How many liters of oxygen at stp are needed to react with 5.2 * 10 to the 22nd power molecules of hydrogen sulfide?

Answers

Answer 1

Answer: For the reaction H2S + 2 O2 -> H2SO4

starting with 5.2 x 10^22 molecules of H2S we can calculate the number of moles H2S by dividing by 6.02 x 10^23

We have 0.086 moles H2S

1 mole of H2S reacts with 2 moles of O2 so we need 0.17 moles of O2

1 mole of all gases at stp occupy 22.4 liters of space

.17 x 22.4 = 3.08 liters of O2 needed to react with 5.2 x 10^22 molecules of H2S

Compounds put together will form -a. elements.
b. mixtures.
c. atoms.
d. pure substances.

Answers

The correct answer is B. Compounds put together will form mixtures because compounds itself are pure substances which contains elements and atoms. Mixtures is a system that is made up of two or more substances or compounds which are not combined chemically.

32 What is the overall charge of an ion that has 12 protons, 10 electrons, and 14 neutrons?(1) 2- (3) 4
(2) 2+ (4) 4+

Answers

The charge of a proton is +1, of an electron is -1, and of a neutron is 0.

12*(+1) +10*(-1) +14*0
= 12 -10
= +2

The correct answer is (2) +2.

Hope this would help~

protons have a 1+ charge
Electrons have a 1- charge
So 12-10 is 2+

Based on intermolecular forces, which of these substances would have the highest boiling point?(1) He (3) CH4
(2) O2 (4) NH3

Answers

NH3 would have the highest boiling point because the molecules have all 3 types of bonds:
London dispersion, because all molecules do
Hydrogen Bond, because of the fact that hydrogen is present and so is Nitrogen, one of the elements that hydrogen will form a hydrogen bond with.
Dipole Bond: Because the NH3 has a lone pair

Answer: NH3

Hope this helped!!!

Based on intermolecular forces, NH3 would have the highest boiling point.

An experiment requires 40.0g of ethylene glycol, a liquid whose density is 1.114 g/mL. Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder. What volume of the liquid should he use?

Answers

Density= mass/volume
volume=mass/density
volume= 40.0g/1.114g per mL
volume= 35.90664273 mL
volume = 35.9 mL
