D. chemical bonds between reactants.

In a chemical reaction, the reactants break and establish new bonds between atoms by exchanging electrons. The overall atomic mass doesn't change. Element identities only change with a loss or gain of protons, which happen in nuclear reactions. The total number of electrons does not change, just become exchanged or shared between atoms.

A bird is flying in the air at a 4 m/s. If the mass of the bird is 7kg what is it’s kinetic energy

yaroslaw [1]

Answer: The kinetic energy of the flying bird is 56 Joules.

Explanation:

Mass of the bird = 7 kg

Velocity of the flying bird = 4 m/s

Kinetic energy of the bird will be given by :

$K.E.=\frac{1}{2}mv^2$

$K.E.=\frac{1}{2}\times 7 kg\times (4 m/s)^2=56 Joules$

The kinetic energy of the flying bird is 56 Joules.

Explain how humidity ,pressure, and temperature result in cloud cover.

Anarel [89]

Explanation:

Temperature is the amount of heat energy contained in the air, and we measure this in degrees. Air pressure is the amount of pressure exerted by the air in a particular air mass. Humidity is a measure of the water content of the air mass. Clouds are tiny drops of water or ice that form in the atmosphere.
