Happy Holidays! :)

\large\boxed{\text{Water.}}

Looking at the information given in the description, the experiment is testing for the effects of the different salts on the growth of the plants.

This means that the type of salt is the independent variable,  or the variable being manipulated and tested.

To ensure fair results, some parts of the experiment would need to be kept the same, which is the control. The only answer choice that makes sense in this instance is A. water.

What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron?
vazorg [7]

Answer:

<em>What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron </em>is<u><em> energy</em></u><em>.</em>

Explanation:

The normal state of the atoms, where all the electrons are occupying the lowest possible energy level, is called ground state.

The <em>valence electrons</em> are the electrons that occupy the outermost shell, this is the electrons in the highest main energy level (principal quantum number) of the atom.

So, a <em>nonvalence electron</em> occupies an orbital with less energy than what a valence electron does; in consequence, in order to a nonvalence electron jump from its lower energy level to the higher energy level of a valence electron, the former has to absorb (gain) energy.

This new state is called excited state and is temporary: the electron promoted to the higher energy level will emit the excess energy, in the form of light (photons), to come back to the lower energy level and so the atom return to the ground state.

A student made a sketch of a potential energy diagram to represent a reaction with a -^H
OLga [1]

Answer: It’s correct because it’s showing an exothermic reaction. x is the reactants and y is the products.
