Quick! question 10
in a chemical reaction, how does the total mass of the products compare to the total mass of the reactants

The answer is A, they are always equal.

As seen in the Law of Conservation of Mass/Energy, Matter can be neither created nor destroyed. You can't get more matter through a reaction just as you can't make that matter simply disappear. Because atoms are only rearranged in a chemical reaction, there must be the same number of atoms in both the reactants and the products.

I hope this helps you out! Good luck!

c is the correct answer hope this !

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
