1 answer:

6 0

Also called axis of abscissas. (in a plane Cartesian coordinate system) the axis, usually horizontal, along which the abscissa is measured and from which the ordinate is measured. (in a three-dimensional Cartesian coordinate system) the axis along which values of x are measured and at which both y and z equal zero.

Chlorine is the most widely used disinfectant for killing pathogens during water treatment. Determine the kilograms of chlorine

makkiz [27]

Explanation:

The given data is as follows.

Flow of chlorine (Q) = $10,000 m^{3}/day$

Amount of liter present per day is as follows.

$10,000 \times 10^{3} l/day$

It is given that dosage of chlorine will be as follows.

10 mg/l = $10 \times 10^{-6}$ kg/l

Therefore, total chlorine requirement is as follows.

Total chlorine requirement = $(10,000 \times 10^{3}) \times (10 \times 10^{-6})$ kg/day

= 100 kg/day

Thus, we can conclude that the kilograms of chlorine used daily at the given water treatment plant is 100 kg/day.

Fill in the numbers to interpret the isotope symbols. 92U238 has protons, neutrons, and electrons. 86Rn222 has protons, neutrons

natima [27]

Answer:

92U238 has 92 protons, 146 neutrons, and 92 electrons.

86Rn222 has 86 protons, 136 neutrons, and 86 electrons.

Explanation:

The atomic number of a chemical element is the total number of protons that each atom of that element has. It is usually represented with the letter Z.

If the atom is neutral the amount of electrons is equal to the amount of protons. Therefore the amount of electrons is equal to Z.

The atomic mass of a isotope is the total number of protons and neutrons at the nucleus of the atom. It is usually represented with the letter A.

So, the total number of neutrons is equal to n⁰=A-Z

The isotope 92U238 has A=238 and Z=92, then:

n⁰=A-Z

n⁰=238-92=146

It has 92 protons, 146 neutrons, and 92 electrons.

The isotope 86Rn222 has A=222 and Z=86, then:

n⁰=A-Z

n⁰=222-86=136

It has 86 protons, 136 neutrons, and 86 electrons.

If you can smell your grandmother’s perfume from across the room, you are experiencing the result of which liquid property?

cestrela7 [59]

The appropriate answer is D. volatility. Volatility refers to the susceptibility of liquids to vaporize. Perfume is liquid when applied but because of volatility, it has a tendency to vaporize and so it will convert to a gas and diffuse across the room. The process by which a liquid changes to a vapor is called evaporation.
