Answer:
4 mol of KOH would produce 116.6 g of Mg(OH)₂
Explanation:
According to the following balanced equation:
- MgCl₂+ 2 KOH -----> Mg(OH)₂ + 2 KCL
One can note that 2 mol of KOH react with MgCl₂ to produce 1 mol of Mg(OH)₂.
using cross multiplication
2 mol of KOH → 1 mol of Mg(OH)₂.
4 mol of KOH → ?? mol of Mg(OH)₂.
no of moles of Mg(OH)₂ = (1 mol* 4 mol) / 2 mol =2 mol
Now we can convert moles of Mg(OH)₂ to grams using the formula
mass of Mg(OH)₂= (no. of moles * molar mass) = (2 mol * 58.3g/mol) = 116.6 g
- So, 4 mol of KOH would produce 116.6 g of Mg(OH)₂.
Answer is: CH4 and NaCI hope this helps you
Show a picture ! so we can know what we’re trying to find
Based on atomic properties and structure:
- Isotopes have the same proton number(atomic number) but different neutron numbers.
- An atom of barium has 56 protons and 56 neutrons in order to maintain electrical neutrality.
- The mass number of an atom is determined by the sum of protons and neutrons.
<h3>What are isotopes?</h3>
Isotopes are atoms of an element having the same atomic number but different mass numbers.
The difference in mass number is dues to different neutron numbers.
However, because they have the same proton number, they are atoms of the same element.
Neutral atoms contains equal number of protons and electrons.
An atom of barium has 56 protons and 56 neutrons in order to maintain electrical neutrality.
The mass number of an atom is determined by the sum of protons and neutrons.

Answer: Hey! As far as I know coal tar and coke are manufactured by coal.
Explanation:
Coal tar is a thick black liquid with an unpleasant smell and it is a mixture of 200 substances.
Coke is a tough, porous black substance. It is an almost pure form of carbon
(Coal mainly consists of carbon.)
