The literature value for the heat produced when Mg reacts with H+ under constant pressure conditions is - 110 kcal/mol. Calculat
Naddika [18.5K]

The accuracy obtained from the experiment can be calculated using the formula:

  • Percent accuracy = (obtained value - literature value/literature value) × 100%.

<h3>What is heat of reaction?</h3>

The heat of reaction is the amount of heat evolved or absorbed when reactant molecules react to form products.

The heat of reaction determined under standard conditions is known as standard enthalpy of reaction.

The literature value of enthalpy of reaction Mg and H+ is H+ represents the value under nearly perfectly controlled experimental conditions.

However, in imperfect experimental conditions such as in student laboratories, the value obtained may differ slightly from the literature value.

The accuracy obatined from student experiment can be calculated using the formula:

Percent accuracy = (obtained value - literature value/literature value) × 100%.

If 10g of sodium react with an unlimited amount of chlorine how much sodium chloride will get produced?
notsponge [240]

<u>Answer:</u> Amount of NaCl produced is 25.43 grams.

<u>Explanation:</u>

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\textMolar mass}}    ....(1)

  • For sodium:

Mass of sodium given = 10 g

Molar mass of sodium = 23g/mol

Putting values in above equation, we get:

\text{Moles of sodium}=\frac{10g}{23g/mol}=0.4347mol

For the reaction of formation of sodium chloride, the equation follows:

2Na+Cl_2\rightarrow 2NaCl

By Stoichiometry of the reaction,

2 moles of sodium produces 2 moles of sodium chloride

So, 0.4347 moles of sodium will produce \frac{2}{2}\times 0.4347=0.4347mol of sodium chloride.

Molar mass of sodium chloride = 58.5 g/mol

Putting values in equation 1, we get:

0.4347mol=\frac{\text{Mass of NaCl}}{58.5g/mol}=25.43g

Hence, amount of NaCl produced is 25.43 grams.
