Answer:The new volume is 5mL
Explanation:
The formular for Boyles Law is; P1 V1 = P2 V2
Where P1 = 1st Pressure V1 = First Volume
P2 = 2nd Pressure V2 = Second Volume
From the question; P1 = 5atm, V1 = 10ml
P2 = 2 x P1 (2 x 5) = 10 atm V2 =?
Using the Boyles Law Formular; P1 V1 = P2 V2, we make V2 the subject of formular; P1 V1/ P2 = V2
∴ 5 x 10/ 10 = 5
∴ V2 = 5mL
Answer:

Explanation:
We are given the (R)-3-bromo-2,3-dimethylpentane and asking to draw the curved arrow which is the showing the mechanism for first-order substitution and first-order elimination reactions. We know the formation of carbocation is the rate determining step in the first-order substitution and first-order elimination reactions.
So in the (R)-3-bromo-2,3-dimethylpentane there is –Br gets removed and formed the tertiary carbocation which is more stable, so the curved arrows in Box 1 to depict the flow of electrons and intermediate in Box 2.

The answer would be: K
Kalium or Potassium is one of the metal that located in the first column of the periodic table. It was a strong base with one valence. If react with water it would have an equation:
2K + 2H2O = 2KOH + H2
The kalium hydroxide will form ion if put on the aqueous state. It will become K+ and OH-, thus increasing the water pH.
We use the following formula for calculating the density:
p = m/v
Where:
m = mass
v = volume
So, we have:
p = 46 /5
p = 9,2 g/cm³
