Answer : Option A) Potential energy transforming into kinetic energy.

Explanation : When the boulder is rolling down the side of a hill, it shows that when the boulder is at rest at a certain height on the hill, it has potential energy stored in it. When it is rolling down the hill the potential energy gets converted into kinetic energy as it gains velocity while moving down the hill. So, the complete energy transformation that is occurring is potential energy to kinetic energy transfer.

Julli [10]

When energy depleted elements associated with a proton are accepted by an organic molecule the process is called Fermentation.

Fermentation is a metabolic process that causes a chemical change inside body by the actions of enzymes.

The main purpose of fermentation is to generate NAD+ and 32 ATP in the presence of oxygen.

Fermentation allows cells to survive without using ATP.

Write the TOTAL IONIC EQUATION between zinc and hydrochloric acid.
Andreyy89

Answer : The net ionic equation will be,

Zn(s)+2H^+(aq)\rightarrow Zn^{2+}(aq)+H_2(g)

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The balanced ionic equation between zinc and hydrochloric acid will be,

Zn(s)+2HCl(aq)\rightarrow ZnCl_2(aq)+H_2(g)

The ionic equation in separated aqueous solution will be,

Zn(s)+2H^+(aq)+2Cl^-(aq)\rightarrow Zn^{2+}(aq)+2Cl^-(aq)+H_2(g)

In this equation, Cl^- is the spectator ion.

By removing the spectator ion from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

Zn(s)+2H^+(aq)\rightarrow Zn^{2+}(aq)+H_2(g)

Is pOH=4.3 an acid or a base
AfilCa [17]

Answer:

a base

Explanation:

first convert the pOH to pH, that way it will

be easy to decide.

formula:pOH+pH=14

pH=14-4.3=9.7

high pH tells us it's a base

What is endothermic process?​
LiRa [457]

Answer:

An endothermic process is any process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system. It may be a chemical process, such as dissolving ammonium nitrate in water, or a physical process, such as the melting of ice cubes.
