global ΔH, ΔH₁, and ΔH₃.
As stated by Hess’s law, the overall change in the enthalpy, ΔH, of a reaction does not depend of the path followed. Thus, when you have a series of reactions, the net change from the first reaction to the last reaction is equal to the sum of the ΔH values for the individdual reactions:
If you name ΔH₄, the overal change in the enthalpy to convert 1 to 4, but ΔH₁, ΔH₂, and ΔH₃ are the changes of the intermediate reactions that transform 1 in 2, 2 in 3, and 3 in 4, respectively, then, you can write, accordingly to Hess's law, you can write:
Then, assuming you know ΔH₄, ΔH₁, and ΔH₃, you can calculate ΔH₂ clearing from the previous equation:
- ΔH₂ = ΔH₄ - (ΔH₁ + ΔH₃) ← answer
