Answer: A. O2
Explanation:
If photosynthesizing green algae are provided with CO2 containing heavy oxygen (18O), subsequent analysis will show that 18O first appears then 3-phosphoglycerate molecule produced by the algae.
Answer:
9.7 g
Explanation:
From the question,
Note: The molar volume of all gas at stp is 22.4 dm³ or 22.4 L
1 mol of oxygen gas (O₂) at stp = 22.4 dm³
X mole of oxygen gas (O₂) at stp = 6.8 L
X = (1 mol×6.8 L)/22.4 L
X = 0.3036 mol.
But,
Number of mole (n) = mass (m)/molar mass (m')
n = m/m'
m = n×m'.................. Equation 2
Where n = 0.3036 mol, m' = 32 g/mol
Substitute into equation 2
m = 0.3036×32
m = 9.7 g
Answer:
N is single bonded to R, and single bonded twice to H.
Explanation:
The functional group present in an amine will not be complete without mentioning the nitrogen group present in the compound.
Amines are organic compounds that show appreciable basicity. They are regarded as the derivatives of ammonia where one or two or the three hydrogen atoms has/have been replaced been replaced by alkyl or aryl groups.
- Amines are classified as primary, secondary or tertiary based on the number of substituted hydrogen atoms they carry.
- The nitrogen bonded to the R - aryl group and bonded to hydrogen is a good description of the functional group.

If one does not do so, the cut can lead to being infected with various pathogens and other Bacteria, possibly worsening the Minor injury. Thus taking additional medication and further required time to heal.
