Describe the three subatomic particles (protons, neutrons, and electrons) in terms of their mass, charge, and location within th

atroni [7]

Particle mass charge      location

protons    1.673*10 ^ - 27 kg 1.6*10 ^ -19 C in the nucleus
neutrons   1.675*10 ^ - 27 kg 0    in the nucleus
electron    9.11 * 10 ^ - 31 kg    -1.6 * 10 ^ - 19 C    around the nucleus (orbitals)

Protons and neutrons have almost same masses. Mass of electrons is 1/1840 the mass of the protons.

Protons and electrons have the same magnitud of charge with different sign. Protons are positive and electrons are negative. Neutrons do not have charge.

A sample of hydrogen gas collected over water occupied 30.0 mL at 24 °C on a day when the atmospheric pressure was 736 Torr. Wha

givi [52]

Answer:0.026ml

Explanation:

Details are found in the image attached. We must subtract the saturated vapour pressure of hydrogen gas at the given temperature from the total pressure of the hydrogen gas collected over water to obtain the actual pressure of hydrogen gas and substitute the value obtained into the general gas equation. The dry hydrogen gas has no saturated vapour pressure hence the value is substituted as given. All temperatures must be converted to Kelvin before substitution.

How many grams of Fe2+ are there in 0.003109 moles of Fe2+?

Sergio [31]

Answer: 0.174 g

Explanation:

First of all understand that charge on an atom like here 2+ will not vary molar mass. because ions are formed by loss or gain of electrons and electrons do not contribute to the mass of an atom or ion. so losing or gaining electron doesnt create any difference.

molar mass of Fe, i.e. mass of 1 mole of Fe is 56 g. So, mass of 1 mole of Fe2+ will also be 56 g.

given is 0.003109 moles of Fe2+,

Use maths,

1 mole of Fe2+ weighs 56 g

So, 0.003109 moles will weigh = (56 g / 1 mol ) x 0.003109 = 0.174 g.

What happens when heavy exercise results in too much acid in the human body?

White raven [17]

When heavy exercise results in too much acid in the human body, then "Lactic acid fermentation" occurs in our body. It is a metabolic process by which glucose and other six-carbon sugars <span>are converted into cellular energy and the metabolite </span>lactate, and we feel a lot of pain like burning muscles

Hope this helps!
