Answer:

The correct answer is "It will cause the reaction rate to increase".

Explanation:

A catalyst is defined as a molecule that increases the rate of a reaction without suffering any structural or functional alteration resulted from the reaction. The most common catalysts are called enzymes, which perform hundreds of different chemical and biological reactions. Depending on the reaction, an enzyme can increase the reaction rate up to 100 million times.

A bottle of coke is 250.0 mL. What is the volume in cubic centimeters?
hoa [83]

Answer:

The volume in cubic centimeters is 250

Explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other), the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

So:

x=\frac{c*b}{a}

The direct rule of three is the rule applied in this case where there is a change of units. To perform this conversion of units, you must first know that 1 mL = 1 cubic centimeters. So, if 1 cubic centimeters is 1 mL, how many cubic centimeters equals 250 mL?

cubic centimeters=\frac{250 mL*1 cubic centimeters }{1 mL}

cubic centimeters= 250

<u><em>The volume in cubic centimeters is 250</em></u>

A small cube of iron and a large flat sheet of iron contain the same volume. Which one will completely rust first? Explain why.
Hunter-Best [27]

The flat sheet will completely rust before the iron cube. Since they both have the same volume, the flat sheet has more surface area than the small cube. This means more particles are exposed on the flat sheet that can react in a chemical reaction.
