Why is fossil fuel considered a nonrenewable energy source?​

Chemistry
1 answer:
IRINA_888 [86]3 years ago
3 0

Answer:

\boxed {\tt Takes \ many \ years \ to \ replenish}

Explanation:

A nonrenewable is a resource that cannot quickly be regenerated. A nonrenewable resource will eventually run out, and it cannot be remade for many years.

For example, <u>fossil fuel </u>is formed from fossils after millions of years of heat and pressure turn them into fuel. Since they take many years to create, they are a <em>nonrenewable energy source.</em>

In a voltaic (galvanic) cell, oxidation occurs at the _____ and is where _____ in the salt bridge moves toward.
Anna11 [10]

In a voltaic (galvanic) cell, oxidation occurs at the <u>anode</u> and is where <u>anions</u> in the salt bridge moves toward.

<h3>What is Galvanic Cell ?</h3>

Galvanic Cell or Voltaic Cell is an electrochemical cell that converts the energy of spontaneous redox reactions into electrical energy. In galvanic cell oxidation occurs at the anode and reduction occurs at the cathode. The anode is positive and cathode is negative, anode attracts anions from solution in an electrolytic cell.

Thus from the above conclusion we can say that In a voltaic (galvanic) cell, oxidation occurs at the <u>anode</u> and is where <u>anions</u> in the salt bridge moves toward.

What does Gibbs free energy predict?
7nadin3 [17]

Answer:

D. It predicts whether or not a reaction will be spontaneous.

Explanation:

<em>What does Gibbs free energy (ΔG) predict? .</em>

A. It predicts what the rate of the reaction will be. NO. ΔG is a thermodynamical parameter and it is not related to the kinetics of the reaction.

B. It predicts how high the activation energy is. NO. ΔG is a thermodynamical parameter and it is not related to the kinetics of the reaction.

C. It predicts if entropy will increase or decrease. NO. ΔG depends on the entropy but not the other way around.

D. It predicts whether or not a reaction will be spontaneous. YES. If ΔG < 0 the reaction is spontaneous and if ΔG > 0 the reaction is not spontaneous.

How is the energy divided up in the plant
Lerok [7]
When a crop of wheat grows, new organic matter is created by the process of photosynthesis, which converts light energy into energy stored in chemical bonds within plant tissue. ... New compounds and structures are synthesized, cells divide, and the plant grows in size over time

Consider the following data for five hypothetical elements: Q, W, X, Y, and Z. Rank the elements from most reactive to least rea
Natalka [10]

Answer:

Y, Q, W, Z and X

Y > Q > W > Z > X

Explanation:

To know the most reactive element, the element will be able to displace other metal in it compound. We also have to observe if the reaction occur. If the reaction didn't occur, that means the element is not reactive than the metal found in the other reactant. Invariably their will be no displacement.

Q + w+ Reaction occurs

Q element displace the metal w in it compound . This means Q is more reactive.

x +z+ No reaction

No reaction here. This means x is less reactive than z as it couldn't displace z in it compound.

w + z+ Reaction occurs

w is more reactive than z as it displaces z in it compound.

Q+ + Y Reaction occurs

Y is more reactive than Q as it displaces Q in it compounds.

Therefore, the most reactive to the least reactive is arrange as follows.

Y, Q, W, Z and X

What does a salt bridge do?
Andrew [12]

Answer:

A salt bridge or ion bridge, in electrochemistry, is a laboratory device used to connect the oxidation and reduction half-cells of a galvanic cell (voltaic cell), a type of electrochemical cell. It maintains electrical neutrality within the internal circuit.
