Answer:
The correct answer is option (1).
Explanation:
Mass of the sample = 5.5 g
Percentage of carbon in sample = 35 %
Percentage of oxygen in sample = 100% - 35%
Mass of carbon in a sample: (35%) of 5.5 g
Mass of oxygen in a sample: (100%-35%) of 5.5 g
Answer:
Lipid forms structures in cells and stores energy
Explanation:
A is the correct answer from what i understand in this question
Total weight of alloy is
67 + 20 = 87 g
67 g of which is gold
So % gold is 67/87* 100 = 77.01%
The concentrations of reactants and the products are not constant and the rates of the forward and reverse reactions are equal. and these reactions are not at equilibrium.
<u>Explanation:</u>
The conditions to attain equilibrium is that,
- Conversion of reactant to product and vice versa occurs at the same rate.
- The system is a closed system.
- The temperature remains constant.
- Concentration of every substance remains constant.
- Rate of forward and reverse reactions will be different.
So the answer is The concentrations of reactants and the products are not constant and the rates of the forward and reverse reactions are equal.
