Firdavs [7]3 years ago
6 0

Answer:

Because the student made use of scientific instruments in one case and his senses in the other.

Explanation:

Scientific experiments involve making observations, which is key to the outcome of any experiment. According to the scientific method, collecting of data is one of the steps in fulfilling the scientific procedure. One way to collect data is by using scientific instruments to measure, which is then recorded. This is the case for the WEIGHT of the sugar the student recorded.

Another way to collect data is by making use of the senses e.g eyes, nose, skin etc. to observe and record the perceived information. Therefore, the pieces of information collected by the student represent DATA because he made use of his senses and scientific instruments.

2SO3(g)⟶2S(s)+3O2(g)ΔH=+790kJ. How many kilojoules are required when 2.1 moles of SO3 reacts?
guapka [62]

<u>Given:</u>

Enthalpy change (ΔH) for SO3 decomposition = +790 kJ

Moles of SO3 = 2.1 moles

<u>To determine:</u>

Energy required when 2.1 moles of SO3 reacts

<u>Explanation:</u>

The decomposition reaction is -

2SO3(g) → 2S(s) + 3O2 (g)

Energy required when 2 moles of SO3 reacts is 790 kJ

Thus, for 2.1 moles of SO3 the energy requirement would be

= 2.1 moles SO3 * 790 kJ/2 moles SO3 = 829.5 kJ

Ans: 830 kJ are required when 2.1 moles of SO3 reacts.
