A sample of ammonia gas occupies a volume of 2.23 L at 20°C and a pressure of 0.875 atm. What volume will the sample occupy at 1.50 atm and 10°C? (K = °C +273)

the question was hard

Explanation:

I can't answer

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.
