A mixture of sand and table salt can be separated by filtration because the substances in the mixture differ in solubility. Because sand and table salt have a different ability to dissolve they can easily be separated. What can be done to separate this mixture is to add water to it and stir it thoroughly. The salt will easily dissolve in water while the sand will stay insoluble. The filtration of this mixture will result in salt being drained off with water while only the sand will remain.

The frequency of collisions between the N₂ and H₂ molecules will decrease and the rate of reaction will also decrease.

Since the water is cooler than the gas mixture, heat will flow from the gas to the water.

The gas will cool down, so the average kinetic energy of the gas molecules will decrease.

The molecules will be moving more slowly, so there will be fewer collisions and fewer of these collisions will have enough energy to react.

The rate of reaction between H₂ and N₂ molecules at room temperature is exceedingly slow, but cooling the gas mixture will make the reaction even slower.

Answer:

SO4 (aq) + Sr (aq) >> SrSO4 (s)

Explanation:

K+1 SO4-2 + Sr +2 I2- >> sK +1

(you dont separate and write down the ions for Sr SO4 because its a solid)

Cancel out the same ions from both sides and write down what your left with.
