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.
Answer:
It increases the amount of carbon dioxide in the air, enhancing global warming.
Explanation:
When deforestation occurs, carbon dioxide ultimately gets released in the
surrounding environment, causing global warming to increase in proximity
and way. Thus, the answer is greatly supported with legitimate facts.
I hope this helped!!

Diamond is an allotrope of carbon; that just means it is a different crystalline structure, but pure diamond contains only carbon atoms. (unrelated, but interesting - colored diamonds come from impurities like boron and nitrogen in the crystal structure!) The molar mass of carbon is 12.01 g/mol. You can find the molar mass by looking at the periodic table. If you look under number 6, Carbon, you should see the atomic weight right under it: 12.01. The molar mass is this same number, in grams. That means that one mole, or 6.022E23 carbon atoms, weigh 12.01 grams.
<span>But you don't have one mole. You only have 2 grams. </span>
<span>So how many moles do you have? 2 grams out of 12 grams. 2/12 = 1/6 or 0.167. You have 1/6th of a mole. One mole is 6.022E23 atoms, but you only have 1/6th of that. I hope that thinking about it stepwise like this makes sense to you. It works the same for other atoms and molecules too. In a molecule, you would just add up the molar mass of all the component atoms. I hope this helps.
