First I would have a pot of soil and a carrot (without fertilizer) then a pot of soli ,with fertilizer and a carrot. Then I would watch them for the same amount of time and identify weather the soil impacted the decomposition of the carrot and repeat this twice.
Same size pots
Same size carrots
Same soil
Same growth area
THIS IS AN COMBINATION REACTION SO3 Combined with H2O to form Sulfuric acid
Part 1 : Answer is only B substance is soluble in water.
In this experiment undissolved mass of each substance was measured. According to the given data, undissolved mass of substance B at 20 °C is 10 g while A is 50 g. Since, the initial added mass of each substance is 50 g, we can see that substance A is not soluble in water since the undissolved mass is 50 g.
Part 2 : Substance A is not soluble in water and substance B is soluble in water.
According to the given data, the undissolved mass of substance A remains as same as initial added mass, 50 g throughout the temperature range from 20 ° to 80 °C. Hence, we can conclude that substance A is not soluble in water.
But, according to the data, undissolved mass of substance B at 20 °C is 10 g. That means, 40 g of substance B was dissolved in water. When the temperature increases the undissolved mass of substance B decreases. Hence, we can conclude that substance B is soluble in water and solubility increases with temperature.
