Answer:
Explanation:
The equation of the reaction of Silver sulfide with aluminum in the presence of sodium bicarbonate (NaHCO₃)
3 Ag₂S(aq) + 2 Al(s) → 6 Ag (s) + Al₂S₃(aq)
The word that best fits the underlined in the sentence is "free-to-rotate." The carbon atoms in their carbon bonds are free to rotate since alkanes do not have geometric isomers. They only have single bonds and the most common example of which are trans molecules.
The overall reaction order is 2, because you add the orders of the individual components, which each are 1.
hydrogen is the lightest element in the periodic table
Explanation:
DNA is composed of large amount of amino acids and have a lot of amide groups .
Therefore , in the acidic or in basic medium , the DNA molecules is either dissociated or dis stabilized via protonation or de protonation .
<u>The double helix structure of the DNA may break or get dis ordered .</u>
But , from the question , In sodium phosphate buffer at pH = 7.0 , is the neutral condition , hence , the DNA remains unchanged , because of the neutral medium .
And in pure water ,
The DNA molecule remains intact as , in pure water , there are no ions .
