Answer:
A) They get oxidized into carbon monoxide and carbon dioxide by the oxygen molecules generated on the electrode.
Explanation:
In the electrolysis of Aluminium, the oxygen reacts with the carbon anodes forming carbon dioxide. That is, the anodes are oxidized. To ensure that the reaction completes, the anode must gradually be replaced as the reaction proceeds. The correct option is hence;
A) They get oxidized into carbon monoxide and carbon dioxide by the oxygen molecules generated on the electrode.
Answer: 0.70g
The half-life of iron-53 would be 8.51 minutes. So, in 25.53 minutes would be equal to: 25.53 min/ (8.51 minutes/ half-life)= 3 half-life.
Every half-life will reduce the original weight into half. So, the final weight would be:
final weight = original weight * 1/2 ^(time)
final weight = 5.6g * (1/2)^(3 half-life)
final weight = 5.6g * 1/8= 0.7g
Answer:
The molecular formula of mono sodium glutamate is
Explanation:
Molar mass of sodium glutamate,M = 169 g/mol
let the molecular formula be
Percentage of carbon in the M.S.G. =35.52 %
a = 5
Percentage of Hydrogen in the M.S.G. = 4.77 %
b = 8
Percentage of oxygen in the M.S.G. =37.85 %
c = 3.99 ≈ 4
Percentage of nitrogen in the M.S.G. = 8.29 %
d = 1
Percentage of sodium in the M.S.G. =13.60 %
e = 0.99 ≈ 1
The molecular formula be :
Answer: The primary consumers are zooplankton, corals, sponges, Atlantic blue tang, and queen conch.

The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses.</span>
