Which quantity represents the number of protons in an atom?(a) atomic number
(b) oxidation number
(c) number of neutrons
(d) number of valence electrons

Answers

The atomic number is equal to the number of protons in an element.
The oxidation number and valence electrons can vary depending on whether it is an ion or not. The number of neutrons can also vary depending on what isotope the atom is. However, the number of protons cannot be changed without changing the identity of the base atom itself.
The answer is (a) atomic number

Atomic number = no. of protons = no. of electrons

Explanation:

Water (2190 g ) is heated until it just begins to boil. If the water absorbs 5.75×105 J of heat in the process, what was the initial temperature of the water?

Answers

Answer:

37.18°C.

Explanation:

  • The amount of heat absorbed by water = Q = m.c.ΔT.

where, Q is amount of heat absorbed by water (Q = 5.75 x 10⁵ J).

m is the mass of water (m = 2190 g).

c is the specific heat capacity of liquid water = 4.18 J/g°C.

ΔT is the temperature difference = (final T - initial T = 100.0°C - initial T).

∴ Q = m.c.ΔT = 5.75 x 10⁵ J.

5.75 x 10⁵ J = (2190 g)(4.18 J/g°C)(100.0°C - initial T)

∴ (100.0°C - initial T) = (5.75 x 10⁵ J)/(2190 g)(4.18 J/g°C) = 62.81°C.

∴ initial T = (100.0°C - 62.81°C) = 37.18°C.

Why is the chlorine that is added to final,treated waste water allowed to get used up
before it is discharged into a river or lake?

Answers

Chlorine is used as a disinfectant to wastewater treatment plants. The addition of chlorine to the final treated water is because to make sure that some of the microorganisms not killed during treatment is eliminated. It is consumed before it is released to the environment to ensure that microorganisms and other marine life are not killed in the process too.
