Answer:

2. 14

Explanation:

To form Br₂ bond, a total of 14 electrons are needed.

Bromine is an element in the 7th group on the periodic table. It has 7 valence electrons.

In forming the bromine gas, the two atoms of bromine shares 7 electrons each.
These electrons are from their outermost shell.
The outermost shell is the valence shell.
So, two atoms donating 7 electrons gives 14 electrons.

What particle revolves around the center of the atom? What is its Charge?

Serjik [45]

Answer:

Electrons, with a charge of -1.

Explanation:

The nucleus of the atom is composed of protons and neutrons.

The nucleus is where the bulk of the mass of an atom is found.

Electrons orbit the nucleus in various energy levels.

Protons have a charge of +1, neutrons have no charge, and electrons have a charge of -1.

Five gases combined in a gas cylinder have the following partial pressures: 3. 00 atm (N2), 1. 80 atm (O2), 0. 29 atm (Ar), 0. 1

Helen [10]

The total pressure of the gaseous mixture has been 5.37 atm. Thus, option D is correct.

The partial pressure has been defined as the pressure exerted by each gas in the mixture.

According to the Dalton's law of partial pressure, the total pressure of gas has been the sum of the partial pressure of the gases in the mixture.

The given partial pressure of gases in the mixture has been:

Partial pressure of Nitrogen, $P_N_2=3\;\rm atm$
Partial pressure of Oxygen, $P_O_2=1.80\;\rm atm$
Partial pressure of Argon, $P_A_r=0.29\;\rm atm$
Partial pressure of Helium, $P_H_e=0.18\;\rm atm$
Partial pressure of Hydrogen, $P_H=0.10\;\rm atm$

The total pressure of the gaseous mixture has been:

$P=P_N_2\;+\;P_O_2\;+\;P_A_R\;+\;P_H_e\;+\;P_H\\P=3\;+\;1.80\;+\;0.29\;+\;0.18\;+\;0.10\;\text {atm}\\P=5.37\;\rm atm$

The total pressure of the gaseous mixture has been 5.37 atm. Thus, option D is correct.
