Chemistry: counting atoms in compounds worksheet #7.0.1
Answer please!!!!!

Answers

Answer 1

Answer:

Atom is the most basic unit of matter. They are the general term used to describe pieces of matter. But a different kind of atom makes up an element. A combination of atom of different elements creates a molecule. For example, you have water; it has a chemical formula of H2O. If you separate H from O, you have two atoms. Two atoms for hydrogen and one atom for oxygen. However, they are of different elements. And when you combine them to form H2O, you create a molecule.

Answer 2

Answer:

In the given query, the total number of atoms present in the given chemical compound $\rm KMnO_4$ is six atoms total in number.

Compounds were formed when two atoms combine together by sharing electrons among themselves.

In the compound $\rm KMnO_4$ : It contains 1 K (Potassium atom), 1 Mn (Manganese atom) and 4O (Oxygen atom).

That means the compound contains total of six atoms in it.

Therefore, there are six atoms total in number present in the given compound $\rm KMnO_4$ .

What are the functions of ATP

Answers

Answer:

ATP acts as source of energy in several cellular and physical processes happening within the body.

Explanation:

The major functions of Adenosine Tri Phosphate (ATP) are –

a) ATP provides energy for cellular metabolic processes.

b) ATP assists in active transportation of macromolecules across the cell against the concentration gradient.

c) ATP functions in both extra and intracellular signaling by releasing itself from synapses and thereby modulates calcium and cyclic AMP level inside the cell.

d) Maintain the structure of the cell

e) Provides energy for muscle contraction by binding to the myosin

Answers

The attorney is incorrect. Anyone with type A or B can give birth to a child with Type O, since the O gene is recessive. It is highly possible that Mr. Johnson can be A(O) Type blood and "Mrs. Johnson" can be either A(O) or B(O) type. Both parents could have given their child O genes causing the child to be Type O.

Answers

Answer:

During inspiration or inhalation air moves from the larynx to trachea.

Explanation:

Respiratory pathway during inhalation of air:

Nostrils - nasopharynx - larynx - trachea (through glottis) - bronchi - bronchioles - alveoli.

Its alveoli where the actual exchange of gases take place. Alveoli is thin walled and vascular.

What is slowed when water is a limiting factor in an environment?
a. amount of evaporation
b. population growth
c. the types of rocks

Answers

Oxygen makes up 20% of the atmosphere while nitrogen makes up 78%. The other two percent is made up of other gases. Population growth would slow. Organisms need water to survive and if there is a limited amount of water, populations will decline.
