Answer:

The one left in the hot sunlight.

Explanation:

The solubility of gases decreases when temperature increases. The gas in the soda pop (CO2) left in the sun will not stay dissolved as much as the on left in the refrigerator.

Rank the solutions below in order of increasing acidity. (Drag and drop into the appropriate area)
Vladimir79 [104]

Answer:

0.1 M NaOH, 3 M NH3, 0.01 M CH3COOH, 0.01 M H2SO4, 0.1 M HCl

Explanation:

Strong acids are more acids than weak acids. In the same way, strong bases are more basic than weak bases that are in the same concentration.

Then, the more concentrated acid or base will be more acidic or basic.

CH3COOH. Weak acid

NaOH. Strong base

H2SO4. Strong acid

NH3. Weak base.

HCl. Strong acid

The less acid (More basic):

<h3>0.1 M NaOH, 3 M NH3, 0.01 M CH3COOH, 0.01 M H2SO4, 0.1 M HCl</h3>

Strong base, weak base, weak acid, diluted strong acid, undiluted strong acid

An element has 2 neutrons, 2 electrons and 2 protons. Which element does this describe? Is it a neutral atom, isotope, or an ion
Y_Kistochka [10]

Considering the definition of neutral atom, mass number and net charge, the element is a neutral atom, with a net charge equal to zero and a mass number of 4.

<h3>Neutral atom and ion</h3>

All atoms are made up of subatomic particles: protons and neutrons, which are part of their nucleus, and electrons, which revolve around them. Protons are positively charged, neutrons are neutrally charged, and electrons are negatively charged.

A neutral atom is one that has no electrical charge because it has the same number of protons and electrons.

In contrast, ions are atoms or groups of atoms that have an electrical charge and are formed by the gain or loss of electrons from the atom.

<h3>Mass number</h3>

The mass number tells us the total number of particles in the nucleus. That is, the mass number is the sum of the number of protons and the number of neutrons in the atomic nucleus:

Mass number = (number of protons) + (number of neutrons)

It is represented by the letter A.

<h3>Net charge</h3>

The net charge corresponds to the algebraic sum of all the charges that a atom possesses.

<h3>This case</h3>

In this case, an element has:

  • 2 neutrons.
  • 2 electrons.
  • 2 protons.

Then, the net charge is calculated as:

net charge= 2× 0 [charge of neutron] + 2× (+1) [charge of proton] + 2× (-1) [charge of electron]

<u><em>net charge= 0</em></u>

This element has no electrical charge, or net charge is zero. Then, the element is a neutral atom.

On the other hand, the mass number is the sum of the number of protons and the number of neutrons. So, in this case:

mass number= 2 protons + 2 neutrons

<u><em>mass number= 4</em></u>

Finally, the element is a neutral atom, with a net charge equal to zero and a mass number of 4.
