I think the correct answer from the choices listed above is option B. <span>24 mL of Mg burn in 32 mL O2 to produce 56 mL of MgO </span>does not show the law of conservation of mass. Volumes cannot be added because there are volume effects when you add different substances. So, the reactants is not equal to the product.
Enthalpy heat of vaporization is the measurement of heat required to convert an amount of substance from the liquid to the gas phase.
<span>What
is the ph of an acetic acid solution if 10 drops are titrated with 70
drops of a 0.65 m koh solution? (ka for acetic acid = 1.8 x 10-5)?
[KOH] = 0.65 M
[OH] = 0.65 M
</span>Dilute your mom
<span>[OH]Dil= 0.65 M * 70/80 = 0.56875 M
pH = 5.4

Answer:
The system will change its concentration to shift to a new equilibrium position.
Explanation:
For example in the Haber Process
N2 + 3H2 ⇄ 2NH3
If the pressure is increased the process will move to the right - to have more NH3 and less of the nitrogen and hydrogen.
