Nitrogen will form an ionic bond
When potassium chromate dissolves in water, the ions that are produced are potassium and chromate.
This can be expressed as follows:
Potassium chromate in water will give the following ions:
<span>2K+ + CrO4^2- </span>
<span>Ultrafiltration is a process which prevents the dilution of the bloos. During this process some of water with some dissolved materials is forced </span>through the membrane by maintaining the blood at a higher pressure than the solution.
From the information we have, this block of brown sugar has a volume of 8cm3
The mass of the block is 12. 9 grams.
We need to find out the density of the sugar.
For a solid material the formula for calculating density is given as:
Density = mass / volume
Therefore we simply fit in the above given values into this formula, so:
Density = 12.9 / 8
Density = 1.61
Therefore the density of the block of sugar is 1.61g/ml
