AleksAgata [21]3 years ago
3 0

Explanation:

1) Boyle's Law: This law states that pressure is inversely related to the volume occupied by the gas at constant temperature and number of moles.

P\propto \frac{1}{V}     (At constant temperature and number of moles)

  • When the size of the chamber is increased the volume occupied the gas will increase with which pressure exerted by the gas will decrease down.
  • When we press the inflated balloon the pressure on the gas is increased with which volume of the occupied by the gas inside the balloon decreased.

2) Charles' Law: This law states that volume occupied by the gas is directly related to the temperature of the gas at constant pressure and number of moles.

V\propto T    (At constant pressure and number of moles)

  • The size of the balloon deceases because the in winters the temperature decreases with which volume of the gas present in the balloon also decreases.
  • When the flexible closed container is heated the temperature of the gas inside the container increases with which the volume occupied by the gas in the container will increase resulting in expanding of container.

3) Avogadro's Law: This law states that volume occupied by the gas is directly related to the number of moles of the gas at constant pressure and temperature.

V\propto n   (At constant temperature and pressure)

When we blow air into the balloon the umber of air particles increases with which the volume of the gas inside the balloon also increases resulting in increase in size of the balloon.

The isotope tritium has a half-life of 12. 3 y. Assume we have 11 kg of the substance. How much tritium will be left after 51 y?
Mama L [17]

Half-life is a time in which the concentration of the substance gets reduced to 50% of the initial concentration. The number of tritium that will be left after 51 years is 0.624 kg.

<h3>What is an isotope?</h3>

Isotopes are chemical substances that have the same atomic number but different atomic mass because they have a different number of neutrons in the nuclei.

The half-life of the isotope, tritium is 12.3 years. Assuming we have 11 kg of substance and a number of years 51 years.

11 \times 2 ^{\frac{-51}{12.3}} = 0.6239 \;\rm kg

Therefore, the number of tritium that will be left after 51 years is 0.624 kg.

Urea is an organic compound widely used as a fertilizer. Its solubility in water allows it to be made into aqueous fertilizer so
skad [1K]

Answer:

3 hydrogen bonds.

Explanation:

This is because the urea molecule has an oxygen atom bound with double bonds to the central carbon atom, and this oxygen can form a hydrogen bond with water, as well as both terminal amine groups that can also form a hydrogen bond each because of the lone pair of electrons on the nitrogen group.

if .40 L if water is added to the volume of cup 3, what would be the new molarity of a 2 M solution of kool-aid
stiks02 [169]

Answer:

0.7692 M ≅ 0.77 M.

Explanation:

  • It is known that the no. of millimoles of a solution before dilution is equal to the no. of millimoles of the solution after the dilution.
  • It can be expressed as:

<em>(MV) before dilution = (MV) after dilution.</em>

M before dilution = 2.0 M, V before dilution = 0.25 L.

M after dilution = ??? M, V after dilution = 0.25 L + 0.40 L = 0.65 L.

∴<em> M after dilution = (MV) before dilution/(V) after dilution</em> = (2.0 M)(0.25 L)/(0.65 L) =<em> 0.7692 M ≅ 0.77 M.</em>
