Answer: Option (4) is the correct answer.

Explanation:

Half reactions are the reactions that represent oxidation and reduction reactions through separate steps.

For example, 2Na + Br_{2} \rightarrow 2Na^{+} + 2Br^{-} the oxidation and reduction half-reaction will be as follows.

Oxidation half-reaction: 2Na \rightarrow Na^{+} + 2e^{-}

Reduction half-reaction: Br_{2} + 2e^{-} \rightarrow 2Br^{-}

Thus, we can conclude that half-reactions can be written to represent all oxidation and reduction reactions.

Show the calculation of the mass (grams) of a 14.5 liter gas sample with a molecular weight of 82 when collected at 29°C and 740
mote1985 [20]

Answer:

In this conditions, the gaswll weight 46.74 g.

Explanation:

The idal gas law states that:

PV = nRT,

P: pressure = 740 mmHg = 0.97 atm

V: volume = 14.5 L

n: number of moles

R: gas constant =0.08205 L.atm/mol.K

T: temperature = 29°C = 302.15K

n = \frac{PV}{RT} \\n = \frac{0.97x14.5}{0.082 x 302.15 } \\n = 0.57 mol

1 mol gas ___ 82 g

0.57 mol gas __ x

x = 46.74 g

ollegr [7]

Answer: The statement, you've just prepared an aqueous solution is true.

Explanation:

When one or more number of substances are dissolved in a solvent like water then solution formed is called an aqueous solution.

For example, when a hot drink is made by dissolving a teaspoon of instant coffee and a teaspoon of sugar in a cup of hot water is an aqueous solution.

Here, both coffee and sugar are solute whereas hot water is the solvent.

Thus, we can conclude that the statement, you've just prepared an aqueous solution is true.
