<h3><u>Answer</u>;</h3>

D. All polysaccharides are made up of carbon, hydrogen, and oxygen.

<h3><u>Explanation</u>;</h3>
  • A polysaccharide is a large molecule made of many monomers called monosaccharides such as glucose, galactose, fructose, etc.
  • Polysaccharides can be homopolysaccharides, where all monosaccharides are the same or heteropolysaccharide in which the monosaccharides vary.
  • They may be linear, where a molecule of polysaccharides has straight chain of monosaccharides, or branched polysaccharides in which a chain has arms.
  • <em><u>All polysaccharides contain oxygen, hydrogen and carbon atoms like all the carbohydrates.</u></em>

Ammonia, NH3, is a weak base that is often used in household cleaning solutions. what is the pH of a solution of ammonia that co
Arte-miy333 [17]

Answer:

11.44

Explanation:

K_b = Base ionization constant of ammonia = 1.8\times 10^{-5}

m = Mass of ammonia = 5 g

V = Volume of ammonia = 709 mL = 709\times 10^{-3}\ \text{L}

M = Molar mass of ammonia = 17.03 g/mol

Molaritiy of ammonia

C=\dfrac{n}{V}\\\Rightarrow C=\dfrac{\dfrac{m}{M}}{V}\\\Rightarrow C=\dfrac{\dfrac{5}{17.03}}{709\times 10^{-3}}\\\Rightarrow C=0.414

We have the relation

pOH=\dfrac{1}{2}(pK_b-\log C)\\\Rightarrow pOH=\dfrac{1}{2}(-\log (1.8\times 10^{-5})-\log 0.414)\\\Rightarrow pOH=2.56

pH+pOH=14\\\Rightarrow pH=14-pOH\\\Rightarrow pH=14-2.56\\\Rightarrow pH=11.44

The pH of the solution is 11.44.
