CO isn’t a compound so it’s D
Answer: 11.25 moles of 
will be required to completely react with 2.25 moles of 
.
Explanation:
The balanced chemical equation is:
According to stoichiometry :
1 mole of require = 5 moles of
Thus 2.25 moles of will require=
of
Thus 11.25 moles of will be required to completely react with 2.25 moles of .
Answer:
<h2>30.2 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
volume = final volume of water - initial volume of water
From the question
volume = 35.9 ml - 25.8 ml = 10.1 mL
We have
mass = 2.99 × 10.1 = 30.199 g
We have the final answer as
<h3>30.2 g</h3>
Hope this helps you
Answer:
B.Handling the crucible directly with your hands.
D.Taking the mass of the empty crucible without the lid, but including the lid in all other mass measurements.
E.Taking the mass of all samples with the lid included.
Explanation:
When observed critically , the measures associated with the errors which could cause your percent yield to be falsely high, or even over 100% are those which increase the weight of the substance with the individual neglecting.
Handling the crucible directly with your hands,Taking the mass of the empty crucible without the lid, but including the lid in all other mass measurements and taking the mass of all samples with the lid included will all increase the weight of the substance. Instead the substance should be placed alone without any form of support or contamination.
