The IUPAC name of the compound <span>ch3–ch2–c ≡ c–ch3 is
PEN-2-YNE or
2-PENTYNE.
Attached below is a diagram that fully explains how the name was given and derived.</span>
Solids have a definite shape and volume. They are always the same shape no matter what they are contained in; their volume is also the same because they don't change unless you add or take away from it.
____________________________________________________________
Liquids have an indefinite shape but definite volume. They expand to fill out the space they are contained in, but their volume doesn't change unless you take out or add more of the liquid.
Gases have an indefinite shape and volume. Gases expand to fill out the space they are in and also don't have a clear shape because they are not always in one form.
<span>Many scientific investigations have provided evidence to support this as the best explanation of the data</span>
The answer is (1) CaCl2. The reaction formula of this is HCl + Ca(OH)2 = CaCl2 + H2O. This is a reaction of base and acid. So the production is CaCl2 and H2O.
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
