Answer:

The pressure of the balloon is 0.98 atm

Explanation:

Using the equation P1V1 = P2V2, you can solve for the value of V2, which is 0.98 atm.

(P1V1)/P2 = V2

Plug in the numbers:

(6.5*1.5)/10.00

=0.975 atm

=.98 atm

Which of the following elements has the smallest ionic radius?
GaryK [48]

Answer:

Lithium

Explanation:

Lithium is an alkali metal. This means that lithium is expected to be a member of the group one elements on the periodic table.

The group one elements ionize by losing one electron. Hence, the form univalent positive ions after ionization.

Lithium has 3 electrons, 2 belonging to the k shell with the valence L having the other electron. Upon ionization, it forms the ion Li+.

This means it has lost the electron in the valence shell probably through an ionic transfer. This means the only electron it has is in the S shell, which is of a smaller size when compared to elements having multiple rings of shell.

It is expected that negative ions become larger when they ionize as they receive more electrons while that of metals I.e positive electrons shrink when they ionize as they are givers of electrons.

If the pressure of a gas is 100 kPa when the volume is measured to be 500 mL. What pressure would need to be exerted to have the
Korvikt [17]

Answer:

p2=125 kpa

Explanation:

Using Boyle's law

p1 x v1 = p2 x v2

p1=100kpa

v1=500ml

p2=?

v2=400ml

p2= (100x500)\400

p2=125 kpa
