Hi,
You didn't mention what "the following" were - please add additional information so the problem can be solved.
Answer:
yes, the law of conservation of mass hold true in this case burning magnesium strip is explained by this equation 2 Mg (s) + O2 (g) -> MgO (s)So the lighter magnesium, after reacting with oxygen in air, forms the heavier magnesium oxide. molar mass of magnesium and magnesium oxide are 24g and 40g respectively. So the same ratio 24:40 (i.e. 3:5) is maintained in the given masses of 48g and 80g, which means mass is conserved in the reacion.

Answer:
The answer is: CH₄ < CH₃OH < CH₃CH₂OH < HOCH₂CH₂OH
Explanation:
Boiling point refers to the temperature at which the pressure exerted by the surrounding on the liquid is equal to the vapor pressure of the liquid. The boiling point increases as the molar mass of the substance increases.
Since the molar mass increases in the order:
CH₄ < CH₃OH < CH₃CH₂OH < HOCH₂CH₂OH
Therefore, the order of increasing boiling point:
CH₄ < CH₃OH < CH₃CH₂OH < HOCH₂CH₂OH
Answer:
Neon is the least likely to undergo chemical reaction.
Explanation:
The other elements given in the option do not have 8 electrons in their outermost shell, so they will be quite willing to undergo chemical reactions in order to become stable.
