If 840. mL of linseed oil has a mass of 700. g, calculate the density of linseed oil.
aleksklad [387]

Density can be determined as:

d = m /V

whereas, m is mass of compound

v is volume

d = 700 /840 = 0.83 g /mL

Thus density is 0.83 g /mL

In nature, one common strategy to make thermodynamically unfavorable reactions proceed is to couple them chemically to reactions
padilas [110]

Answer:

\triangle G= -6.7 KJ/mol

Explanation:

From the question we are told that:

Chemical Reactions:

X=A⇌B,ΔG= 14.8 kJ/mol

Y=B⇌C,ΔG= -29.7 kJ/mol

Z=C⇌D,ΔG= 8.10 kJ/mol

Since

Hess Law

The law states that the total enthalpy change during the complete course of a chemical reaction is independent of the number of steps taken.

Therefore

Generally the equation for the Reaction is mathematically given by

T = +1 * X +1 * Y +1 *Z

Therefore the free energy, ΔG is

\triangle G=1 * \triangle G*X +1 * \triangle G*Y +1 * \triangle G *Z

\triangle G= +1 * (14.9) +1 * (-29.7) +1 * (8.10)

\triangle G= -6.7 KJ/mol

At least three types of RNA are required for protein synthesis. Compare and contrast mRNA, rRNA, and tRNA by moving the descript
Vedmedyk [2.9K]

Explanation:

The difference among mRNA, tRNA and rRNA are:

mRNA: It carries DNA's protein building information from nucleus to the cytoplasm. It is also read as codons nucleotide triplet that indicate specific amino acids .

rRNA: The function of rRNA is to join amino acids to the peptide bonds.

tRNA:  Delivers amino acids to the site of protein synthesis. It also has an anticodon that interact with specific codon of another nucleus.

The similarity among mRNA, rRNA and tRNA is that they all consists of ribonucleic  acid and can exist outside the nucleus in eukaryotes.
