Answer:
Explanation:
A chemical reaction describes the reaction between reactants to produce products.
A chemical equation is represented as a reactant present on the left-hand side of the equation if two or more reactants are present they are separated by the "plus" sign.
On the right side of the equation product is written and if more than one product is formed then these are separated by "plus" sign as in the reactants.
The reactant and the products are separated by an arrow, the head of arrow is in the direction of the product when the reaction is irreversible.
In the case of reversible reactions or chemical reactions that are present in equilibrium, the reactant and product are separated by a double-headed arrow.

I think the correct answer from the choices listed above is the second option. The difference between speed and velocity would be that speed <span> requires distance. Velocity requires displacement. Speed only has a magnitude while velocity is a vector quantity which means it has direction and magnitude.</span>
Hello!
Whenever you see an atomic number with an element, you know the number of protons in the nucleus of the atom, which determines the chemical of an element and its place on the periodic table.
For example, Hydrogen has only one proton, however, if you were to add say 78 more protons, you'd get gold!
