daser333 [38]

Answer:

4.2moles

Explanation:

"The answer to your question is 4.2 moles of H₂O

Explanation:

Data

moles of H₂O = ?

moles of C₂H₆ = 1.4

Balanced chemical reaction

2C₂H₆ + 7O₂ ⇒ 4CO₂ + 6H₂O

Process

To determine the moles of H₂O, use proportions and the coefficients of the balanced chemical reaction.

2 moles of C₂H₆ 6 moles of H₂O

1.4 moles of C₂H₆ x

x = (1.4 x 6) / 2

x = 8.4/2

x = 4.2 moles of H₂O"

Ugo [173]

Answer:

(B) The organism lives and replicates despite protease and DNase treatment, but the organism dies when treated with RNase.

Explanation:

DNA is the genetic material in present day organisms while some of the proteins serve as enzymes and catalyze the metabolic reactions.

An organism having RNA with the ability to serve as genetic material would not require DNA to survive. Likewise, if RNA molecules in these organisms also serve as the enzyme, proteins would not be required for survival.

Therefore, when treated with DNase and protease that digest the DNA and proteins respectively, these organisms would be able to survive. However, treatment with RNase enzymes that digest the RNA would kill them as RNA was their biocatalyst and genetic material.
