Answer:
120.0 kJ
Explanation:
- First we convert the given mass of C to moles:
30.00 g C ÷ 12g/mol = 2.5 mol
- The ΔH° value given by the problem, is the heat absorbed when 5 moles of C react.
So when we have<u> half the moles of C</u> (2.5 instead of 5.0), t<u>he heat absorbed will also be half</u>, thus the answer is:
Answer:
B. Matter is composed of very small particles.
Explanation:
All matter is composed of extremely small particles called atoms. All atoms of a given element are identical in size, mass,

Explanation:
We know that the process of the oxidation of SO2 to SO3 is catalysed by NO2 gas. It occurs in two stages and i will show the balanced reaction equation of the both stages below;
Step 1
2NO2(g) + 2SO2(g) ------> 2NO(g) + 2SO3(g)
Step 2
2NO(g) + O2(g) -------> 2NO2(g)
So, the overall reaction equation is;
2SO2(g) + O2(g) ------> 2SO3(g)
