A solution contains 35 grams of KNO3 dissolved in 100 grams of water at 40°C. How much more KNO3 would have to be added to make
Marta_Voda [28]

Answer:

32g

Explanation:

potassium nitrate has solubility of about 67g per 100g of water at 40°C, which means that potassium nitrate solution will contain 67g of dissolved salt for every 100g of water.

since at this temperature, our solution contains  35g of potassium nitrate 100g  of water. The solution will be unsaturated because of the less potassium nitrate.

to make saturated solution,

mass of potassuim nitrate = 67g - 35g

= 32g

which means dissolving another  32g  of potassium nitrate in solution at 40 °C will make saturated solution.

<h2>Answer:</h2>

The correct answer is option A which is hybridization occurs in plants more often than in animals.

<h3>Explanation:</h3>
  • Hybridization means mixing of different things.
  • In the context of biology, hybridization means the mixing of genetic material of the two dissimilar species. The resulting offspring is known as the hybrid.
  • In the case of animals, they are usually infertile as a mule, a hybrid of donkey and horse.
  • Hybridization always involves interspecies mating. And sometimes the natural selection is in favor of hybridization.
  • In plants, it is very common which is also known as crossbreeding and different types of plants and fruits are produced by this method.
  • Hence the correct option is A.
