<u>Answer:</u> The balanced chemical equation for the reaction of nitric acid and calcium hydroxide is written below.

<u>Explanation:</u>

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

The balanced chemical equation for the reaction of nitric acid and calcium hydroxide follows:

2HNO_3(aq.)+Ca(OH)_2(aq.)\rightarrow Ca(NO_3)_2(aq.)+2H_2O(l)

By Stoichiometry of the reaction:

2 moles of nitric acid reacts with 1 mole of calcium hydroxide to produce 1 mole of calcium nitrate and 2 moles of water molecule.

Hence, the balanced chemical equation for the reaction of nitric acid and calcium hydroxide is written below.

A chemist measures the amount of bromine liquid produced during an experiment. She finds that 496g of bromine liquid is produced
vfiekz [6]

Answer:

6.208 mol

Explanation:

Mass of Bromine Liquid = 496g

Number of moles = ?

Relationship between number of moles and mass is given as;

Number of moles = Mass / Molar mass

Molar mass of Bromine = 79.9g

Number of moles = 496 / 79.9 = 6.208 mol

The higher the hydronium ion concentration of a solution, the ______ its pH.<br><br> higher or lower
andrey2020 [161]
<h3>Answer:</h3>

The higher the hydronium ion concentration of a solution, the <u>lower</u> its pH.

<h3>Explanation:</h3>
  • The pH is the measure of acidity or alkalinity of a substance.
  • We calculate pH by using;

                  pH = -log[H+]

  • The lower the pH of a solution the more acidic it is and the higher the pH the more basic or alkaline it is.
  • pH =-log[H+] =-log[H₃O+]
  • From this relationship, the higher the hydronium ions concentration of a solution the lower the pH and the more acidic a solution is.

For example,

Solution A with a [H₃O+] of 0.003 M will have a pH of

pH = -log 0.003 M

     = 2.52

While, a solution B with a [H₃O+] of 0.025 M will have a pH of

pH = -log 0.25 M

    = 1.60

Therefore, the higher the concentration of hydronium ion of a solution the lower its pH is.

A student weighs an empty flask and stopper and finds the mass to be 53.256 g. She then adds about 5 mL of an unknown liquid and
Delvig [45]

Answer:

a. The pressure in the flask open to the atmosphere during the vaporization of the unknown liquid is equal to the prevailing atmospheric pressure equivalent to 0.957734 atm

Explanation:

The mass of the empty flask and stopper, m = 53.256 g

The volume of the unknown liquid she adds = 5 mL

The temperature of the water in which she heats up the flask = 98.8 °C = 371.95 K

The mass of the flask and the condensed vapor = 53.780 g

The volume of the flask, V = 231.1 mL

The atmospheric pressure, P = 728 mm Hg

a. We note that the student stoppers the flask after all the liquid has evaporated. Therefore, given that the flask was open to the atmospheric pressure as the liquid evaporates, the pressure of the vapor in the flask is equal to the prevailing atmospheric pressure, or 728 mmHg

Using a calculator, 728 mm Hg is equivalent to 0.957734 atm.
