Answer:
Explanation:
Hello,
In this case, for the given dissociation reaction, we can compute the enthalpy of reaction considering the enthalpy of formation of each involved species (products minus reactants):
Next, the entropy of reaction considering the standard entropy for each involved species (products minus reactants):
Next, since the Gibbs free energy of reaction is computed in terms of both the enthalpy and entropy of reaction at the given temperature (298.15 K), we finally obtain (two significant figures):
Best regards.
Given that the liquid conserves the volume, when it is changed from one container to another, the kinetic molecular theory predicts no change in the velocity of the molecules, which means that the temperature will not change.
Answer:
allows for you to account for only the weight of the substance being measured and not the vessel it’s being measured in.
Explanation:
What does it mean to tare a balance and why do you think it is important to complete this before you begin measuring mass? Explanation: The term tare is used when weighing chemicals on a balance, using the tare button allows for you to account for only the weight of the substance being measured and not the vessel it’s being measured in.
They did not repeat their tests multiple times.
Reason being is using the same stopwatch doesn’t matter and changing the reactants won’t help, and you without a doubt need more than one person collecting the data so,
They did not repeat their tests multiple times is the answer.
To rank the effective nuclear charge Z* experienced by a valence electrons of a set of atoms that belong to a same period, you only need to apply the rule of trend: it increases as you move from left to right in the period.
So, lets do it for these atoms: P, Al, Si, Cl
The belong to a same period and the order is Al, Si, P, Cl (just see a periodic table). So the rank is Al < Si < P < Cl
Now, lets do it for these atoms:, Be, Ne, O, C
They belong to the second period. The order is Be, C, O, Ne
So, the rank is Be < C < O < Ne.
