Adrian is a researcher who works in a lab. he decides to perform an experiment to understand the side effects and benefits of drinking tea. he puts forth some questions about the experiment. they include, do people who drink tea have a higher risk of brain illnesses than non-tea drinkers? and do people who drink tea stay more alert than non-tea drinkers? he also proposes a question, are people who drink tea happier than people who don't drink tea?

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

the correct answer is c
