An energy diagram of a chemical reactions illustrates the changes of energy as the chemical reactions advances.

At first, the energy in the diagram is the energy of the reactants.

As the reaction goes forward, the reactants start to react forming a transition compound, with a maximum energy level on the graph. This is the hill. So the hill represents the Activation Energy.

After that, the energy starts to decrease and at the end you have the energy of the products, which may be higher or lower than the initial energy of the reactants, depending upon whether the reaction is exothermic or endothermic.

For exothermic reactions the energy level of the products is lower than the energy level of the reactants, while for endothermic reactions the energy level of the products is higher than the energy level of the reactants.

A bowling ball and basketball collide, what direction do they go and how is energy transferred?
olga nikolaevna [1]

Answer:

When the batter hits the ball, there is a force applied, and energy is transferred. The ball will move in the direction the force is pushing it. If two objects collide, energy will be transferred between both, and there will be a change in motion.

You are asked to weigh approximately 0. 4g of acetylsalicylic acid to the nearest mg. When you enter the data in grams in your l
Natali5045456 [20]

The significant figures will be 1.

As, weight of acetylsalicylic acid = 0. 4 g

We obtain 400 mg when we convert 0.4g of acetylsalicylic acid to mg.

So, 400 milligrams are worth 0.4 grams when converted to grams.

There is just one significant figure because 0 before a decimal is not significant i.e. 4.

<h3><u>What are significant figures?</u></h3>

The digits of a number that have relevance in relation to the measurement's resolution are known as significant figures. Additionally known as significant figures in chemistry. All experimental measurements are subject to some degree of uncertainity.
