A laboratory bottle of helium gas occupies a volume of 2.0 L at 760 mm Hg. Calculate the new pressure if the volume falls to 1.8 L.

Idid the calculation and i get 875,000,000 which can be written as 8.75 x 10^6?

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom

Ithink is a because if say increased in electronegativity
