During the cold winter months the surface Of a lake becomes hard Ice this is due to which change of state
nikitadnepr [17]

Freezing

Explanation:

This change in state when surface of a lake changes to hard ice is known as freezing.

  • When a solid is heated, it melts and changes to a liquid. On further heating, it changes to vapor and the randomness increases.
  • When a liquid is cooled below its freezing point, it changes to a solid such as ice for water.
  • The phase change is known as freezing.

What is the molarity of NO−3 in 0.160M KNO3?
zubka84 [21]
A solution of KNO3 consists of ions of potassium and nitrate. The ionic equation is expressed as:

KNO3 = K+ + NO3-

There is 1 is to 1 ratio between the substances. So, the molarity of NO3- in the solution is calculated as follows:

0.160 mol / L KNO3 ( 1 mol NO3- / 1 mol KNO3 ) = 0.160 M NO3-
