What is the heat of a reaction, in joules, with a total reaction mixture volume of 62.3 mL of the reaction causes a temperature change of 5.0 oC in a calorimeter

1,303.316 J = 1.303316 KJ.

Explanation:

The first thing to do is to calculate or Determine the mass. Thus, from the question/problem above some basic parameters or data or information were provided which is going to aid in solving this particular Question;

=> total reaction mixture volume =62.3 mL and the reaction temperature change = of 5.0 oC

The mass = density × total reaction mixture volume = 1 × 62.3 = 62.3 grams.

Therefore, the heat of a reaction = mass × specific heat capacity (C) × temperature change (∆T).

Thus, the heat of reaction = 62.3 grams × 4.184 J/g-°C × 5.0°C = 1,303.316 J = 1.303316 KJ.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

it's all four options.
