Answer:
C3H6O
Explanation:
The percentage composition of the elements in the compound are given as follows:
62.1 % carbon = 62.1g of C
10.5 % hydrogen = 10.5g of H
27.6 % oxygen = 27.6g of O
Next, we convert each mass to mole by dividing by their molar/atomic mass
C = 62.1/12 = 5.175mol
H = 10.5/1 = 10.5mol
O = 27.6/16 = 1.725mol
Next, we divide each mole value by the smallest mole value (1.725)
C = 5.175mol ÷ 1.725 = 3
H = 10.5mol ÷ 1.725 = 6.086
O = 1.725mol ÷ 1.725 = 1
The empirical ratio approximately of C:H:O is 3:6:1, hence, the empirical formula is C3H6O
Answer:
Oxygen gas
Explanation:
Potassium chlorate KClO3 decomposes thermally to form potassium chloride KCl and oxygen gas is given off. This is in the presence of a catalyst, manganese iv oxide.
Hence, what is being said in essence is that when potassium chloride is heated in the presence of manganese iv oxide catalyst, oxygen is given off as the gaseous product with the formation of potassium chloride.
The chemical equation for the reaction is :
2KClO3 ——-> 2KCl + 3O2
This procedure is one of most important ways through which oxygen can be produced in the laboratory and can be used as a source of oxygen is industrial processes if on a large scale
Answer: NADH
Explanation:
In both of the processes the electron acceptor is NADH which accepts the electrons. Glycolysis takes place in the cytoplasm of the cell.
In case of glycolysis the NADH accepts the electrons when the Glyceraldehydyde 3-phosphate is converted into 1, 3 Biphosphoglyceric acid. In the last step of the glycolysis 4 ATP molecules are produced.
Kreb's Cycle takes place in the mitochondria of the cell. During this process the electron acceptor is NADH. 3 molecules of NADH is produced during the process of citric acid cycle.
During the step when the isocitrate is converted into alphaketogluterate , alphaketogluterate is converted into succinyl co A and malate to oxaloacetate produces 1 molecules of NADH at each step.
