The Balance Chemical Equation is as follow,
2 HCl + Pb(NO₃)₂ → 2 HNO₃ + PbCl₂
According to equation,
331.2 g (1 mole) Pb(NO₃)₂ produces = 278.1 g (1 mole) PbCl₂
So,
870 g of Pb(NO₃)₂ will produce = X g of PbCl₂
Solving for X,
X = (870 g × 278.1 g) ÷ 331.2 g
X = 730.5 g of PbCl₂
Therefore,
Theoretical Yield = 730.5 g
Also as given,
Actual Yield = 650 g
So using following formula for percentage yield,
%age Yield = (Actual Yield / Theoretical Yield) × 100
Putting values,
%age Yield = (650 g / 730.5 g) × 100
%age Yield = 88.98 %
Brianliest please and thank you.
1) All matter is made of atoms. 2) Atoms are indivisible and indestructible.
Hello my friend,
since atomic no. = no. of electrons
there will be 40 electrons in that atom.
if and element has 111 protons, atomic no. will be 111.
no. of neutron = 161 - 55 = 106 neutrons.
Answer:
4.1/
Explanation
Do the calculation carefully because this calculation has negative term.
I hope you will understand.
3/8 + 7/2 + (-3/5) + 9/8 + (-3/2) + 6/5
31/5+(-3/5)+(-3/2)
