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

Explanation:
Electron affinity is the energy change that results from adding an electron to a gaseous atom(Khan Academy). It is also defined as "the amount of energy released when an electron is attached to a neutral atom or molecule in the gaseous state to form a negative ion" (Wikipedia).
Electron affinity increases from left to right in the periodic table. However, the noble gases possess a complete outermost electron shell.
Hence, electron affinity can be raked from the most negative to the least negative for the three atoms as follows; Br>Ge>Kr

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.

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.

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.
The________ cation will precipitate after the_________ step. Then the _________cation will precipitate after the________ step.

b. first
c. second
d. third
e. Al^3+
f. Sn^4+
Answer:
f. Sn^4+
c. second
e. Al^3+
d. third
Explanation:
This question comes from a quantitative analysis showing the flowchart of a common scheme for identifying cations.
Now, from the separation scheme, Let's assume that Sn⁴⁺ & Al³⁺ were given; Then, Yes, the separation will work.
However, there will be occurrence of precipitation after the 1st step1.
So, the Sn⁴⁺ cation will precipitate after the second step. Then the Al³⁺ cation will precipitate after the third step.

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
