Here’s the answers I wasn’t asking a question hehe!Subtract the mass of the filter paper (0.27g) from the mass of the paper and
copper (0.98 g). Record the difference in the data table as the amount of copper.
You already converted mass to moles for the reactants. Now convert mass to moles for the product, copper
all for edge

Answer:
Explanation:
From the given information, since the molecular mass of the ion M+ is not given;
Let's assume M+ = 58.0423
So, by applying the 13th rule;
we will need to divide the mass by 13, after dividing it;
The quotient n = no. of carbon; &
The addition of the quotient (n) with the remainder r = no. of hydrogen.
So;
So;
From the given information; we have oxygen present, so since the mass of oxygen = 16, we put oxygen in the molecular formula by removing . Also, since the mass is an even number then Nitrogen is 0.
So, we have:
<u>Answer:</u> The value of for
reaction is
<u>Explanation:</u>
We are given:
Initial moles of nitrogen gas = 1.30 moles
Initial moles of hydrogen gas = 1.65 moles
Equilibrium moles of ammonia = 0.100 moles
Volume of the container = 1.00 L
For the given chemical equation:
<u>Initial:</u> 1.30 1.65
<u>At eqllm:</u> 1.30-x 1.65-3x 2x
Evaluating the value of 'x'
The expression of for above equation follows:
Equilibrium moles of nitrogen gas =
Equilibrium moles of hydrogen gas =
Putting values in above expression, we get:
Calculating the for the given chemical equation:
Hence, the value of for
reaction is
