Answer:
ΔH°rxn = -47 kJ
Explanation:
Using Hess´s law for the reaction:
3 Fe2O3(s) + CO(g) → 2 Fe3O4(s) + CO2(g) ,
the ΔH°rxn will be given by the expression:
ΔH°rxn kJ = 2ΔHºf(Fe3O4) + ΔHºf(CO2) - ( 3ΔHºf(Fe2O3) + ΔHºf(CO) )
= 2(-1118) + (-394) - ( 3( -824 ) + ( -111 ) )
= - 47 kJ

Answer:Basic
Explanation:
The pH value of the acid is 10.0 which falls within the range of basic substances. A neutral substance has a pH of 7. Any substance with pH greater than 7 is basic while pH less than 7 is for Acidic
Answer:
<h3>The answer is 1.63 %</h3>
Explanation:
The percentage error of a certain measurement can be found by using the formula

From the question
actual mass = 9.80 g
error = 9.80 - 9.64 = 0.16
We have

We have the final answer as
<h3>1.63 %</h3>
Hope this helps you
