Determine the correct set-up below to determine what mass, in grams, of N2 is needed to completely react with 105 g F2 ?

Answers

Answer 1

Answer:

C: 1 mol F2/38 g F2

Explanation:

The reaction equation is;

N2 + 3F2 = 2NF3

Now, to know how many grams, of N2 is needed to completely react with 105 g F2 and since the molar mass of N2 is 28.02 g/mol, Molar mass of F2 is 38 g/mol, number of moles attached to N2 and F2 in the reaction are 1 and 3 moles respectively, then we will have;

105 g F2 × 1 mol F2/38 g F2 × 1 mol N2/3 mol F2 × 28.02 g N2/1 mol N2

Option C is Thus correct

b
nonmetals are more reactive than metals
c
metals are brittle and dull
d
metals have high melting points and are malleable, whereas, nonmetals have lower melting points and tend to be brittle.

Answers

Answer:

the answer is d.

Explanation:

because metals are refers to natural elements that are hard, shiney, opaque, and dense. nonmetals implies thise chemical substances that are soft, non-shiney, transparent and brittle.

What is the molecular formula for a compound that is 34.31% sodium, 17.93% carbon, 47.76% oxygen and has a molar mass of 134.00g?

Answers

Answer: Na2C2O4 probably sodium oxalate

Explanation: assume you have 100 g substance.

Mass of Na is m(Na) = 34.31 g, m(C) = 17.93 g and m(O) = 47.76 g.

Calculate moles n(Na) = 34.31 g/22.99 g/mol= 1.49 mol.

For C n(C) = 1.49 mol and n(O) = 2.985. You divide all by 1.49 you

Get n(Na) : n(C) : n(O) = 1:1:2 M(NaCO2) = 67 g/mol.

Divide 134:67 = 2. You get formula Na2C2O4

So, as a first step, you need to find AC(Q) from C(Q). In part (a), finding min AC(Q) is easy and you should be able to do so just by looking at the formula for AC (Q).
