The mass of mercury (Hg) in the products formed as a result of the decomposition of 100g of mercury oxide is 93g (option A).
<h3>What is the law of conservation of matter?</h3>
The law of conservation of matter states that the mass of an element can neither be created nor destroyed.
The law further states that in a chemical reaction, the mass of the reactants must equal the mass of products.
According to this question, 100g of mercury oxide decomposes to produce oxygen of oxygen (O) and mercury (Hg) in a chemical reaction.
If 7g of oxygen (O) is produced in the reaction, the mass of mercury as the other product will be 100g - 7g = 93g.
Therefore, the mass of mercury (Hg) in the products formed as a result of the decomposition of 100g of mercury oxide is 93g.

Answer:
The correct answer to the question is Option E (Strongly retained analytes will give broad peaks).
Explanation:
The other options are true because:
A. Initial temp = 50 °C
Final temp = 270 °C
Differences in temp = 270 - 50 = 220°C
Rate = 10 °C/minute.
So, at 10 °C/minute,
total of 220°C /10 °C = number of minutes required to reach the final temp.
220/10 = 22 minutes
B. A column has a minimum and maximum use temperature. Solutes that are already retained would remain stationary while temperatures are low. This would only change if there is an increase in temperature. Heat transfers more energy to the liquid which would make the solute interact with the column phase.
C. Weakly retained solutes may contain larger molecules, will separate by absorbing into the solvent early in separation making the mobile phase separates out into its components on the stationary phase.
D. Retained solute's vapor pressure is higher at higher temperatures making it possible for particle to escape more from the solute when the temperature is high than when it is low.
I believe what you are talking about is the synthesis reaction
Answer:
True
Explanation:
Electrons that are in the first energy level (energy level 1) are closest to the nucleus and will have the lowest energy. Electrons further away from the nucleus will have higher energy. An atom's electron shell can accommodate 2n2 electrons, where n is the energy level.
