The statement that is not true about the exothermic reaction is that the potential energy of the product is higher than the potential energy of the reactant. That is option D.

<h3>What is an exothermic reaction?</h3>

An exothermic reaction is the reaction that releases heat to the environment which causes increase in the immediate environment.

The characteristics of exothermic reaction include the following:

Activation energy of the forward reaction is smaller than the activation energy of the reverse reaction.

Heat is released to the environment during reaction.

Since there is release of heat, the product will have a lower energy than the reactant.

Therefore, the statement that is not true about the exothermic reaction is that the potential energy of the product is higher than the potential energy of the reactant.

A tank is filled with gasoline to a depth of exactly 2 feet. The tank is a cylinder resting horizontally on its side, with its c

inna [77]

Answer:

The volume of the gasoline in the tank is 18.85 cubic feet

Explanation:

The tank is a cylinder. The equation for calculating the cylinder volumen is πr²*h, r is radius and h is height. π is approximately 3.1416. So, The tank is resting horizontally on its side, its radius is 2 feet/2= 1 feet. h=a tank long= 6 feet.

With equation:

Vol gasoline=3.1416*1²*6=18.85 feet ³

If a 0.320 mM solution of MnO41- has an absorbance of 0.480 at 525 nm in a 1.000 cm cell. What is the concentration of a MnO41-

larisa [96]

Answer:

Hence the concentration of a MnO41- solution that has absorbance of 0.490 in the same cell at that wavelength is 0.3266.

Explanation:

Now A = el, el=const

Then,

$A2 / A1 = C2/ C1\\\\0.49/ 0.48 = C2 / 0.32\\\\C2 = 0.3266$
