Amixture of gases at a total pressure of 95 kpa contains nitrogen, carbon dioxide and oxygen. the partial pressure of carbon dioxde is 24 kpa and the partial pressure of the nitrogen is 48 kpa. what is the partial pressure of the oxygen?
a) 33kpa
b) 23 kpa
c) -3 kpa
d) 0.003 kpa

23 kPA

Explanation:

95kPa = 24kPA (CO2) + 48 kPa (N) + x kPa (O)

24kPA(CO2)+ 48kPA (N) = 72 kPA

95kPA - 72kPA= 23kPA (O)

they are made of gases.

they have a spherical shape.

they make energy through fusion.

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.
