Helium gas is taking up space inside the floating balloon Air is taking up space inside the other balloon
Someone else cannot sit in the seat you are sitting in
at the same time. You take up the space in the seat.
All matter takes up space, even matter you cannot
see. Gases, such as helium or air, fill up the space
inside balloons like the ones in the photo
10. The gas inside each balloon takes up the same
amount of space. The difference in the mass of
the balloons is only a few grams at most. The
balloon resting on the table is filled with air. The
floating balloon is filled with helium gas. Why
might the helium balloon float while the other
rests on the table?
Helium has less mass in the same amount of space than air does so the helium sinks in the air
Helium has less mass in the same amount of space the air does, so the helium balloon floats in
the air
Air has less mun the same amount of space the hellum does so the helium balloon floats in
5 theme of the humoothe helium balloon sinkin

- decrease the number of plants and animals living in the water.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

personal, she chose to do it.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
