Answer:
749 grams CO₂
Explanation:
To find the amount of carbon dioxide produced, you need to (1) convert grams C₃H₈ to moles C₃H₈ (via molar mass from periodic table), then (2) convert moles C₃H₈ to moles CO₂ (via mole-to-mole ratio via reaction coefficients), and then (3) convert moles CO₂ to grams CO₂ (via molar mass from periodic table). It is important to arrange the ratios/conversions in a way that allows for the cancellation of units. The desired unit should be in the numerator. The final answer should have 3 significant figures because the given value (250. grams) has 3 sig figs.
Molar Mass (C₃H₈): 3(12.01 g/mol) + 8(1.008 g/mol)
Molar Mass (C₃H₈): 44.094 g/mol
1 C₃H₈ + 5 O₂ ---> 3 CO₂ + 4 H₂O
Molar Mass (CO₂): 12.01 g/mol + 2(16.00 g/mol)
Molar Mass (CO₂): 44.01 g/mol
250. g C₃H₈ 1 mole C₃H₈ 3 moles CO₂ 44.01 g
------------------ x ---------------------- x ---------------------- x -------------------- =
44.094 g 1 mole C₃H₈ 1 mole CO₂
= 749 grams CO₂
well one thing that’s unique about water is the fact that it’s dipole, meaning that water has both a positive side and a negative side.
Answer: The average rate of the reaction during this time interval is, 0.005 M/s
Explanation:
The given chemical reaction is:
The expression will be:
where,
= final concentration of 
= 0.025 M
= initial concentration of = 0.100 M
= final time = 15 minutes
= initial time = 0 minutes
Putting values in above equation, we get:
Hence, the average rate of the reaction during this time interval is, 0.005 M/s
The
functional group found in an ester is a carbonyl group with an attached second oxygen
atom that is bonded to a carbonyl carbon substituent by a single bond, usually
a pair of alkyl or aromatic groups. In addition, it can be shown in
text as RCOOR or occasionally as ROCOR, which made them responsible in the <span>distinctive and attractive
odors and flavors of many flowers, perfumes, and ripe fruits. </span>
