Volume of solution in liters:
5.00 x 10² mL / 1000 => 0.5 L
number of moles:
mass of solute / molar mass
21.1 / 119.0 => 0.1773 moles
Molarity = number of moles / volume
M = 0.1773 / 0.5
M = 0.355 mol/L

Answer:
Ethane (1.09 A) > Ethene(1.076 A) > Ethyne(1.06 A)
Explanation:
The types of bonds present are:
a) Ethane : single bond
b) Ethene : double bond (one sigma one pi)
c) Ethyne: triple bond (one sigma and two pi bonds)
More the number of bonds lesser the bond length.
Thus the order of bond length of carbon-carbon bond will be:
Ethane (1.09 A) > Ethene(1.076 A) > Ethyne(1.06 A)
Answer:
Specifically 100 billion-400 billion.
HCl + NaOH -> NaCl + H2O
reactants: hydrochloric acid HCl
sodium hydroxide NaOh
products: sodium chloride (table salt) NaCl
dihydrogen monoxide (water)
H2O
So, based on the given information, scientists were capable of using models to represent the shape of the structure. The shape resembled a soccer ball.
However, scientists were not able to represent color, size, bonding or chemical structure of the molecules, they only resembled the shape of the submicroscopic matter.
Based on the above, the function this model served in science is:
The model presents a visual picture of submicroscopic matter.
