Answer:

Energy is converted in a hydroelectric plant as follows;

The kinetic energy of water turns turbines; the mechanical energy of the turbines turns the generator, which produces electrical energy

Explanation:

The water in an hydroelectric plant is given potential energy by building an artificial dam to raise the height of the water above the turbine

The high potential energy of the water is converted to kinetic energy which provides the power that turns the turbine transforming the kinetic energy of the water into rotational kinetic energy of the turbine by conservation of mechanical energy;

The shaft connected between the turbine and the generator, turns the generator by the mechanical energy of the turbine and as the generator turns in a magnetic field, electricity is produced by magnetic induction according to Faraday's law.

Prob.: Consider the combustion of butane (C4H10):

never [62]

Answer: The moles of carbon dioxide formed in the reaction is 20 moles.

Explanation:

We are given:

Number of moles of butane = 5.0 moles

The chemical reaction for the combustion of butane follows the equation:

$2C_4H_{10}(g)+13O_2(g)\rightarrow 8CO_2(g)+10H_2O(l)$

As, oxygen is present in excess. So, it is considered as an excess reagent.

Thus, butane is considered as a limiting reagent because it limits the formation of products.

By stoichiometry of the reaction:

2 moles of butane produces 8 moles of carbon dioxide.

So, 5 moles of butane will produce = $\frac{8}{2}\times 5=20mol$ of carbon dioxide.

Hence, the moles of carbon dioxide formed in the reaction is 20 moles.
