The chemical reaction would be as follows:
<span>2Na + S → Na2S
We are given the amount of the reactants to be used in the reaction. We use these to calculate the amount of product. We do as follows:
45.3 g Na ( 1 mol / 22.99 g ) = 1.97 mol Na
105 g S ( 1 mol / 32.06 g ) = 3.28 mol S
The limiting reactant would be Na. We calculate as follows:
1.97 mol Na ( 1 mol Na2S / 2 mol Na ) (78.04 g / mol ) = 76.87 g Na2S produced</span>
About 5 millimeters which weighs about 5 grams. Hope this helps! ^-^
Answer:
0.05263158 atm
Explanation: mmHg to Atmosphere Conversion Example. Task: Convert 975 mmHg to atmospheres (show work) Formula: mmHg ÷ 760 = atm Calculations: 975 mmHg ÷ 760 = 1.28289474 atm Result: 975 mmHg is equal to 1.28289474 atm. This is an example for how i got the answer.
Hey there!:
Amount of purified acid phosphatase added to tube A = 5 ug ( micrograms )
Amount of acid phosphatase present in 400 ug of wheat germ extract in tube B :
1 / 100 = 5x / 400 =
100 x = ( 0.5 ) ( 400 ) =
x = (0.5 ) ( 400 ) = 100
x = 200 / 100
x = 2 ug
The amount of acid phosphatase present in 400 ug of the wheat germ in tube B is 2 ug
Hope that helps!
