Which of the following variables should Sarah change from one group of chamomile to the next?

A. the location of the plants

B. the height of the plants

C. the type of plants

D. the amount of water she gives the plants

The answer is A

Explanation:

This question is asking for the INDEPENDENT VARIABLE in the experiment. The independent variable of an experiment is the variable that is changed or manipulated by the experimenter in order to bring about a response.

In this experiment where Sarah wants to know where in her garden chamomile plants would grow the best. She hypothesizes that chamomile will grow best in the corner of the garden that gets the most sunlight. However, to test this hypothesis, she decides to plant several groups of chamomile in her garden as an experiment. The variable that Sarah can change in the several groups of chamomile (independent variable) is the LOCATION OF THE PLANTS.

Note that, "where" is a question of location.

How many moles of NaF are produced in the resction between sodium bromide and calcium fluoride when 550 grams of sodium bromide

bija089 [108]

Answer: 5 moles of NaF would be produced when 550 grams of Sodium bromide are used.

Explanation:

From the question, the balanced chemical formula is illustrated below:

2NaBr + CaF2 → 2NaF + CaBr2

From the equation above;

Molecular mass of NaBr = 23 + 80 = 103g/ mol

Molecular mass of CaF2= 40+ (19×2)= 78g/ mol

Molecular mass of NaF = 23+19 = 42g/ mol

From the balanced chemical equation;

2 moles of NaBr reacted with 1mole of CaF to give 2 moles of NaF.

That is, 2 moles of NaBr= 2× 103 = 206g

2moles of NaF = 2×42= 84g

If 206g of NaBr yielded 84g of NaF

Therefore 550g of NaBr will yield Xg of NaF

X= 550×84/206

X= 224.27g of NaF

But 42g = 1 mole of NaF

Therefore 224.27g = X mole of NaF

X= 224.27 ×1/42

X is approximately 5moles.
