A balloon (approximate as a sphere) is inflated such that its radius is 7.00 cm. What is the volume of air inside the balloon
in mL? (Volume of a sphere Tor3 use 3.14 for TT)
=
mL

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

the answer is na (sodium)

catya your not at all which answer i've seen you do this on another question!

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
