Bogdan [553]

Answer:

The answer to your question is the letter C) 5648 kJ/mol

Explanation:

Data

                C₁₂H₂₂O₁₁  +  12 O₂  ⇒   12 CO₂  +  11 H₂O

H° C₁₂H₂₂O₁₁ = -2221.8 kJ/mol

H° O₂ = 0 kJ / mol

H° CO₂ = -393.5 kJ/mol

H° H₂O = -285.8 kJ/mol

Formula

ΔH° = ∑H° products - ∑H° reactants

Substitution

ΔH° = 12(-393.5) + 11(-285.8) - (-2221.8) - (0)

ΔH° = -4722 - 3143.8 + 2221.8

Result

ΔH° = -5644 kJ/mol

RUDIKE [14]

The question is in incomplete, so here is the complete question:

Nucleic acids are polymers of just 4 different monomers in a linear arrangement. How many different nucleic acid polymer sequences are possible when the polymer contains 30 monomers?

Polymers are biomolecules formed by monomers. For nucleic acid, like DNA and RNA, as 4 monomers are necessary to "create" 1 polymer, a polymer containing 30 monomers can "produce" 7 different nucleic acid sequences.

Determine the number of moles of Cr atoms in 50.00grams of Cr2Cl3
Darina [25.2K]
We know from the formula of Cr₂Cl₃, that each mole of the compound consists of 2 moles of Cr. Thus,
moles of Cr = moles of Cr₂Cl₃ x 2
= 0.3155 x 2

= 0.631 mole of Cr
