In balancing reactions, the number of atoms on each side should be of equal number. It is the most important rule in reactions. Also, we should know the correct substances involved in the reaction. We do as follows:

2K + MgBr2 = 2KBr + Mg

Answer:

The reaction is:

2K(s) + MgBr₂(s) --> 2KBr(s) + Mg(s)

Explanation:

The reaction between potassium and magnesium bromide can be balanced by considering the fact that one mole of magnesium bromide will react with two moles of potassium to give two moles of potassium bromide and one mole of Magnesium.

Thus the balanced equation will be:

2K(s) + MgBr₂(s) --> 2KBr(s) + Mg(s)

How many moles of water are produced when 5 moles of hydrogen gas react with 2 moles of oxygen gas?
Marysya12 [62]

4 moles of water are produced

Explanation:

  • 4 moles of water are produced when 5 moles of hydrogen is reacted with 2 moles of oxygen gas
  • The balanced equation given is when 2 moles of hydrogen reacts with 1 mole of oxygen and it forms 2 moles of water.
  • The equation we have to solve is the 5 moles of hydrogen is reacting with 2 moles of oxygen gas, we can write the equation as 5H_{2} +2O_{2} -->  4H_{2} O + H_{2}
  • This is the balanced equation when 5 moles of hydrogen reacts with 2 moles of oxygen. The balanced equation means the number of hydrogen atoms and oxygen atoms on both sides would be equal in number.

Convert 1.7 Kg to cg
Kipish [7]
To answer this lets first see how much 1 kg is equal to in cg.

1 kg = 100000 cg 

Now lets multiply:-

100000 × 1.7 =  <span>170000
</span>
So, 1.7 kg = <span>170000 cg
