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 .
Answer:
82.6 moles
Explanation:
chemical equation:
CO2+ 4H2 → CH4 + 2H2O
Given data:
moles of carbon dioxide = 82.6 mol
moles of methane = ?
through the balanced chemical equation we will compare the moles carbon dioxide with methane
CO2 : CH4
1 : 1
82.6 : 82.6
we are given hydrogen so 82.6 moles of carbon dioxide will produce 82.6 moles of methane.
Answer:
1Ag+2S⇔1Ag2S
Explanation:
The first step is to see how many of each element are on each side of the equation. There is one silver on the left and one silver on the right, so you can leave those alone. However, there is one sulfur on the left and two on the right. You cannot multiply the right by 2 because then that would upset the balance of the silver, but you can multiply the sulfur by 2. Therefore, the equation should be 1Ag+2S⇔1Ag2S. Hope this helps!

Answer:
There are 3 significant figures in 675000
Explanation:
The rules for significant figures:
- Non zero digit (from 1 upward) are always significant
- Trailing zero are not significant
- but zero in the presence of decimal are significant
In this case, the trailing zeros are not significant thus only the first 3 non zero digit are significant.
