Explanation:
The concept applied here is the application of change of state as such ,
A reversible reaction is one that can go in both ways, that is the forward reaction can react to produce the product and the backward reaction can also react to give back the reactants. In a reversible reaction, no new substances are formed and the heat evolved is not much compared to Irreversible reaction.
An Irreversible reaction is one that can not go in both ways. i.e reactants can react to give products but products cant react to give back the reactants. In irreversible reaction, new substances are formed and a huge amount of heat is evolved.
There is reversibility between melting point and freezing point, the differences is if the solid is melting above its melting point, in such case, it is an irreversible reaction.
Answer:
indeed it 1s22s22p63523p645230104p5 is bromine
Hydrogen gas
Explanation:
Expression:
CO₂ + H₂ → CO + H₂O
Hydrogen gas in this reaction is oxidized in the reaction.
In this manner, it is the reducing agent in the reaction.
A reducing agent is the specie in a chemical reaction that undergoes the process of oxidation.
It is marked by:
- Addition of oxygen to a specie
- Removal of hydrogen from a specie
- Loss of electron by an atom
- Increase in oxidation number
- Increase in number of electronegative atoms surrounding a specie.
Here we see that H₂ fits this criteria perfectly well.
CO₂ is the one reduced.

Answer:
I guess its because of friction
Explanation:
friction kills the cells of surface

<span>1. In any nuclear reaction, nuclei are transformed in some way.
True
2. Two fissionable substances commonly used in nuclear reactors and nuclear weapons include uranium-235 and plutonium-239.
True
3. Fission reactions can be controlled; thus, they are used to create energy and electricity. But fusion reactions are uncontrollable and require too much energy for economical use.
True
4. Fission reactions occur at such high temperatures in the Sun that the Sun appears to glow.
False
