First of all, it is a nucleic acid, not nuclear acid.
Examples are DNA and RNA( Deoxyribonucleic Acid and Ribonucleic Acid)
Answer:
Picture D represents the only possible option as the Picture D rearranges the atoms whereas A, B, and C did not. Option D
Explanation:
We can see in the pictures A, B and C the atoms are not arranged properly if we keep the fundamental image in view. By comparing all the images you will observe how the atoms in the fundamental image are differently represented in image A, B and C. Also the fundamental image have 10 atoms whereas all the option except D varies the number of atoms
Answer:
a) 40 %
b)
c)
Explanation:
For a) we will have to calculate the <u>molar mass</u> of , so the first step is to find the <u>atomic mass</u> of each atom and multiply by the <u>amount of atoms</u> in the molecule.
C => 12*(6) = 72
H => 1*(12) = 12
O => 6*(16) = 96
Molar mass = 180 g/mol
Then we can calculate the percentage by mass:
For b) we have to start with the <u>reaction of glucose</u>:
Then we have to convert the grams of glucose to moles, the moles of glucose to moles of carbon dioxide and finally the moles of carbon dioxide to grams. To do this we have to take into account the<u> following conversion ratios</u>:
-) 180 g of glucose = 1 mol glucose
-) 1 mol glucose = 6 mol carbon dioxide
-) 1 mol carbon dioxide = 44 g carbon dioxide
For C, we have to start with the conversion from grams of glucose to moles, the moles of glucose to moles of oxygen and finally the moles of oxygen to molecules. To do this we have to take into account the <u>following conversion ratios</u>:
-) 180 g of glucose = 1 mol glucose
-) 1 mol glucose = 6 mol oxygen
-) 1 mol oxygen = 6.023x10^23 molecules of O2
