Answer:
Cobalt (Co)
Explanation:
3d^7 is the location of Cobalt's last electron.
4.01 kg in grams :
4.01 x 1000 = 4010 g
Density = mass / volume
7.86 = 4010 / volume
Volume = 4010 / 7.86
Volume = 510.17 cm³
hope this helps!
Answer:
Mass is the measure of the amount of matter in an object. We see that the gravitational force between objects increases as the masses of the objects increase. With distance, we see that the strength of gravity decreases if the distance between two objects increases.
Explanation:
The amount of gravity affecting an object depends on two things: the masses of the objects being attracted and the distance between the objects. Mass is the measure of the amount of matter in an object. ... With distance, we see that the strength of gravity decreases if the distance between two objects increases
Answer:
1. S+ O2-->So2..... synthesis reaction or direct combination.
