Liquids take the shape of the bottom of their container, while gases take the shape of their entire container. The shape solids take, however, is independent of their container. In 3-5 sentences, explain these patterns. (4 points)

liquid doesn't have any type of Shape it have only volumes that's why why the container in which it kept liquid takes shape of that container and because of higher density

and in in gases we see that it takes the the container shape because of it have a very less density the molecules of gases very far to each other so that's why gases takes shape of the container

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
