Agas with constant temperature has a pressure of 123 kpa and a volume of 123.13 l. a pressure change caused the volume to decrease to 28.15 l. what is the new pressure?

T = const.

P1 = 123 kPa

V1 = 123.13 L

V2 = 28.15 L

P2 = ?

This is an example of Boyle’s law which describes how the pressure of a gas tends to increase as the volume of the container decreases, meaning that P*V=const. For comparing the same substance under two different sets of conditions, the law can be expressed as P1*V1=P2*V2

P2=P1V1/V2

P2=123kPa*123.13L/28.15 L

P2=538.01 kPa

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
