Which scenario would adhere to the law of conservation of energy?

Nina [5.8K]

Examples of scenarios that would adhere to the law of conservation of energy are as follows:

In a loudspeaker, electrical energy is converted into sound energy.
In a microphone, sound energy is converted into electrical energy.
In a generator, mechanical energy is converted into electrical energy

<h3>What is law is conservation of energy?</h3>

The law of conservation of energy states that energy cannot be created nor destroyed but is conserved when it is transferred from one form to another.

The law of conservation of energy is obeyed by majority of natural and artificial systems. For example;

In a loudspeaker, electrical energy is converted into sound energy.
In a microphone, sound energy is converted into electrical energy.
In a generator, mechanical energy is converted into electrical energy

The compounds below are to be separated by extraction. A student dissolves the compounds in either and then transfers the soluti

gulaghasi [49]

Answer:

1) Separate the aqueous layer from the organic layer using the separation funnel.

2) Treat the aqueous layer to obtain compound A.

3) Distilated the organic layer to obtain compound B.

Explanation:

When NaOH is added to the mixture the acid groups will react to produce a salt and increases the polarity of the compounds due to the net charges generated. (Figure 1).

Therefore, the salt produced by compound A will move to the aqueosus layer. Compound B dont react due to the lack of acid groups. So, this molecule will stay in the organic layer.

When the aqueous layer is separated from the organic layer using the separation funnel we will have a separation. The compound will remain in the aqueous layer and compound b will remain in the organic layer.

Then we aqueous layer can be treated with HCl in order to obtain the initial A molecule, in other words: Undo the ionic form of compound A.

The organic layer can be removed by distillation in order to obtain the pure form of compound B.

Sulfur reacts with oxygen to form sulfur dioxide (SO2(g), Hf = –296.8 kJ/mol) according to the equation below.

Pavel [41]

Given that the reactants are the very consituents (elements) of the final compound, the enthalpy change of this reaction is the same heat of formation, Hf.

That means that the enthalpy chage for the reaction is -296.8 kj/mol

Which of the following is a correct variation of the Joule's law equation? O A. P= I x R2 OB. P = V + OC. P = 12 V OD. P = V2 R

Minchanka [31]

Answer:

$P=\dfrac{V^2}{R}$

Explanation:

Power is defined as the rate at which energy is dissipated.

Its mathematical form is given by :

P = VI

Where

V is voltage and I is current

Using Ohm's law :

$I=\dfrac{V}{R}$ , R is resistance

Joule's law equation is given by :

$P=\dfrac{V^2}{R}$

Hence, the correct option is (d).
