Question

The NaHCO3 is the limiting reactant and the HCl is the excess reactant in this experiment. Determine the theoretical yield of the NaCl product, showing all of your work in the space below.

Answer 1

use the moles of the limiting reactant to find the moles of NaCl with a ratio of their coefficients (from the balanced reaction). Set it up like this:

\(\dfrac{moles~of~NaHCO_3}{NaHCO_3's~ coefficient}=\dfrac{moles~of~NaCl}{NaCl's ~coefficient}\)

then solve for moles of NaCl, like algebra. For example,
\(\dfrac{2}{3}=\dfrac{x}{4}\rightarrow x=\dfrac{4*2}{3}\)

Answer 2

How do I find the moles

Answer 3

mole= mass/ Mr

Answer 4

u have masses so find Mr of each solution then use that formula

Answer 5

What's mr?

Answer 6

molar mass

Answer 7

Okay so how do find that

Answer 8

ok look u have ur periodic table ryt?

Answer 9

yeah

Answer 10

NaHCO3
so from periodic table find masses of Na, H, C, O
then add them up, since there are 3 oxygens that means that mass *3 and only then add those numbers up

Answer 11

do same thing with HCl

Answer 12

make sure to subtract mass of the dish from ur given values

Answer 13

Is molar mass the same thing as mass?

Answer 14

not really, molar mass is in amu

Answer 15

sorry i can explain all the work in steps to make it easy for you, but im outside right now, i'll be back only like in 3-4 hours T_T
