Answer:
Gamma rays
Explanation:
The penetrating power of gamma rays is maximum as compared to beta and alpha rays. Gamma rays are nothing but the photons i.e. the packets of energy. Their energy range lies from kilo electron volts to 8 mega electron volts. It is emitted during the decay of many radioactive isotopes, such as U-238 and I-131. A large amount of energy is produced in decay of uranium 238.
Hence, the correct option is " gamma rays ".
<h3><u>Answer;</u></h3>
<u>No-</u>the equation is not balanced.
<h3><u>Explanation;</u></h3>
- The balanced equation will be;
<em>2Al + 3NiBr2→ 2AlBr3 + 3Ni</em>
- <em><u>According to the law of conservation of mass, the mass of reactants should always be the same as the mass of the products in a chemical equation. </u></em>
- Therefore, the number of atoms of each element in a chemical equation should always be the same on both sides of the equation, that is the side of reactants and side of products.
- <em><u>Balancing of chemical equations ensures that the number of atoms of each element is equal in both sides of the equation</u></em>.
The answer is A.
A positive charge’s electric field pushes out.
