Explanation:

All the atoms present in periodic table are neutral in nature and it is known that a neutral atom means that it contains no charge.

For example, sodium is present as Na in the periodic table. And, it does not contain any charge.

When a neutral atom loses or gains an electron then it acquires a charge.

For example, atomic number of calcium is 20 and its electronic distribution is 2, 8, 8, 2. Hence, in order to acquire stability when it loses 2 valence electrons then neutral atom of Ca changes into $Ca^{2+}$ .

Hence, it means that by loosing 2 valence electrons calcium has an electric charge of +2.

Answer:

Neutral

Explanation:

Atoms on the periodic table all have neutral electric charges. This is because they have an equal number of protons, which are positivly charged, and electrons, which are negatively charged.

The diagram shows a simple lipid.

kifflom [539]

This is not a phospholipid as it does not contain a phosphate group at the end of the chain, and is not a triglyceride as there is no glyceryl moiety. Each carbon bonded to hydrogens makes the maximum number of C-H bonds possible, therefore there are no multiple bonds between carbons and the lipid is saturated. Therefore the answer is A.
Hope this helps!

What type of organic compound has the empirical formula CH2O and can serve as energy storage or the starting material for fats a

Luda [366]

Carbohydrates. CH2O is the most basic formula of simple sugars.Empirical formula is the lowest whole number ratio of atoms in a formula.For example glucose is C6H12O6 can be reduced by 6 to get CH2O. Simples sugars include glucose and fructose which can serve as sources of energy for fats and amino acids.

If you had continued following the water molecule in the Water Cycle Activity, what step do you predict would have occurred next

tamaranim1 [39]

Answer:option D is the correct answer, precipitation and it is because water is being released from the cloud into the earth.

Explanation:

PRECIPITATION is the process by which water condenses in the atmosphere. Precipitation can occur in form of snow,fog, dew,rain etc.

Atmospheric water is found in clouds and water vapor. Gradually and systematically the entire atmosphere rotates around the planet. When weather is being formed one of the most common results is precipitation.

In the water molecule activity here, precipitation will occur because water is being released from the atmosphere into the earth.
