The answer is B.) The dissolving of a sugar cube in a cup of coffee.
Answer:
A. Glucose
Explanation:
Glucose is a monomer and not a polymer. So, option (A) is not a polymer.
Answer:
89.94 %
Explanation:
Considering:
Or,
Given :
For HCl :
Molarity = 0.500 M
Volume = 22.5 mL
The conversion of mL to L is shown below:
1 mL = 10⁻³ L
Thus, volume = 22.5×10⁻³ L
Thus, moles of HCl :
Moles of HCl = 0.01125 moles
The reaction of NaOH and HCl is:
NaOH + HCl ⇒ NaCl + H₂O
Moles of HCl = Moles of NaOH
<u>Thus, Moles of NaOH = 0.01125 moles</u>
Molar mass of NaOH = 39.997 g/mol
The formula for the calculation of moles is shown below:
Thus,
Total mass = 0.500 g
<u>% purity = ( 0.4497 / 0.500 ) × 100 = 89.94 %</u>
The outcome of a experiment is the result
Answer:
ions need to be present in the water. If there are no ions in solution, no electricity is conducted. since, in water, electricity is conducted, this means that HCl completely ionizes to H + and C l − ions. However, in chloroform, since there is no conduction, HCl does not ionize and stays as the
