Answer:
2 K + 1 CrBr2 yield 2 KBr + 1 Cr
Explanation:
Answer:
RNA
Explanation:
The nucleic isolated was quantified by 2 types of fluorescent dyes, which binds only to specific type of nucleic acid. You can find the information on the specificity of dyes on your labsheet or dye supplier's website. For our dyes, however:
- SyBr Green II only emits fluorescent light when it binds to RNA or Single Strand DNA
- PicoGreen only fluoresce when bound to Double Strand DNA
With these information, we know that our nucleic acid is either single strand DNA or RNA, however, it is also mentioned that
"Nucleic acid was isolated by lysing cells in detergent, guanidine isothiocyanate, and DNAse"
DNAse, which is an enzyme that breaks down DNA, destroys any extracted DNA during the process, thus, the only possible nucleic acid we have isolated is RNA
The reaction is:
C₂H₄ + 3O₂ → 2CO₂ + 2H₂O; ΔH = 1410 kJ
When we reverse this reaction, the sign of the enthalpy change, ΔH, will be changed. The enthalpy change for the reversed reaction would be 1,410 kJ.
Next, we must also multiply the reaction by 2, so the final enthalpy change for the reverse reaction will be:
ΔH = 2,820 kJ
Two moles of potassium react with 2 moles of water to form two moles of potassium hydroxide and 1 mole of hydrogen gas. The number of moles of hydrogen gas produced is half the number of moles of water and potassium that react together.
The molar mass of...
