In the case of phylogeny, evolutionary investigations focus on two types of evidence: morphologic (form and function) and genetic.

The graph below shows how solubility changes with temperature.

Otrada [13]

The two solutions that have similar solubilities at 40°C will be Na₂HAsO₄ and Na₂SO₄.

<h3>What is solubity ?</h3>

It is the ability of a solute to be dissolved, especially in water.

As the temperature increases the solubility of the gas generally decreases"

According to given information and graph attached as reference ;

Solubility of NaCl (sodium chloride) at 40°C is 36.3 grams.
Solubility of Na₂SO₄ (sodium sulfate) at 40°C is 48.8 grams.
Solubility of Na₂HAsO₄ (sodium arsenate dibasic) at 40°C is 48.9
grams.
Solubility of Ba(NO₃)₂ (barium nitrate) at 40°C is 14.1 grams.

Compound AB decomposes into elements A and B by the following reaction: AB →A + B. If you produce 10.00 g of B and 3.00 g of A,

zavuch27 [327]

Answer:

13.00 g

Explanation:

To solve this problem, you need to understand the law of conservation of mass. This law means that whatever amount you start out with is what you should have at the end. The amount may be in different forms, but that amount is still there.

If you produced 10.00 g of B and 3.00 g of A, you should have started out with 13.00 g of AB.

10.00 + 3.00 = 13.00
