Explanation:
The term IHD means index of hydrogen deficiency. It tells us the number of missing hydrogen atoms from a given chemical formula. This number of missing hydrogen atoms corresponds to the number and type of multiple bonds in a given compound.
The formula for IHD is; IHD = C + 1 + N/2 – H/2 – X/2
C = Number of carbon atoms
N = Number of nitrogen atoms
H = Number of hydrogen atoms
X = Number of halogen atoms
Since;
N=0, X=0
Then;
IHD = C + 1 – H/2
Hence;
IHD = 6 + 1 - 14/2
IHD = 7 -7
IHD = 0
An IHD of 0 implies that there is no hydrogen deficiency or multiple bond in the molecule. It is purely a saturated compound.
Recall that the main function of chloroplasts is to convert sunlight to chemical energy, or to carry out photosynthesis. Plant (and eukaryotic algae) cells contain these organelles, while animal cells do not, and hence, animals cannot carry out photosynthesis.
So, a lack of chloroplasts would mean that an organism would not be able to convert sunlight into chemical energy through photosynthesis.
Plants cells, and specifically the chloroplast organelle, are able to absorb sunlight, and together with CO₂ and water, produce glucose (for the plant to eat) and oxygen (which is released into the atmosphere). That glucose is further broken down by the plants' mitochondria. Animals directly consume the glucose to be broken down and converted into energy, hence why we do not have - nor need - chloroplasts in our cells.
Answer:
Element X has valency 2 while Y Valency 2, element Y has high tendency of gaining electrons for its stability thus the compound formed will be B
elements X is positively charged while Y will be negatively charged
Answer:
Aluminum, boron, and gallium are likely together in one group because they have the same number of valence electrons, and carbon and germanium are likely together in another group because they have the same number of valence electrons.

Answer:
Love is an emotion you feel for someone or something very closely and enjoy spending time with them. Love can be a good thing and bad. It can be bad by being rejected by the person you like or even love. After that you might say you never want love again. But without love you might not be the person you are now. You now might know your mistakes and will do better the next time. Without love you won't have any cherishful moments. You might even turn depressed. But the past is the past, and you must look forward.
