Answer:
Option B.
Explanation:
2Pb(NO₃)₂ → 2PbO + 4NO₂ + O₂First we convert 9.90 g of Pb(NO₃)₂ into moles, using its molar mass:
9.90 g ÷ 331.2 g/mol = 0.0299 mol Pb(NO₃)₂Then we convert moles of Pb(NO₃)₂ into moles of PbO, using the stoichiometric coefficients:
0.0299 mol Pb(NO₃)₂ * [tex]\frac{2molPbO}{2molPb(NO_3)_2}[/tex] = 0.0299 mol PbONow we convert 0.0299 mol PbO into grams, using its molar mass:
0.0299 mol PbO * 223.2 g/mol = 6.67 g PbOSo 6.67 g is the theoretical yield. With that in mind we calculate the percent yield:
% yield = 5.51 / 6.67 * 100 % = 82.6%So the correct answer is option B.

Answer: 10. 39.7 g [tex]CH_3OH[/tex]
11. 650 g of [tex]HgO[/tex]
Explanation:
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]
a) moles of [tex]H_2[/tex]
[tex]\text{Number of moles}=\frac{5.0g}{2.0g/mol}=2.5moles[/tex]
[tex]CO(g)+2H_2(g)\rightarrow CH_3OH(l)[/tex]
According to stoichiometry :
2 moles of [tex]H_2[/tex] produce = 1 mole of [tex]CH_3OH[/tex]
Thus 2.5 moles of [tex]H_2[/tex] produce=[tex]\frac{1}{2}\times 2.5=1.25moles[/tex] of [tex]CH_3OH[/tex]
Mass of [tex]CH_3OH=moles\times {\text {Molar mass}}=1.25moles\times 32g/mol=39.7g[/tex]
Thus 39.7 g of [tex]CH_3OH[/tex] will be produced from 5.0 g of hydrogen.
11. [tex]2HgO(s)\rightarrow 2Hg(l)+O_2(g)[/tex]
According to stoichiometry :
1 mole of [tex]O_2[/tex] is produced by = 2 moles of [tex]HgO[/tex]
Thus 1.50 moles of [tex]O_2[/tex] are produced by =[tex]\frac{2}{1}\times 1.50=3moles[/tex] of [tex]HgO[/tex]
Mass of [tex]HgO=moles\times {\text {Molar mass}}=3moles\times 216g/mol=650g[/tex]
Thus 650 g of [tex]HgO[/tex] woukd be decomposed to produce 1.5 mol of oxygen

A tennis ball is thrown straight up with an initial speed of 20 m/s. How long does it take to reach the top of the flight?
Answer:
2.04 seconds.
Explanation:
We use an equation of motion of a body acting under gravity:
v = u + gt where u = initial velocity, g = acceleration due to gravity (9.81 m /s^-2) , v = final velocity and t = the time in seconds.
At the top of the upward journey v = 0 so we have:
0 = 20 - 9.81t (the g is negative because the gravity acts downwards).
9.81t = 20
t = 20/9.81
= 2.04 seconds.

How many milligrams of AgNO3 is required to completely react with 81.5 mg LiOH?
Balanced equation: AgNO3 + LiOH = AgOH + LiNO3
Answer:
[tex]m_{AgNO_3}=577.6mg[/tex]
Explanation:
Hello there!
In this case, according to the given chemical reaction, it is first necessary to compute the moles of reacting LiOH given its molar mass:
[tex]n_{LiOH}=81.5mg*\frac{1g}{1000mg}*\frac{1mol}{23.95g} =0.0034molLiOH[/tex]
Thus, since there is a 1:1 mole ratio between lithium hydroxide and silver nitrate (169.87 g/mol) the resulting milligrams turn out to be:
[tex]m_{ AgNO_3}=0.0034molLiOH*\frac{1molAgNO_3}{1molLiOH} *\frac{169.87gAgNO_3}{1molAgNO_3} *\frac{1000gAgNO_3}{1gAgNO_3} \\\\m_{AgNO_3}=577.6mg[/tex]
Best regards!
Answer:
AgNO3+Li-->LiNO3+Ag
It is already balanced.
And turns out to be M AgNO3=577.6mg

Which of the following is an empirical formula ?
Answer:
Explanation:
In any empirical formula problem you must first find the mass % of the elements in the compound. ...
Then change the % to grams. ...
Next, divide all the masses by their respective molar masses. ...
Pick the smallest answer of moles and divide all figures by that.
Since our answer for magnesium is not close enough to round to the nearest whole number we must choose a factor to multiply all the figures by that will yield us whole numbers

Aluminum sulfate reacts with barium chloride to form the insoluble compound, barium sulfate. The reaction proceeds according to the balanced equation below:
1Al2(SO4)3 + 3BaCl2 → 2AlCl3 + 3BaSO4
Marie reacts 150 g of aluminum sulfate with 200 g of barium chloride in order to produce insoluble barium sulfate for her crystallography studies. Determine the limiting and excess reactants for this reaction.
Molar mass aluminum sulfate: 342.15 g/mol
Molar mass barium chloride: 208.23 g/mol
Molar mass barium sulfate: 233.38 g/mol
Answer: [tex]BaCl_2[/tex] is the limiting reagent and [tex]Al_2(SO_4)_3[/tex] is the excess reagent.
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of aluminium sulphate}=\frac{150g}{342.15g/mol}=0.438moles[/tex]
[tex]\text{Moles of barium chloride}=\frac{200g}{208.23g/mol}=0.960moles[/tex]
The balanced chemical reaction is:
[tex]Al_2(SO_4)_3+3BaCl_2\rightarrow 2AlCl_3+3BaSO_4[/tex]
According to stoichiometry :
3 moles of [tex]BaCl_2[/tex] require = 1 mole of [tex]Al_2(SO_4)_3[/tex]
Thus 0.960 moles of [tex]BaCl_2[/tex] will require=[tex]\frac{1}{3}\times 0.960=0.320moles[/tex] of [tex]Al_2(SO_4)_3[/tex]
Thus [tex]BaCl_2[/tex] is the limiting reagent as it limits the formation of product and [tex]Al_2(SO_4)_3[/tex] is the excess reagent as it is left.

Which of the following molecules is the least polar?
A) H-H
B) H-CI
C) H-F
D) H-I
Answer: A) H-H is least polar
Explanation:
Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself. The more is the difference in electronegativity, the more polat the bond is.
1. H-H : Electronegativity difference = electronegativity of hydrogen - electronegativity of hydrogen =2.1 -2.1= 0
2. H-Cl : Electronegativity difference = electronegativity of chlorine - electronegativity of hydrogen = 3-2.1 = 0.9
3. H-F : Electronegativity difference = electronegativity of fluorine - electronegativity of hydrogen= 4-2.1= 1.9
4. H-I : Electronegativity difference = electronegativity of iodine - electronegativity of hydrogen= 2.5 -2.1= 0.4
Thus the least electronegativity difference between the bonded atoms is in H-H , this is least polar.
