Balanced chemical equation for reaction of hydronium ions with calcium carbonate will be as follows:
2H3O+ (aq) + CaCO3 (s) => Ca2+ (s) + 3H2O (l) + CO2 (g)
In this balanced chemical equation, acidic aqueous solution of hydronium ion (H3O+) reacts with calcium carbonate salt (CaCO3) resulting in the formation of calcium cation (Ca2+) an alkali, that results in neutralization of excessive acid. It also forms liquid water (H2O) along with liberation of carbon dioxide gas (CO2). All acids stronger than hydrogen carbonate, provide their calcium salts dissolved in water yielding carbon dioxide, because a bare hydrogen ion has no chance of surviving in water.
To balance this chemical equation, 2 molecules of hydronium ions react with 1 molecule of calcium carbonate resulting in formation of 1 molecule of calcium cation, 3 molecules of water and 1 molecule of carbon dioxide. The reaction proceeds at room temperature.

In the laboratory, a student dilutes 18. 9 ml of a 10. 0 m perchloric acid solution to a total volume of 250. 0 ml. what is the concentration of the diluted solution? concentration = m submit answer
The concentration of diluted solution is 0.756M.
From the question given above, the following data were obtained:
Volume of stock solution (V1) = 18.9 mL
Molarity of stock solution (M1) = 10 M
Volume of diluted solution (V2) = 250 mL
Molarity of diluted solution (M2) =?
We can obtain the molarity of the diluted solution by using the dilution formula as shown follow:
M1V1 = M2V2
10 × 18.9 = M2 ×250
189 = M2 × 250
Divide both side by 100
M2 = 189 / 250
M2 = 0.756 M
Therefore, the molarity of the diluted solution is 0.756 M.

Succinic acid is often found in high levels in tumors or biofluids surrounding tumors. it is a weak acid with a pka of 4. 21. what is the ph of a 0. 250 m solution of succinic acid?
The pH of a 0.250m solution of succinic acid is 2.42.
What is succinic acid?Succinic acid is one of the naturally occurring dicarboxylic acid having four carbon, which is produced by LPG.
It can be used in many chemical, food, and pharmaceutical industries.
Given,
pKa = 4.21
As we know that,
pKa = - logKa
4.21 = -logKa
Ka = antilog(-4.21)
Ka = 6.1 × 10^(-5)
Now, let the concentration of [H+] = [A-] = x
Ka = [H+] [A-] /[HA]
6.1 × 10^(-5) = x^2/ (0.25-x)
x^2 = 1.52 × 10^(-5)
x = 3.89 × 10^(-3)
Thus, the concentration of [H+] = [A-] = 3.89 × 10^(-3).
Now, we will calculate the value of pH
pH = - log[H+]
pH = -log(3.89 × 10^(-3))
pH = 2.42

How does the valency of an element show its reactiveness in a chemical reaction
Answer:
Within each group of metals, reactivity increases as you go down the group. The valence electrons are less tightly bound and easier to remove, because they are farther away from the nucleus of the atom. A nonmetal tends to attract additional valence electrons to attain a full valence shell.
