What does the energy hill represent on an energy diagram?
Butoxors [25]

Answer:

The correct answer is option D.

Explanation:

When a chemical reaction proceeds the reactants are converted into products. The energy hill represents the potential energy of the reaction.

There are two conditions: If the reaction is endothermic than the energy of the products is greater than the energy of the reactants and  ΔH  is positive. This energy gain is shown in the form of a peak.  In an exothermic reaction, the energy of the products is lower than the reactants and  ΔH  is negative.

So the suitable option is D which states that the reaction is endothermic and the potential energy gained by the products is higher when a reaction proceeds.

A chlorine atom has a diameter of 175 picometers (pm). Please write the diameter, in metered, in scientific notation.
IrinaVladis [17]
The answer is 1.75 x 10¹⁰ m.
Scientific notation<span> refers to a mathematical expression that is  used to represent a decimal number between 1 and 10 multiplied by ten, or we can say that to write a large numbers using less digits. 
Diameter of chlorine atom = </span><span>175 picometers (pm) 
</span>175 pm = <span>0.000000000175 m
in scientific notation we will write </span>0.000000000175 m as <span>1.75 x 10</span>¹⁰ m
