Sergio039 [100]

"Polysaccharide carbohydrate" comprises an S. pneumoniae capsule.

<u>Option:</u> C

<u>Explanation:</u>

The lengthy sequences of carbohydrate molecules, primarily polymeric carbohydrates constructed of units of monosaccharides linked together through glycosidic connections, understood as Polysaccharides. This carbohydrate can respond to water by catalyzing amylase enzymes, which generate component sugars.

A major human pathogen is Streptococcus pneumoniae or pneumococcus. The virulence is primarily due to its polysaccharide envelope, which protects it from the recipient immune response, and this has led to comprehensive study of the shell.

exis [7]

Answer:

Na⁺ (aq) + OH⁺ (aq) + H⁺ (aq) + Cl⁻ (aq) → Na⁺ (aq) + Cl⁻ (aq) + H₂O (l)

General Formulas and Concepts:

<u>Atomic Structure</u>

  • Compounds

<u>Aqueous Solutions</u>

  • Solubility Rules
  • States of matter

<u>Stoichiometry</u>

  • Reaction RxN Prediction
  • Balancing Reactions RxN

Explanation:

<u>Step 1: Define</u>

NaOH reacting w/ HCl

NaOH is soluble

HCl is soluble

[RxN] NaOH (aq) + HCl (aq) → NaCl (aq) + H₂O (l)

<u>Step 2: Total Ionic Equation</u>

<em>Break up soluble compounds into ionic form.</em>

[T.I.E] Na⁺ (aq) + OH⁺ (aq) + H⁺ (aq) + Cl⁻ (aq) → Na⁺ (aq) + Cl⁻ (aq) + H₂O (l)
