Pls thx! : ) two states of matter are described below. state a: changes shape and volume state b: changes shape but not volume which combination of the state and a substance in that state is correct? state a = juice; state b = block of wood state a = hydrogen; state b = block of wood state a = oxygen; state b = juice state a = air; state b = neon

in general there are rhree states of matter

1. Solid

2. liquid

3.Gas

Solids are characterized by a fixed shape and volume. They do not change their shape and volume with container as the particles in them are closely packed and have strong intermolecular forces of attraction.

In case of liquids they have definite volume however they do acquire the shape of container. the molecules less closely placed than solid as they have weaker intermolecular forces of attraction as compared to solids.

Gas has neither definite shape not definite volume.

They have weakest force of attractions

hence answer is

State A: changes shape and volume, muat be a gas

State B: changes shape but not volume , must be a liquid

State A: oxygen gas

State B: juice

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

i'm assuming that it's c.) red bank..
