A 0.85% saline solution is: a.8.5 mL of saline added to 91.5 mL of water b.85 g of NaCl made up to 1,000 mL of water c.0.85 g NaCl made up to 100 mL of water d.8.5 g NaCl in 100 mL of water

c

Explanation:

A 0.85% saline solution would consist of 0.85 g NaCl made up to 100 mL of water.

A 0.85% saline solution contains 0.85% by weight of NaCl. Hence, in order to prepare such a solution, 0.85 g of NaCl is weighed out into a beaker or cylinder and distilled water is added up to the 100 mL mark. On the other hand, 8.5 g of the NaCl can be weighed out and then distilled water added to 1000 mL mark.

The correct option is, therefore, c.

clouds form

solid ice forms on leaves.

water droplets form on grass.

the answer is barium and copper bromide
