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.
Answer: Your mass would be the same, but you would weigh less because the gravity on the moon is less than it is on Earth.

Answer:
D. Anti-periplanar
Explanation:
In the <u>second step</u> of the intramolecular William Ether Synthesis mechanism (figure 1) we will have the attack of the negative charge of the oxygen to the carbon bond to the Br. At the same time the Br leaves, so a bond would be broken (the <u>C-Br</u> bond) and a bond would be formed (the <u>C-O</u> bond).
Now, this process can happen only if the <u>attack</u> and the <u>leaving group </u>has an anti configuration (figure 2). In an anti configuration the <u>nucleophile</u> and the <u>leaving group</u> would have <u>opposite directions</u>.
Answer:
22g
Explanation:
Given parameters:
Mass of element A = 18g
Mass of element B = 4g
Unknown:
Mass of compound formed = ?
Solution:
The reaction equation is given as;
A + B → AB
According to the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".
Simply mas is conserved and the mass of the reactants is the same as the mass of the product that forms.
Mass of reactants = mass of A + mass of B = 18g + 4g = 22g
So;
Mass of product AB = 22g
