law and Charles's law.
Gay-Lussac's Law Charles's Law
O involves changes in temperature
O has a constant volume
O shows an inversely proportional relationship
O does not involve pressure changes
Answer:
A) involves changes in temperature
Explanation:
The figure is missing, but I assume that the region marked X represents the region in common between Gay-Lussac's law and Charle's Law.
Gay-Lussac's law states that:
"For an ideal gas kept at constant volume, the pressure of the gas is directly proportional to its absolute temperature"
Mathematically, it can be written as
where p is the pressure of the gas and T its absolute temperature.
Charle's Law states that:
"For an ideal gas kept at constant pressure, the volume of the gas is directly proportional to its absolute temperature"
Mathematically, it can be written as
where V is the volume of the gas and T its absolute temperature.
By looking at the two descriptions of the law, we see immediately that the property that they have in common is
A) involves changes in temperature
Since the temperature is NOT kept constant in the two laws.
The reason why the mass has increased is because The magnesium reacted with the oxygen around is and combined together to make the compound MgO.
Antoine Lavoisier discovered in 1789 that mass is neither created nor destroyed in chemical reactions, which led to the formulation of the Law of Conservation of Mass.
That is to say, the mass of any one element at the start of a reaction will be equal to that element's mass at the conclusion of the reaction. The overall mass will remain constant over time in any closed system if we take into account all reactants and products in a chemical reaction.
Because naturally occurring elements are extremely stable under the circumstances present on the Earth's surface, the Law of Conservation of Mass is valid.
Therefore, The reason why the mass has increased is because The magnesium reacted with the oxygen around is and combined together to make the compound MgO.

Answer: 13.5g
Explanation:
Moles = mass/molar mass
Molar mass of water= 18gmol-1
0.75=m/18
m= 17*0.75= 13.5g
Answer:
The agency's recommended ratio of fluoride to water, newly calibrated at 0.7 parts per million, results from years of scientifically rigorous analysis of the amount of fluoride people receive from all sources.
