As the temperature of a liquid increases, its viscosity _____. increases stays the same decreases
2 answers:
Answer: Option (c) is the correct answer.
Explanation:
Viscosity is defined as the ability of a liquid to resist its flow. When a substance has high viscosity then it is known as a viscous substance.
For example, honey has high viscosity.
But when we increase the temperature then there occurs more number of collisions between the molecules. Due to this there will be increase in kinetic energy of the molecules and they will be able to move the fluid easily.
As, Kinetic energy =
Thus, we can conclude that as the temperature of a liquid increases, its viscosity decreases.

Answer: Balanced molecular equation :
Total ionic equation:
The net ionic equation:
Explanation:
Complete ionic equation : In complete ionic equation, all the substances that are strong electrolyte are present in an aqueous state as ions.
Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.
Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.
When sodium phosphate and zinc acetate then it gives zinc phosphate and sodium acetate as product.
The balanced molecular equation will be,
The total ionic equation in separated aqueous solution will be,
In this equation, and are the spectator ions.
By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.
The net ionic equation will be,
