A) When the moon is full
Explanation:
The moon controls the tides, so the more the moon the more the tide
Answer:
True
Explanation:
The percentage yield of a reaction , is given by the formula -
Percentage yield = (actual yield)/(theoretical yield) * 100
Actual yield = the exact amount of yield obtained from an experiment
Theoretical yield = the calculated yield of the experiment.
The denominator value i.e. theoretical yield can never exceed the numerator value , i.e. the actual yield ,
Hence,
percentage yield can never be more than 100% .
Answer:
b) 49.48% C, 5.19% H, 28.85% N, and 16.48% O
Explanation:
According to this question, caffeine has a molecular formula of C8H10N4O2. In order to find the percentage composition of each element in this compound, we must first find the molar mass of the compound:
C8H10N4O2
Where; C = 12, H = 1, N = 14, O = 16
12(8) + 1(10) + 14(4) + 16(2)
96 + 10 + 56 + 32
194g/mol
Next, we find the percent composition of each element as follows by dividing mass of each element by molar mass of the compound and multiplying by 100
C = 96/194 × 100 = 49.48%
H = 10/194 × 100 = 5.15%
N = 56/194 × 100 = 28.86%
O = 32/194 × 100 = 16.49%
