A substance that readily burns when it comes into contact with a flame has the chemical property of reactivity. The answer is letter C. Reactivity is a chemical property of a substance. According to EPA regulations, it is normally unstable and readily undergoes violent change without detonating. it can explode or violently react when exposed to water, when heated, or under STP.

Find the pOH of a solution made by dissolving 10.4g of HCl in a 500mL solution of water
shutvik [7]

The pOH of a solution : 13.756

<h3>Further explanation</h3>

Mass HCl=10.4 g

mol HCl (MW=36.5 g/mol) :

\tt mol=\dfrac{mass}{MW}=\dfrac{10.4}{36.5}=0.285

Volume of HCl = 500 ml = 0.5 L

\tt M=\dfrac{n}{V}\\\\M=\dfrac{0.285}{0.5}=0.57~M

HCl ⇒ H⁺ + Cl⁻

[H⁺]=[HCl]=0.57 M

pH= - log[H⁺]

pH=-log[0.57]=0.244

pH+pOH=14

pOH=14-0.244

pOH=13.756

During the titration of a weak acid and a strong base, you would expect the ph at the endpoint of titration to be ____.
riadik2000 [5.3K]

Answer is: b. more than 7.

The endpoint is the point at which the indicator changes colour in a colourimetric titration and that is point when titration must stop.

For example, basic salt sodium acetate CH₃COONa is formed from the reaction between weak acid (in this example acetic acid CH₃COOH) and strong base (in this example sodium acetate NaOH).

Balanced chemical reaction of acetic acid and sodium hydroxide:

CH₃COOH(aq) + NaOH(aq) → CH₃COONa(aq) + H₂O(l).

Neutralization is is reaction in which an acid (in this example vinegar or acetic acid CH₃COOH) and a base react quantitatively with each other.
