Chemistry
2 answers:
shutvik [7]3 years ago
7 0

Answer:

\boxed{Heptene}

Explanation:

Double Bond => An Alkene molecule

So, the suffix will be "-ene"

7 Carbons => So, we'll use the prefix "Hept-"

Combining the suffix and prefix, we get:

=> Heptene

Answer:

\boxed{\mathrm{Heptene}}

Explanation:

Alkenes have double bonds. The molecule has one double bond.

Suffix ⇒ <em>ene</em>

The molecule has 7 carbon atoms and 14 hydrogen atoms.

Prefix ⇒ <em>Hept </em>(7 carbons)

The molecule is Heptene.

\mathrm{C_7H_{14}}

Question 20 (2 points)
sveta [45]

Answer:

becomes runoff and finds its way back to the ocean

Explanation:

Precipitation refers to rainfall that reaches the earth.

Most of the rainfall that reaches the earth becomes runoff and finds its way back to the ocean.

When the rain falls on earth, some evaporates, some enters into the ground while some runs off into rivers and streams. Almost all of the rain water flows into the oceans or other bodies of water.

Hence, most of the rainfall that reaches the earth becomes runoff and finds its way back to the ocean

Which statement is true about AC?
AysviL [449]

According to the research, the correct option is A. The electrons move back and forth is the statement that is true about AC.

<h3>What is AC?</h3>

It is the flow of electric charges through a conductor is called electric current, if said flow of electric current varies in direction from time to time, we speak of alternating current.

Subatomic particles such as protons and electrons have an electrical charge, a physical property that is manifested by the repulsive and attractive forces that exist between them in AC the electrical charge moves back and forth.

Therefore, we can conclude that according to the research, the correct option is A. The electrons move back and forth is the statement that is true about AC.

Explain how to convert a mass of compound A to a mass of compound D in words with no equations using the following reaction 2A +
leonid [27]

Answer:

Explanation:

The given reaction equation is:

                2A + 4B → C + 3D

We know the mass of compound A in the reaction above. We are to find the mass of compound D.

We simply work from the known mass to calculate the mass of the unkown compound D

Using the mole concept, we can find the unknown mass.

Procedures

  • We first find the molar mass of the compound A from the atomic units of the constituent elements.
  • We then use the molar mass of A to calculate its number of moles using the expression below:  

            Number of moles of A = \frac{mass of A}{molar mass of A}

  • Using the known number of moles of A, we can work out the number of moles of D.

           From the balanced equation of the reaction, it is shown that:

         2 moles of compound A was used up to produced 3 moles of D

  Then \frac{3}{2} x number of moles of A would give the number of moles of D

  • Now that we know the number of moles of D, we can find its mass using the expression below:

             Mass of D = number of moles of D x molar mass of D
