What is the completed equation: c3h6+br2->
in chemistry.

Explanation:

First of all, we need to understand that propene, , is an alkene. This can easily be understood from the general formula of alkenes having an expression of . This means when you spot a formula with twice as many hydrogen atoms as carbon atoms, you will have an alkene (or a cycloalkane, but no reaction would take place with a cycloalkane).

Alkenes have a double bond and they produce an addition reaction with bromine water. The evidence for this experimentally is when you mix an alkene with bromine water, the color of the solution disappears.

The two bromine atoms are joined to the two carbons forming a double bond by removing the pi bond and making a saturated molecule with single bonds only. That said, we have a simple addition reaction in which the bromine atoms are added to the molecule.

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.

which of the following is most likely to happen if a cell is not able to divide?

the cell will not be replaced when it is damaged.

explanation:

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
