Answer:
The error would be $13.
Explanation:
Given data:
Actual payment = $325
estimated payment = $312
Error = ?
Solution:
Error = Estimated payment - Actual payment
Error = $312 - $325
Error = -$13
we can discard the negative sign and consider the absolute value. The error would be $13.
Answer: Theoretical yield is 313.6 g and the percent yield is, 91.8%
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of 
require 3 moles of 
Thus 2.8 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 mole of give = 2 moles of 
Thus 2.8 moles of give =
of
Mass of 
Theoretical yield of liquid iron = 313.6 g
Experimental yield = 288 g
Now we have to calculate the percent yield
Therefore, the percent yield is, 91.8%
Oxidation number is charge of element in compound. Can be neutral, positive or negative.
Oxygen in dichromate has oxidation number -2, becauce there are seven oxygens, net oxidation number of oxygen is -14.
2·x(oxidation number of Cr) + 7· (-2) = -2 2x= +12
x= +6, oxidation number of one chromium is +6.
Answer:
When you mix the sugar into the tea and stir, it dissolves so you can't see it. Also when you stir the sugar into the tea the taste changes and it turns sweeter.
