Hello!
To solve this problem, we will use the Boyle's Law, which describes how pressure changes when volume changes and vice-versa. The equation for this law is the following one, and we'll clear for V2:
So, the final volume after increasing the pressure would be 2,7 L. That means that volume decreases when the pressure increases
Have a nice day!

Answer:
This question is incomplete without the table
Explanation:
The missing table is attached to this answer.
There are three subatomic particles found in an atom; protons, neutrons and electrons. The properties of the subatomic particles will be classified under the following subheadings (which are the empty columns/boxes in the attachment)
SYMBOL
The symbol of proton is "p⁺", the symbol of neutron is "n⁰" and the symbol of electron is "e⁻".
CHARGE
Looking at the symbol of the subatomic particles, one can guess the charge of each of the particles from the superscript.
Protons are positively charged, electrons are negatively charged while neutrons have no charge/electrically neutral.
The relative charge of proton is +1 while it's absolute charge is +1.60218 × 10⁻¹⁹
The charge of a proton was first determined by Ernest Rutherford using the gold-foil experiment
The relative charge of electron is -1 while it's absolute charge is -1.60218 × 10⁻¹⁹
The charge of an electron was first determined by R. Milikan using the oil-drop experiment
The relative charge and absolute charge of neutron is 0
The charge of a neutron was first determined by (or credited to) James Chadwick.
MASS
The relative mass (amu) of proton is 1.00727 while that of neutron is 1.00866. The relative mass (amu) of an electron is 0.00054858 while it's absolute mass (g) is 9.10939 × 10⁻²⁴.
The mass of an electron was first measured by J. J. Thomson.
The mass of a proton was first measured by (or credited to) Ernest Rutherford.
The mass of a neutron was first measured by James Chadwick.
LOCATION
The protons and neutrons <u>are located inside the nucleus</u> which is found in the centre of an atom while the electron(s)<u> is/are found outside the nucleus but within the atom</u>.

Explanation:
Carbon is a non-metal and has 6 electrons. In the excited state, it contains 4 electrons in its outermost shell and so 4 electrons take place in covalent bond formation. In a molecule , 2 carbon atoms can be bound by a single bond, the double bond and by a triple bond. Since the bond length of is 120 pm, the bond length of
is 134 pm and the bond length of
is 154 pm. Thus in the given compound,
, in which
is labeled as 1,
is labeled as 2 and
is labeled as 3. So the bond length of carbon-carbon bonds in the molecule, in decreasing order is
.
