In quantum matter, all things in the world are made up of even smaller particles than the atom. These are called the subatomic particles: neutron, proton and electron. A beta particle is simply an electron. It is an electromagnetic particle or wave. Electromagnetic particles are high-energy particles that are emitted by the atom during radioactive decay. Since it is an electron, its charge must be -1 and it must come from outside the nucleus of the atom. From the choices, the answers would be:

is electromagnetic energy
has a -1 charge

How many grams of hydrogen are contained in 2.00 mol of C6H7N

Setler [38]

Answer:- 14.0 moles of hydrogen present in 2.00 moles of $[tex]C_6H_7N$ .

Solution:- We have been given with 2.00 moles of $C_6H_7N$ and asked to calculate the grams of hydrogen present in it. It's a two step conversion problem. In first step we convert the moles of the compound to moles of hydrogen as one mol of the compound contains 7 moles of hydrogen. In next step the moles are converted to grams on multiplying the moles by atomic mass of H. The calculations are shown as:
