Answer:
See explaination
Explanation:
Going by the clues that it is between Silver Flouride (AgF) and Sodium Fluoride (NaF) and since it is an aqueous solution , the 1 liter bottle is likely to be Sodium Chloride( NaCl). Going by the reaction,
AgF + NaCl= AgCl + NaF
Here, the color of AgCl is white, hence the solution cannot be AgCl.
Determination of NaCl
Determination of NaCl can be done by Mohr's Method or Volhard's method. But results in Volhard's method are more accurate . Its uses the method of back titration with Potassium Thiocynate which forms a AgCl precipitate . Prior to titration,excess AgNO3 ( The problem also has a clue that excess reagents are present in the lab ) is added to the NaCl solution so that all the Cl- ions react with Ag+. Fe3+ is then added as an indicator and the solution is titrated with KSCN to form a silver thiocyannite precipitate (AgSCN). Once all the silver has reacted, a slight excess of SCN- reacts with Fe3+ to form Fe(SCN)3 dark red complex. The concentration of Cl- is determined by subtracting the titer findings of Ag+ ions that reacted to form AgSCN from the Ag NO3 moles added to the solution. This is used because pH of the solution is acidic. If the pH of solution is basic, Mohr's method is used.
Reactions
Ag+ (aq)+ Cl-(aq) = AgCl(aq)
Ag+(aq) + SCN-(aq) = AgSCN(aq)
Fe3+(aq) + SCN-(aq) = [FeSCN]2- (aq)
Answer:
it would be the second one thank me later
Explanation:
Answer:
Volume = 4.28L
Explanation:
Charles's gas law relates the volume and temperature of a gas at constant pressure. This law says that at constant pressures if we raise the temperature of a gas it will expand and if we reduce the temperature the volume will decrease. The formula is as follows:
So, the initial conditions are 2.22L and 23.9 °C ant the final conditions are 46.1 °C we replace them in the equation. And then we solve it.
Water molecules are made of hydrogen atoms and one oxygen atom.

A polyribosome (or polysome) is a complex of one mRNA molecule and two or more ribosomes that form a polypeptide chain during active translation. Since multiple ribosomes can translate mRNA simultaneously, many polypeptides can be produced simultaneously from a single mRNA.
<h3>Role of all molecular constituents present in a functional polyribosome ;</h3>
1. mRNA: contains the codon
2. tRNA : contains the anticodon for the mRNA
3. Ribosome (large & small subunits): facilitates interaction between mRNA and tRNA
4. Amino acids:
5. Initation Factors: proteins important in the interaction/binding of the small subunit, mRNA, TRNAmet, and the Shine Dalgarno sequence
7. Elongation Factors: bring charged tRNA's to the A site of the ribosome
8. GTP: provides energy
Ribosome recruitment in eukaryotes occurs when the eukaryotic initiation factor e1F4F and poly(A) binding protein (PABP) recognize 5′-capped mRNAs and recruit the 43S ribosome complex to this site. increase. In addition, the Kozak consensus sequence ACCAUGG is also required for translation initiation. Therefore, at first glance, it seems unlikely that overlapping sequences will be translated.
