The correct answer is D<span>) remains hazardous for a long time. Nuclear waste stays radioactive for many centuries.
</span>
This is generally buried underground, so it does not cause significant air pollution, greenhouse effect, or acid rain<span>. These three are mostly caused by particulate matter or greenhouse gases that are emitted into the atmosphere

In the reaction,
Cr3+(aq) + 6H2O -------> [Cr(H2O)6]3+(aq)
Cr3+ IS THE LEWIS ACID H2O is the Lewis base.
A Lewis acid is a compound or chemical that accepts a lone pair of electrons. In the above equation, Cr3+ is accepting the lone pair of electrons.
Answer:
products are copper and aluminium chloride
reactants are aluminium and copper chloride
Explanation:
products are formed at the end of a reaction
reactants are what's reacting to form the products ie the things at the start of the equation
Answer:
1. In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
2. Given below are some of the examples of the chemical reactions in our daily life:
Photosynthesis.
Combustion.
Aerobic cellular respiration.
Anaerobic respiration including the process fermentation.
Metathesis reactions, for example, vinegar and baking soda.
Oxidation which includes rusting.
Digestion.
3. A chemical formula is the combination of atomic symbols that designate a particular chemical compound, or a substance with two or more different elements. ... A chemical equation shows one or more chemical compounds (reactants) being converted into different chemical species called products.
