Since you didn't include the options, I will answer the question as well as I can: the one factor I would be considering is whether the journal is known to be biased, for example whether it's a peer-reviewed journal ( those are less biased) or whether they journal is paid by some interest group.

Otherwise I would look at whether the data is reliable, for example whether the author cites the sources for their data

Calculate the enthalpy for the following reaction. During the reaction, the temperature changes from 42.5 C to 37 C. The specifi

Dahasolnce [82]

Answer:

$q = 0.810$ Kj/mol

Its an endothermic reaction

Explanation:

Enthalpy can be evaluated by using following formula -

$q = m * c* \delta T$

where

q is the enthalpy or change in internal energy

m is the mass in kg

c is the specific heat

and $\delta T$ is the change in temperature

Mass of HCl is equal to $36.46$ g/mol

Mass of HCl is equal to $0.03646$ Kg/mol

Substituting the given values in above equation, we get-

$q = 0.03646 * 4.04 * (42.5 - 37)\\q = 0.03646 * 4.04 * 5.5 \\$

$q = 0.810$ Kj/mol

Enthalpy is positive thus it is an endothermic reaction

At a certain temperature, 0.760 mol SO3 is placed in a 1.50 L container. 2SO3(g) = 2SO2(g) + O2(g)At equilibrium, 0.130 mol O2 i

olganol [36]

Answer:

$K_c=0.0867$

Explanation:

Moles of SO₃ = 0.760 mol

Volume = 1.50 L

$Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}$

$Molarity=\frac{0.760}{1.50\ L}$

[SO₃] = 0.5067 M

Considering the ICE table for the equilibrium as:

$\begin{matrix} & 2SO_3_{(g)} & \rightleftharpoons & 2SO_2_{(g)} & + & O_2_{(g)}\\At\ time, t = 0 & 0.5067 &&0&&0 \\ At\ time, t=t_{eq} & -2x &&2x&&x \\----------------&-----&-&-----&-&-----\\Concentration\ at\ equilibrium:- &0.5067-2x&&2x&&x\end{matrix}$
