A sample of hydrogen gas (3.2 l) at 3.5 atm and 25 °c was combined with 5.2 l of nitrogen gas at 7.3 atm and 25 °C at constant temperature in a 15.0 l flask. Assuming the initial pressure in the flask was 0.00 atm and the temperature upon mixing was 25 °., What is the total pressure (atm) in the flask?

chemical properties are the characteristic of matter which can only be observed by changing the chemical identity of a sample like flammability reactivity and toxicity.

explanation:

yes the other ones are right just show me a pic of ur face cuz u look hot

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.
