Answer:
When fossil fuels are burned carbon and hydrogen react with oxygen in air to carbon dioxide (CO2) and water (H2O). During this reaction heat is released which further amplifies the reaction. Electricity is generated by transforming mechanical energy (heat) to electrical energy in a turbine or generator.

Explanation:
Conductivity of a solution refers to its ability to conduct electricity. It is a measure of how much the solution can conduct electricity.
Looking at the reaction; Ba(OH)2(aq) + H2SO4(aq) ---------->BaSO4(s) + 2H2O(l)
We can see that the concentration of ions in solution decreases from left to right. As the concentration of ions decreases, the conductivity of the solution decreases accordingly since conductivity of solution depends on the concentration of ions in solution.
Also, the solution appears cloudy as the reaction progresses due to the formation of BaSO4(s).
For most non-electrolytes, the Van’t Hoff Factor is essentially 1.
Answer:
3.4 × 10
^−
4
Explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
