VashaNatasha [74]

The answer is <span>the reaction will shift to the left (toward the reactants).

Reaction is at equilibrium can be expressed as,
      Reactants </span>⇄ products<span>

<span>After coming to the equilibrium, if one condition is changed, then according to the </span>Le chatelier's Principal,<span> the system will act to maintain the equilibrium by reducing the effect. As an example, if we reduce the pressure, then system acts to increase the pressure to maintain the equilibrium.</span>

<span>Likewise, if we add products into the reaction which is in equilibrium, the system acts to reduce the effect by promoting the backward reaction to produce reactants.</span></span>

fomenos

Answer:

<h2>30.2 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

volume = final volume of water - initial volume of water

From the question

volume = 35.9 ml - 25.8 ml = 10.1 mL

We have

mass = 2.99 × 10.1 = 30.199 g

We have the final answer as

<h3>30.2 g</h3>

Hope this helps you
