Answer: There was a lower concentration of salt in the water than in the cells.

Explanation:

Osmosis is a process in which the solvent flow from a solution of low concentration to a solution of high concentration through a semi-permeable membrane.

When the red blood cells are put in water that contained salt and the red blood cells burst after some time.

This means the solvent has moved from outside to inside the cell and this is possible only when the concentration of solute is high inside the cell than outside. That means the solution has low concentration of solute as compared to the cell and was a hypotonic solution.

2.24g of iron combine with 0.96g of oxygen to form an oxide of iron. Determine the formula of this oxide of iron and use it to c

irakobra [83]

Answer:

See Explanation

Explanation:

Let us find the number of moles of each element

For iron = 2.24g/56 = 0.04 moles

For oxygen = 0.96 g/16 = 0.06 moles

Then we divide by the lowest ratio;

0.04/0.04 and 0.06/0.04

1 and 2

We Thus obtain 1 : 1.5

Multiplying through by 2 we have; 2 : 3

The formula of the oxide formed is Fe2O3

The balanced equation is;

4Fe + 3O2 ------> 2Fe2O3
