Decreasing the temperature in the reaction vessel keep this reaction from shifting to form more of the product.
As we know that rate of reaction is directly proportional to the concentration of the reactant.
If we increase the concentration of H2 then the rate of reaction increases. So, we keep it constant. Therefore this option is wrong.
By removing the H₂O from the reaction vessel as it almost make no change in the reaction. This can be pursuited the reaction in which product again converted into product.
By increasing the temperature we increases the rate of reaction and equilibrium shift in the forward direction.
Thus, we concluded that by decreasing the temperature in the reaction vessel keep this reaction from shifting to form more of the product.

Answer:
<u><em /></u>
- <u><em>Br²⁺ (g) → Br³⁺ (g) + e⁻</em></u>
Explanation:
1) The <u>first ionization energy</u> is the energy required to release an electron from a gas neutral atom.
Hence, this is the energy required for this process:
2) The <u>second ionization energy </u>is the energy required to release an electron from a gas ion with charge 1+.
Hence, this is the energy required for this process:
3) The<em><u> third ionization energy</u></em> is the energy required to release an electron from a gas ion with charge +2.
Hence, this is the energy required for this process:
<u />
- <u><em>Br²⁺ (g) → B³⁺ (g) + e⁻</em></u>
Due to the high strength of iron compared to that of barium and phosphorus the nails are made of iron.
Though iron oxidizes to form rust on reacting with water but it does not explode. Whereas barium reacts vigorously with water with evolution of hydrogen gas. Barium on reacting with other nonmetals results in the formation of poisonous substances. Phosphorus is never found in its pure form in nature and is combustible.
Hence, nails are made up of iron but barium and phosphorus are not suitable for making of nails.
Answer: aluminium, mercury , platinum and copper.
Explanation:
A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.
A general single displacement reaction can be represented as :
Thus the metals which are more reactive than magnesium will react with magnesium sulphate solution.
The metals which are more reactive than magnesium are aluminium, mercury , platinum and copper.
Answer:
A planet's orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.
