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
An alp-ha particle is equivalent to the nucleus of a helium atom. Helium Atom = Answer.
Answer:
c it does not change the energy state
Explanation:
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.
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
