Answer:

The energy of the products is less than the energy of the reactants, so energy is released into the surrounding environment.

Answer:

The correct answer is The energy of the products is less than the energy of the reactants, so energy is released into the surrounding environment.

Explanation:

In exothermic reactions, there is a release of energy in the environment which comes out converted into heat. These types of reactions are the <u>product of a process of transformation of molecules called chemical reaction.</u>

The energy that an exothermic reaction uses to carry out is less than the amount of energy it releases, so as the answer says: This energy is released because the energy of the products is less than the energy of the reactants.

An exothermic change can be for example the processes of condensation and solidification.

Which of the following accurately describes the behavior of water when subjected to temperature change?
77julia77 [94]
I believe this is the best one:
B. The volume of water will increase if cooled from 3°C to 2°C.

I don't think D) because water expands from 4°C to 0°C

"When liquid water is cooled, it contracts like one would expect until a temp of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point."

If 5.58 g of iron reacts with sulfur to produce 8.79 g of iron sulfide, what is the mass of reacting sulfur? A) 3215 B) 14:37 C)
gogolik [260]

Answer: A) 3.21 g

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side.

Fe+S\rightarrow FeS

We are given:

Mass of iron = 5.58 g

Mass of iron sulphide = 8.79 g

Mass of sulphur = x g

Total mass on reactant side = 5.58 + x

Total mass on product side = 8.79 g

Applying law of conservation of mass, we get:

5.58+x=8.79\\\\x=3.21g

Hence, the mass of reacting sulfur is 3.21 g.
