Option A) Decreased temperature keeps gases like carbon dioxide dissolved.

Carbonation is made with CO2 which is also know as liquid carbonic. The low temperature favors higher solubility of CO2 in water

KBr (aq) + AgNO3 (aq) → KNO3 (aq) + AgBr (s)
Mnenie [13.5K]
<h3>Answer:</h3>

B Aqueous

<h3>Explanation:</h3>

We are given the equation;

KBr (aq) + AgNO₃ (aq) → KNO₃ (aq) + AgBr (s)

  • The equation shows a precipitation reaction or a double displacement reaction.
  • Precipitation reaction because two soluble salts reacts to produce a precipitate as one of the product.
  • Double displacement reaction because the salts exchange cations and anions to form new compounds
  • In the equation;
  • KBr is in aqueous state since all salts of potassium (K) are soluble in water.
  • KNO₃ and AgNO₃ are also in aqueous state as all nitrates are soluble in water.
  • AgBr on the other hand is in solid state since its a precipitate that is insoluble in water.

A 7.06% aqueous solution of sodium bicarbonate has a density of 1.19g/mL at 25°C what is the molarity and molality of the soluti
lilavasa [31]

<em>c</em> = 1.14 mol/L; <em>b</em> = 1.03 mol/kg

<em>Molar concentration </em>

Assume you have 1 L solution.

Mass of solution = 1000 mL solution × (1.19 g solution/1 mL solution)

= 1190 g solution

Mass of NaHCO3 = 1190 g solution × (7.06 g NaHCO3/100 g solution)

= 84.01 g NaHCO3

Moles NaHCO3 = 84.01 g NaHCO3 × (1 mol NaHCO3/74.01 g NaHCO3)

= 1.14 mol NaHCO3

<em>c</em> = 1.14 mol/1 L = 1.14 mol/L

<em>Molal concentration</em>

Mass of water = 1190 g – 84.01 g = 1106 g = 1.106 kg

<em>b</em> = 1.14 mol/1.106 kg = 1.03 mol/kg

What particle is needed to complete the following equation?<br> 14/7N + ____ ---&gt; 14/6C + 1/1H
yawa3891 [41]

Explanation:

The given reaction equation is as follows.

      ^{14}_{7}N + ___ \rightarrow ^{14}_{6}C + ^{1}_{1}H

As there is release of one hydrogen which shows that mass number has increase by 1 on the product side.

Therefore, particle ^{1}_{0}n must be added in order to balance the given reaction equation.

Hence, the complete reaction equation will be as follows.

      ^{14}_{7}N + ^{1}_{0}n \rightarrow ^{14}_{6}C + ^{1}_{1}H
