What is the correct energy transformation in a hydropower dam?

mars1129 [50]

Answer:

Gravitational to Mechanical to electrical

Explanation:

In a hydropower dam, the gravitational potential energy is converted to mechanical energy which in turn produces electrical energy.

The gravitational potential energy is due to the water overhead and the position of water inside the dam.
The height and quantity of water determines the magnitude of the gravitational potential energy.
Then, this energy is released when it falls on turbines and it drives them.
As the turbine moves, mechanical energy is produced.
The turbine is connected through a dynamo which produces a electric current by the turning action.

Consider the word equation. Calcium hydroxide hydrochloric acid mc012-1. Jpg calcium chloride water Which is the corresponding f

dimulka [17.4K]

The corresponding formula equation is:

Upper Ca (upper OH) subscript 2 (s) plus 2 upper H upper Cl (l) right arrow upper Ca upper Cl subscript 2 (aq) plus 2 upper H subscript 2 upper O (l)

To obtain the word equation, we shall write out the balanced molecular equation. This is given below:

Calcium hydroxide => Ca(OH)₂

Hydrochloric => HCl

Calcium chloride => CaCl₂

Water => H₂O

Calcium hydroxide + Hydrochloric —> Calcium chloride + water

Ca(OH)₂ + HCl —> CaCl₂ + H₂O

There are 2 atoms of Cl on the right side and 1 atom on the left. It can be balance by writing 2 before HCl as shown below:

Ca(OH)₂ + 2HCl —> CaCl₂ + H₂O

There are a total of 4 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 2 before H₂O as shown below:

Ca(OH)₂ + 2HCl —> CaCl₂ + 2H₂O

Now, the equation is balanced.

Thus, the corresponding word equation is:

Upper Ca (upper OH) subscript 2 (s) plus 2 upper H upper Cl (l) right arrow upper Ca upper Cl subscript 2 (aq) plus 2 upper H subscript 2 upper O (l)

What information does a subscript in a chemical formula provide? Choose all that apply. * The charge of that atom while in the c

Sloan [31]

Answer:

B. How many of each atom are present in the compound

D. the simplified ratio of atoms in relation to each other

Explanation:

In a chemical formula, chemical elements or atoms are represented by a chemical symbol for example Fe for iron and Na for sodium, and the number of each atom is represented by a subscript such as CO2, where 2 is a subscript representing 2 atoms of oxygen.

A subscript represents the number of each atom in the compound and the simplified ratio of atoms in relation to each other. The simplified ratio of atoms in relation to each other means subscript shows the contribution of both the atoms in the compound, for example: N2 + 3H2 => 2NH3, it means the subscript showing the ratio or proportionate of atoms that is 2:2 for both nitrogen and hydrogen.

The subscript is always written below and to the right of the chemical symbol.

Hence, the correct answer is "B. How many of each atom are present in the compound and D. the simplified ratio of atoms in relation to each other"

(9.0 x 108) X (3.0 x 10-4)

Fofino [41]

Answer:

25,272

Explanation:

Multiply 9.0 x 108 = 972

Multiply 3.0 x 10 = 30 - 4 = 26

Lastly, multiply 972 x 26= 25,272
