Susan said, "if I fertilize my geranium plants, they will blossom" Choose the correct step in the scientific method

A. recognize a problem
B. from hypothesis
C. test the hypothesis with an experiment
D. draw conclusions
​

This is called a hypothesis, which can be identified by the if... then... format.

So, the correct option is B. Form a hypothesis.

Let me know if this helps!

C

Explanation:

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
