A chemist wants to observe the following reaction:
stiv31 [10]

It take more energy to break the bonds of the reactants and less energy is given off when the product bonds are formed.

<h3>What is Energy?</h3>

Energy is defined as the ability to do work. Work is done in the breaking or formation of bonds.

The standard Enthalpy (ΔH) of water which was formed in the given reaction is negative.

ΔH= Δproduct - Δreactant

This means that the energy to break the bonds of the reactants is more.

When heat is applied gradually and evenly to solid ice at 0 Celsius, it melts. Does the temperature change while it is melting t
serious [3.7K]

No, the added heat melts the ice, but the result is water at the same temperature. Hence, option B is correct.

<h3>What is temperature?</h3>

The degree of hotness or coldness is measured on a definite scale.

Temperature doesn't change as heat is added during a phase change; for example, when the ice melts.

During the phase change, the added heat doesn't make the molecules move faster, but rather further apart.

Thus, No, the added heat melts the ice, but the result is water at the same temperature.

In which environment would a forensic scientist not be found?
mrs_skeptik [129]

The correct answer is D. In a police interrogation room, questioning the suspect.

Explanation:

Forensic scientists are experts who use science as part of criminal investigations. Indeed, the main role of these experts is to deal with the evidence related to the crime to help authorities understand how the crime occurred and who was involved in this.

Because of this, the forensic scientist's role includes collecting evidence, analyzing samples, participating as witnesses in trials, and in some cases teach other experts about techniques. However, forensic scientists cannot interrogate suspects as they only deal with evidence and this process is in charge of the police.
