First step is to determine the valency of each of x and CaCO3 from the given compounds:
1- As for Li2CO3: we can deduce that the valency of lithium is one while that of CO3 is two
2- As for XCl3: we can deduce that the valency of chlorine is one while that of X is three
Second step is to write the required compound:
X : CO3 (elements involved)
3 : 2 (write the valency of each)
Then write the positive ion (X) followed by the valency of the negative ion (2) and then the negative ion (CO3) followed by the valency of the positive ion (3).
The final x carbonate is written as: X2(CO3)3
When water evaporates, its latent heat of evaporation absorbs heat.
<h3>What is Latent heat?</h3>
A body or thermodynamic system can release or absorb latent heat during a constant-temperature process, often a first-order phase transition.
There are two types of latent heat:
- The heat of freezing
- The heat of vaporization
The statements about water's latent heat and changes in state are:
- The heat of freezing is the quantity of thermal energy produced as a liquid freezes, and the heat of vaporization is the quantity of thermal energy needed to change a liquid into a gas.
- Water may move energy from one location to other thanks to latent heat.
- There aren't any weak (hydrogen) bonds between water molecules in the vapor state.
- Hurricanes are propelled by the latent heat of condensation, which occurs when water vapor condenses and turns into a liquid.
- All water molecules in the solid state are connected by flimsy (hydrogen) bonds.

Answer:
Rewrite the following sentence in reported speech
The chair person said,"A hearty welcome to all present!"
Answer:
The answer to your question is K = 1.48
Explanation:
Balanced chemical reaction
Br₂ + I₂ ⇒ 2IBr
Process
1.- Calculate the concentration of each of the reactants
[Br₂] = 0.6 mol / 1 L
= 0.6 M
[I₂] = 1.6 mol / 1 L
= 1.6 M
[IBr] = 1.19 M
2.- Write the equation of the Equilibrium constant
K = [IBr]² / [Br₂][I₂]
-Substitution
K = [1.19]² / [0.6][1.6]
- Simplification
K = 1.4161 / 0.96
- Result
K = 1.48
Answer:
The large the atomic radius the more the metallic character of elements
Explanation:
The atomic radius is related to the metallic character in a way that the larger the atomic radius, the more metallic a body becomes.
Therefore, as we go down a group, metallic character increases.
- Metallic character relies on the ability and willingness of an atom to share its valence electrons.
- As the size of an atom becomes large, the more metallic it is and the more its metallic character.
- In some other cases this character is known as electropositivity.
