• A particular chemical reaction releases 36.4 kJ of heat per gram of reactant consumed. To calculate the mass of reactant required to produce 1220 J of heat, you can use the following mathematical setup: First, you need to convert the heat release from kJ to J to match the units of the desired heat output: \( 36.4\ \text{kJ/g} \times 1000\ \text{J/kJ} = 36400\ \text{J/g} \) Now, you can use the heat release per gram to find out how many grams are needed to produce 1220 J: Let \( x \) be the mass of the reactant in grams. \( x \times 36400\ \text{J/g} = 1220\ \text{J} \) To solve for \( x \): \( x = \frac{1220\ \text{J}}{36400\ \text{J/g}} \) Now, calculate the value of \( x \): \( x \approx 0.0335\ \text{g} \) Therefore, approximately 0.0335 grams of reactant are required to produce 1220 J of heat.
