A) because spontaneous means in an instant
Answer : The standard enthalpy change for the combustion of CO(g) is, -283 kJ/mol
Explanation :
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
The combustion of
will be,

The intermediate balanced chemical reaction will be,
(1)

(2)

Now we are reversing reaction 1 and then adding both the equations, we get :
(1)

(2)

The expression for enthalpy change for the reaction will be,



Therefore, the standard enthalpy change for the combustion of CO(g) is, -283 kJ/mol
Answer:
Spiders and ground beetles.
Why is Anthony so mean? Don't hurt the beetles!
Answer:
1386g
Explanation:
Solubility of a solute is the ability of the solute to mix into a liquid (the solvent). It measures the highest amount of substance mixed into a liquid solvent while they are both at equal amounts.
if 14g dissolved in 100cm3
the amount that will dissolve in 1000cm3 = 14 x 1000/ 100
=1400g
To form a saturated solution, 1400 - 14 = 1386g must be added.
