A chemical reaction of exothermic kind releases energy in the form of heat and light.
We are given that reactant releases 27.4kJ/g for every gram of reactant consumed.
We are required to find number of grams of reactant that has been consumed
It is also given that 880J of energy is released
Hence, grams of reactants consumed is 880/27.4gm

Answer:
A
Explanation: A wolf is a predator and a hen is prey.
The correct answer is Three. Solving the given expression we get,
2.524 g (5.1 × 106 g) ÷ (6.85 × 103 g) = 1364.47÷ (6.85 × 103 g) = 1364.47÷ 705.55 = 1.93
Here, the number of significant figures is three. Thus, the result should have three <span>significant figures.</span>
