The pressure on a 200-milliliter sample of co2(g) at
constant temperature is increased from 60 kpa to
120 kpa. what is the new volume of the gas? a) 100 ml b) 300 ml
c) 400 ml d) 600 ml

A) 100 mL

Explanation:

At constant temperature and number of moles, Using Boyle's law  

Given ,  

V₁ = 200 mL

V₂ = ?

P₁ = 60 kPa

P₂ = 120 kPa

Using above equation as:

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.

since electrons are negative the answer is neagtaive
