Answer:
True
Explanation:
Natural gas. Natural is its name. (I think)
Mass of HNO3 = ?
V = 0.5L
M.mass of HNO3 = 63.0067u
Molarity = 0.601
molarity = no of moles of solute/volume of solution in L
0.601 = no of moles of solute/0.5
no of moles of solute = 0.3005
mass of HNO3 = no of moles * M.mass
= 0.3005*63.0067
= 18.933g
Density=mass/volume
0.7198=m/11.84
mass=0.06g
You can classify a metal: when a subject can surely conduct electricity.
examples: if a problem says the unknown object is malleable, or says "on the left side of the periodic table", is a conductor, is shiny, etc.
Metalloids: when a subject is alongside the staircase, uses word "semi-conductor", it depends on if it's malleable or ductile, and depends on whether it's shiny or not, etc.
Nonmetal: is located on the right side of the periodic table, can ONLY be an insulator, is not malleable, is not shiny, etc.
