Pb(OH)2 + 2 HCl = 2 H2O + PbCl2
Answer:
5.99 moles of
Explanation:
In this case, we can start with the <u>decomposition</u> of , so:
<u>(Reaction 1)</u>
The can react with carbon to produce :
<u>(Reaction 2)</u>
If we 8.99 mol of , we can calculate the moles of that we need. In reaction 2 we have a <u>molar ratio</u> of 1:2 (2 moles of will produce 1 mol of ):
With this value and using the <u>molar ratio</u> in reaction 1 (3 moles of are producing by each mol of ), so:
So, we will need 5.99 moles of to produce 8.99 mol of .
I hope it helps!
The mass number is the sum of the protons and neutrons
64 = #protons + #neutrons
Find the number of protons given the number of neutrons
64 = #protons + 33
#protons = 31
In a neutral element (such as this), the number of electrons equals the number of protons
#electrons = #protons
#electrons = 31
1.199 M is the concentration of KCI in the resulting solution.
<h3 /><h3>What are moles?</h3>
A mole is defined as 6.02214076 × of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
No.of moles of KCI
= 0.599 moles
Vol.of the solution,V= 500 ml
= 0.5 liter
Molarity
= 1.199 M
Hence, 1.199 M is the concentration of KCI in the resulting solution.
