Write down four fuctions of water learned in life sciences class​

See explanation

Explanation:

Water is a polar solvent and is also called a universal solvent because of its ability to dissolve several substances especially in the body.

The functions of water learned in the life sciences class include;

1. Water is the medium for biochemical reactions

2. Most substances in the body are transported from place to place by water.

3. Water acts a solvent for many biologically important substances in the body.

4. Water is necessary in helping animals to regulate their body temperature.

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"
