What is the percent yield of LiCl if I produced 30.85g LiCl and my theoretical yield was calculated to be 35.40g LiCl?
Answers
Answer:
87.15%
Explanation:
To find percent yield, we can use this simple equation
[tex]\frac{Actual}{Theoretical} *100[/tex]
Where "Actual" is the amount in grams actually collected from the reaction, and "Theoretical" is, well, the theoretical amount that should have been produced.
They give us these values, so to find the percent yield, just plug the numbers in.
[tex]\frac{30.85}{35.40} *100\\\\ =87.15[/tex]
So, the percent yield is 87.15%
An easy trick to remember how to do this is just to divide the smaller number by the bigger number and move the decimal back two places. If you have a percent yield greater than 100%, something is wrong in the reaction.

Answers
So number of moles of H2 are 0.5 in this case. And thus it means there are (6.022*10^23)*0.5 particles( here they are molecules) in 1g of H2.
Considering the definition of mass molar and Avogadro's Number, there are 3.0115×10²⁹ molecules in 1 ton of hydrogen.
First, the molar mass of hydrogen H₂, that is, the amount of mass that a substance contains in one mole, is 2 g/mole.
In this case, being 1 ton = 1,000,000 grams, the number of moles that 1 ton of hydrogen contains is calculated as:
[tex]1,000,000 gramsx\frac{1 mole}{2 grams} = 500,000 moles[/tex]
On the other hand, Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole.
Then, the number of molecules that 500,000 moles of hydrogen contains is calculated as:
[tex]500,000 molesx\frac{6.023x10^{23} molecules }{1 mole}[/tex]= 3.0115×10²⁹ molecules
Finally, there are 3.0115×10²⁹ molecules in 1 ton of hydrogen.

2 moles KCl + 3 moles O2 → 2moles KCIO3
Calculate the number of particles of each substance based on the number of moles from the balanced equation
Answers
Answer:
KCl ⇒ 1.205x10²⁴ molecules
O₂ ⇒ 1.807x10²⁴ molecules
KClO₃ ⇒ 1.205x10²⁴ molecules
Explanation:
In order to calculate the number of particles from the number of moles, we have to use Avogadro's number, which states the number of particles in one mol:
In 1 mol there are 6.023x10²³ particles (ions, molecules or atoms).So now we multiply the number of moles of each substance by Avogadro's number:
KCl ⇒ 2 mol * 6.023x10²³ molecules/mol = 1.205x10²⁴ moleculesO₂ ⇒ 3 mol * 6.023x10²³ molecules/mol = 1.807x10²⁴ moleculesKClO₃ ⇒ 2 mol * 6.023x10²³ molecules/mol = 1.205x10²⁴ moleculesWhen aqueous ammonia is added to a solution containing Bi3+ and Cu2+ cations, ____________ occurs.

Answers
Answer:
C. Precipitation of white bismuth hydroxide.
Explanation:
When aqueous ammonia is added to a solution that has Bi3+ and CU2+ cations, what we would have as a chemical result is the precipitation of white Bismuth hydroxide.
The chemical reaction for this can be written as,
Bi3+ + 2NH3 + 3H2O ⇌ Bi(OH)3(s) + 3NH4

What is the pressure (in atm) in a 5.00 L tank with 9.00 grams of oxygen gas at 350 K?
Answers
Answer:
1.61 atm
Explanation:
Using general gas law equation as follows:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
From the information provided in this question,
V = 5.00L
T = 350K
mass of O2 = 9.00g
Using mole = mass/molar mass
Molar mass of O2 = 16(2) = 32g/mol
mole = 9/32
mole = 0.28mol
Using PV = nRT
P = nRT/V
P = 0.28 × 0.0821 × 350/5
P = 8.0458/5
P = 1.609
Pressure = 1.61 atm
The pressure of the oxygen gas at the given temperature and volume is 1.61 atm.
The given parameters;
volume of the gas, V = 5 Lmass of the oxygen gas, m = 9 gtemperature of the gas, T = 350 KThe number of the moles of the given gas is calculated as follows;
[tex]moles = \frac{m}{M} \\\\moles = \frac{9}{32} \\\\moles = 0.28 \ mol[/tex]
The pressure of the gas is calculated as follows;
[tex]PV = nRT\\\\P = \frac{nRT}{V} \\\\P = \frac{0.28 \times 0.0821 \times 350}{5} \\\\P = 1.61 \ atm[/tex]
Thus, the pressure of the oxygen gas at the given temperature and volume is 1.61 atm.

why does a mole of silicon weigh a different amount than a mole of carbon?
Answers
Answer:
[tex]\boxed {\boxed {\sf Different \ amount \ of \ protons, neutrons, \ and \ electrons}}[/tex]
Explanation:
Remember that a mole is equal to Avogadro's number: 6.022*10²³ atoms. Also, remember that an atom is made up of protons, neutrons, and electrons. Each element has a different amount of each.
If an element has more of these particles in 1 atom, then the atomic mass will be greater, ultimately making the molar mass (mass of 1 mole) greater.
Silicon has 14 protons, electrons, and neutrons, making its atomic mass 28.085 amu and its molar mass 28.085 grams. However, carbon only has 6 of each particle, so its atomic mass is smaller at 12.011 amu and molar mass is 12.011 grams.
