Answer:
1.10231×10-1 lb
Explanation:
we know that one gram is equal to the 0.00220462 lb or we can say that one pound is equal to the 453.592 g.
we have to convert the 50.0 g into pounds:
m (lb)= m(g)× 0.00220462
m(lb)=50×0.00220462
m(lb)=0.110231
in scientific notation:
1.10231×10-1 lb
Answer:
The answer to your question is: 81%
Explanation:
Data
CaO = 2 g
Ca(OH)₂ = 2.14 g
Reaction balanced
CaO + H₂O ⇒ Ca(OH)₂
Molecular mass
Calcium oxyde = 40 + 16 = 56 g
Calcium hydroxide = 40 + 2 + 32 = 74 g
Process
Rule of three
56 g of CaO -------------- 74 g of Ca(OH)₂
2 g of CaO ------------- x
x = (2 x 74) / 56
x = 2.64 g of Ca(OH)₂
Percent yield
% Yield = 
% yield = 81
Squeezing just the juices out of the orange, like with your hand or whatever you use, is a physical change. yes :)
Overall, it depends on your opinion. Some people think roses are prettier than daisies, and daisies are prettier than roses.
Roses are the definitive symbol for love and appreciation, while daisies are a symbol of Virgin Mary representing her chastity, grace, and purity. Daisies represent beauty and patience as well.
Converting to pascal
104/1000=0.104=P1
250/1000=0.25=P2
If 0.58=0.104
=0.25
Cross multiply
Solubility =[0.58*0.25]/0.104=1.39g/l
