The new volume when pressure increases to 2,030 kPa is 0.8L
BOYLE'S LAW:
The new volume of a gas can be calculated using Boyle's law equation:
P1V1 = P2V2
Where;
- P1 = initial pressure (kPa)
- P2 = final pressure (kPa)
- V1 = initial volume (L)
- V2 = final volume (L)
According to this question, a 4.0 L balloon has a pressure of 406 kPa. When the pressure increases to 2,030 kPa, the volume is calculated as:
406 × 4 = 2030 × V2
1624 = 2030V2
V2 = 1624 ÷ 2030
V2 = 0.8L
Therefore, the new volume when pressure increases to 2,030 kPa is 0.8L.

Answer:
Planetary orbits are all nearly circular , comet orbits are highly excentric . ... This means that planets stay more or less at the same distance from the sun, while comets travel as far out as beyond Neptune, and can travel as far in as Mercury.
Answer: Batteries and Food
Explanation:
On the batteries that we use for example for a watch in the kitchen, occurs a chemistry reaction, called redox between Zn and MnO2. The Zn is oxidized (in the anode) and the MnO2 is reduced (in the cathode). In the oxidation, the athom loses electrons and in the reduction the opposites.
Regarding the chemical reactions that occur in the food that we consume, the hydrolisis that occurs in the stomach. The hydrochloric acid that is secreted in the stomach allows the activation of an enzyme, pepsinogen, which hydrolyzes the proteins present in the food consumed. That is, it hydrolyzes the peptide bonds of the proteins, which is between an amino and carboxyl bond of each amino acid that makes them up.
Reaction of Copper with Mercuric Nitrate is as follow,
Cu + Hg(NO₃)₂ → Cu(NO₃)₂ + Hg
According to equation,
1 Mole of Cu reacts to form = 1 Mole of Hg
So,
1.20 Moles of Cu will react to produce = X Moles of Hg
Solving for X,
X = (1.20 mol × 1 mol) ÷ 1 mol
X = 1.20 mol of Hg
Result:
1.20 mole of Cu when reacted with mercuric nitrate produces 1.20 moles of Hg.
