Answer:
Third figure shows the best relationship.
(c) is correct option.
Explanation:
Given that,
The diagram best represents the relationship masses of subatomic particles.
We know that,
The mass of proton and neutron are same.
The mass of electron is less than mass of the proton and neutron.
We need to find the best represents the relationship masses of subatomic particles
According to figure,
Third figure shows the best represents the relationship masses of subatomic particles.
Hence, Third figure shows the best relationship.
(c) is correct option.
Answer:
Explanation:
The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood. Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells.
Answer:
54.5%
Explanation:
The percentage composition of oxygen in C₆H₈O₆ can be obtained as follow:
Molar mass of C₆H₈O₆ = (12×6) + (8×1) + (16×6)
= 72 + 8 + 96
= 176 g/mol
Next, there are 6 oxygen atoms in C₆H₈O₆. Therefore the mass of oxygen in C₆H₈O₆ is:
Mass of Oxygen = 16 × 6 = 96 g
Finally, we shall determine the percentage composition of oxygen in C₆H₈O₆ as follow:
Percentage of oxygen =
Mass of Oxygen/mass of C₆H₈O₆ × 100
Percentage of oxygen = 96 / 176 × 100
Percentage of oxygen = 54.5%
Thus, the percentage composition of oxygen in C₆H₈O₆ is 54.5%.
