. If this same atom with 22 protons and 19 electrons were to gain 3 electrons, the net charge on the atom would be
frez [133]

Answer: No charge (0)

Explanation:

The atom has a proton of 22 and electron number of 19. This means the element has lost 3 electrons. Therefore, the net charge is +3.

So, if this atom gains 3 more electrons, the net charge would be zero (neutral).

The total number of electron would now be 22 which is the same as the proton number.

This implies the atom is now in an unreacted state or ground state.

During World War One, observation balloons were used in order to spy out enemy positions. An observation
blondinia [14]

Answer:

0.971

Explanation:

The pressure (P) in atmospheres (atm) the balloon was filled to will be

P = P1 +P2 + P3

where P1 is the pressure in atm of Helium (0.5 atm)

P2 is the pressure in atm of Nitrogen (X atm)

P3 is the pressure in atm of Hydrogen (0.4 atm)

The value of P2 provided in the question is in mmHg

To convert we have

1 atm = 760 mmHg

X atm = 54 mmHg

X = 54 × 1/760

X =  0.071 atm

Hence, P2 = 0.071 atm

Thus, from the formula earlier

P = 0.5 + 0.071 + 0.4

P = 0.971 atm
