Answer:

A compound is a unique substance that forms when two or more elements combine chemically. Compounds form as a result of chemical reactions. The elements in compounds are held together by chemical bonds. A chemical bond is a force of attraction between atoms or ions that share or transfer valence electrons

Answer:

Explanation:

When 2 or more elements combine a compound stats to form. These are held together with a very strong chemical bond (which can vary depends on the elements). This chemical bond makes all of these little ions come to it and thats how a chemical reaction is made.

Controls senses and most body functions .

Carries message and information between the brain & body​

Explanation:

The nervous system helps to control senses, body functions, carries message and information between brain and the body. It consists of the brain, spinal cord and the nerves.

  • Using series of electrical nerve impulses, the nervous system controls the body administration.
  • The brain, spinal cord and nerves directs communications between different parts of the body system.
  • It is divided into two broad categories, the central nervous system which consists of the brain and spinal cord and the peripheral nervous system which is made up the nerves.

A student takes a measured volume of 3.00 M HCl to prepare a 50.0 mL sample of 1.80 M HCI. What volume of 3.00 M HCI
frozen [14]

Answer:

30 mL VOLUME OF 3.0 M HCl SHOULD BE USED BY THE STUDENT TO MAKE A 1.80 M IN 50 mL OF HCl.

Explanation:

M1 = 3.00 M

M2 = 1.80 M

V2 = 50 .0 mL = 50 /1000 L = 0.05 L

V1 = unknown

In solving this question, we know that number of moles of a solution is equal to the molar concentration multiplied by the volume. To compare two samples, we equate both number of moles and substitute for the required component.

So we use the equation:

                                  M1 V1 = M2 V2

V1 = M2 V2 / M1

V2 = 1.80 * 0.05 / 3.0

V2 = 0.09 /3.0

V2 = 0.03 L or 30 mL

To prepare the sample of 1.80 M HCl in 50.0 mL from a 3.0 M HCl, 30 mL volume should be used.
