An isotope of nitrogen containing 7 neutrons would be nitrogen-7
Answer: As the airplane goes higher, the mechanical energy is changed into gravitational potential energy. While flying, some energy is lost through drag to thermal (heat) energy and sound energy. Some is also lost as the plane makes the air around it move. ... As speed and height decrease, kinetic and potential energy decrease.

Answer:
different from the number of their neutrons
Explanation:
They each have one single proton (Z = 1), but differ in the number of their neutrons. Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. ... Their nuclear symbols are therefore 1H, 2H, and 3H. The atoms of these isotopes have one electron to balance the charge of the one proton.
Answer:
0.0250 g
Explanation:
176.12 g/mol* 0.000142 mol =0.0250 g
Calcium chloride because it makes three ions for every one compounds. Colligative properties are affected by moles of substance that disrupt the surface tension. Sodium chloride makes only two and molecular substances don't dissociate
