Answer:

See explanation

Explanation:

When we are writing chemical reaction equations, we must ensure that such equations are balanced. That is, the number of atoms of each element on both sides of the reaction equation are exactly the same.

After we identify the formula of each compound in the reaction, then we proceed the write the balanced reaction equation as follows;

CuCl2 + 2AgNO3 -------> Cu(NO3)2  + 2AgCl


How do the mass number and atomic change as a particle goes through beta decay

Answers

Answer:

The atomic mass number does not change because a beta particle has a much smaller mass than an atom. The atomic number goes up because a neutron has turned into an extra proton, however in beta decay a fast-moving electron is fired out of the nucleolus

Answer:

The cool people like me XD

Explanation:

Answer:

Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy. In the solid the particles vibrate in place. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart.
