If the colored spheres are solutes, the overall direction of water would be out of the cell based on the principle of osmosis.

<h3>What is osmosis</h3>

It is the movement of water molecules from the region of high water potential (low solutes) to the region of low water potential (high solute) through a selectively permeable membrane.

In the illustration, there are more colored spheres outside of the cell than inside of it. This means that there are more solutes outside the cell (lower water potential) than inside of the cell (higher water potential).

Thus, water will move from the inside of the cell to the outside until an equilibrium is established.

Why is there more co2 in the air that you breathe out than in the air that you inhale?

larisa [96]

CO2 is produced during respiration by mitochondria.
To know why there is more CO2 in the air that you breathe out than the CO2 which you inhale, we have to know that the carbon which we breathe out as carbon dioxide comes from the waste products (the carbon in the food we eat) like the carbohydrates, fat, and protein which converted in the body by biochemical pathways to glucose. the end products of oxidation of glucose are water and carbon dioxide. This carbon dioxide which dissolved in the human blood is carried to the air in the lung by circulation before it exhales.

The Coefficients will be :

$NaBr - 3$

$H_3PO_4 - 1$

$Na_3PO_4 - 1$

$HBr - 3$

So, Correct option is :

A. 3, 1, 1, 3

Draw the addition product formed when one equivalent of hcl reacts with the following diene.

pashok25 [27]

Answer:

Major Product = 4-chloro-4-methylcyclohex-1-ene

Explanation:

Alkene are the class of organic compounds which contain one or more double bonds between two carbon atoms. Alkenes are considered most reactive among the unsaturated hydrocarbons and they undergo <em>addition reactions</em> due to high electron density around the double bonds.

In given question it is written that we are provided with one equivalent of HCl while, our compound contains two double bonds (diene) so in selected starting material the HCl will be added across (hydrohalogenation reaction) the substituted double bond because it will give a more stable carbocation (<u><em>tertiary carbocation</em></u>) during the reaction course. Hence, as shown in reaction scheme 4-chloro-4-methylcyclohex-1-ene will be the major product.
