Asample of hydrogen gas has an initial pressure of 2.86 atm and an initial volume of 8472 ml if the volume of the
were decreased to 365.8 ml, what would the new pressure be? gas law used:

Gas law : Boyle's law

New pressure: 66.24 atm

Concept tested: Gas laws (Boyle's law)

We are given,

We need to determine the new pressure, P₂

P₂ = P₁V₁ ÷ V₂

   = (2.86 atm × 8472 mL) ÷ 365.8 mL

   = 66.24 atm

Therefore, the new pressure is 66.24 atm

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
