zepelin [54]

The element which has the electronic configuration is CHLORINE.
The atomic number of chlorine is 17 and it has 7 valence electrons in its outermost shell. Because it needs only one more electrons to have a stable octet, it usually react with metals from group one of the periodic table who are normally willing to donate the single electrons in their outermost shells. The ground state electronic configuration of chlorine atom is 1S^2 2S^2 2P^6 3S^2 3P^5.

A military jet cruising at an altitude of 12.0km and speed of 1300./kmh burns fuel at the rate of 46.2/Lmin. How would you calcu

ira [324]

Answer:

2,452.12 L of fuel the jet consumes on a 1150 km mission.

Explanation:

Speed of the jet = 1300 km/h

1 hour = 60 minutes

$1300 km/h=\frac{1300 km}{60 min}=21.667 km/min$

Rate at which jet consumes fuel = 46.2 L/min

Distance covered by jet by consuming 1 liter fuel or mileage = R

R = $\frac{21.667 km/min}{46.2 L/min}=0.4690 km/L$

The amount of fuel the jet consumes on a 1150 km mission will = V

Amount of fuel = $\frac{Distance}{Mileage}$

$V=\frac{1150 km}{0.4690 km/L}=2,452.12 L$

2,452.12 L of fuel the jet consumes on a 1150 km mission.
