CaC2

Ca - Group 2 metal
C - Group 4 non-metal

It is an ionic compound. :)

Explanation: Ionic compounds has a giant lattice structure with strong electrostatic forces of attraction between ions of Metal and Non-Metal. This compound require a large amount of energy/heat to overcome.

Covalent compounds has a simple molecular structure with weak intermolecular bonds with Non-metals only. This compound requires little energy/heat to overcome.

4.28 x 10^24 molecules of chlorine gas to moles of chlorine gas.​
mamaluj [8]

Answer:

7.1 moles Cl₂

Explanation:

To solve this problem we will use <em>Avogadro's number </em>(Aₙ), which tells us how many molecules (or atoms) are present in 1 mol of any given substance

Aₙ = 6.023 x 10²³ molecules/mol

With that in mind now we proceed to convert molecules into moles:

4.28 x 10²⁴ molecules Cl₂ ÷ 6.023 x 10²³ molecules/mol = 7.1 moles Cl₂

During an exothermic reaction, heat content in the surroundings increases because
ANTONII [103]

Energy is transmitted to the surrounding in an exothermic reaction and this can be understood with the energy diagram of exothermic reaction attached with the answer.

<h3>What is an Exothermic Reaction ?</h3>

When a chemical reaction happens, energy is transferred to or from the surroundings.

When energy is transferred to the surroundings, this is called an exothermic reaction, and the temperature of the surroundings increases.

ΔH value negative –> energy released –> exothermic reaction

This happens because the reactants are at the higher energy state as compared to the products and therefore heat is liberated in the atmosphere to match the difference and therefore heat content in the surroundings increases.

The energy diagram for the exothermic reaction is attached with this answer.
