Answer:

Option C It has the same concentration of hydronium and hydroxide ions is correct.

Explanation:

A neutral solution will have pH=7

and the concentration of hydronium ions and hydroixde ions is the same.

So, Option C It has the same concentration of hydronium and hydroxide ions

is correct.

Answer: Option (c) is the correct answer.

Explanation:

A solution whose pH is less than 7 is known as an acidic solution. In this solution, concentration of hydrogen ions is more than hydroxide ions.

Whereas a solution whose pH is more than 7 is known as a basic solution. In this solution, concentration of hydroxide ions is more than hydrogen ions.

On the other hand, when pH of a solution is equal to 7 then the solution will be known as neutral solution. That is, the concentration of both hydrogen and hydroxide ions is same in a neutral solution.

Thus, we can conclude that the statement it has the same concentration of hydronium and hydroxide ions, is true about a neutral solution.

What is the pH of this solution?
Vesnalui [34]

Answer:

pH = 11.216.

Explanation:

Hello there!

In this case, according to the ionization of ammonia in aqueous solution:

NH_3+H_2O\rightleftharpoons NH_4^++OH^-

We can set up its equilibrium expression in terms of x as the reaction extent equal to the concentration of each product at equilibrium:

Kb=\frac{[NH_4^+][OH^-]}{[NH_3]} \\\\1.80x10^{-5}=\frac{x*x}{0.150-x}

However, since Kb<<<1 we can neglect the x on bottom and easily compute it via:

1.80x10^{-5}=\frac{x*x}{0.150}\\\\x=\sqrt{1.80x10^{-5}*0.150}=1.643x10^{-3}M

Which is also:

[OH^-]=1.643x10^{-3}M

Thereafter we can compute the pOH first:

pOH=-log(1.643x10^{-3}M)\\\\pOH=2.784

Finally, the pH turns out:

pH=14-2.784\\\\pH=11.216

Regards!

When excess dilute hydrochloric acid was added to sodium sulphite 960 of sulphuric (iv) oxide was produced. calculate the mass o
irakobra [83]

The mass of sodium sulfite that was used will be 1,890 grams.

<h3>Stoichiometric problems</h3>

First, the equation of the reaction:

NaSO_3 + 2HCl --- > NaCl_2 + H_2O + SO_2

The mole ratio of SO2 produced and sodium sulfite that reacted is 1:1.

Mole of 960 grams SO2 = 960/64 = 15 moles

Equivalent mole of sodium sulfite that reacted = 15 moles

Mass of 15 moles sodium sulfite = 15 x 126 = 1,890 grams

Why does surface area of a reactant influence the rate of the reaction?
telo118 [61]

because it can influence how frequently and sufficiently the particles collide depending on the space it has to do so, for example a large surface area would be have a slower rate of reaction and a lower temperature. (the rate of reaction in terms of concentration, it is diffused from high to low)
