Ions are electrically charged particles, meaning, that whenever any type of atom loses or gains electrons it is forming a new type of structure, or ion.

Metal atoms form postive ions, Non-Metals form negative ions.

The strongest type of bond that can occur between two ions, when they are oppositely charged, are Ionic Bonds. The most commonly known ionic bond is seen in Sodium and Chlorine, which when combined give us NaCl or Sodium Chlorine, aka Salt.

+1 charge = Group 1, Metals

+2 charge = Group 2, Alkali Metals

-1 charge = Group 17, Halogens

Provided is a periodic table marked with the charges for each group.

A chemical reaction is carried out in a closed container. the energy absorbed by the chemical reaction is 100 kj. What is the en

lubasha [3.4K]

Answer:

Option A

Explanation:

The total heat absorbed during the chemical reaction is the total heat released by the surrounding.

Net change of heat is equal to zero

Hence, the energy liberated from the air or the walls of the containers would be equal to the energy absorbed by the chemical reactions is equal to 100 Kj

Thus, option A is correct

2Ni(OH) → Ni2O + H2O How many moles of water forms from 4.20 mol of nickel (I) hydroxide?

butalik [34]

Answer:

2.1 moles of water formed.

Explanation:

Given data:

Moles of water formed = ?

Moles of Ni(OH) = 4.20 mol

Solution:

Chemical equation:

2Ni(OH) → Ni₂O + H₂O

Now we will compare the moles of Ni(OH) with water.

Ni(OH) : H₂O

2 : 1

4.20 : 1/2×4.20 = 2.1 mol

2.1 moles of water formed.
