DNA and RNA can also be ISOLATED from the same biological sample.
So the answer is no, both DNA and RNA are together.
Answer:
The correct approach is "-2.67 kJ/mole". A further solution is described below.
Explanation:
The given values are:
No. of moles,
= 5.60 mol
Substance releases,
ΔH = 14.9 kJ
Now,
The ΔH in terms of kJ/mol will be:
= 
On putting the given values of ΔH, we get
= 
= 
Answer:
6.3moles
Explanation:
The balanced chemical equation for the decomposition of phosphorus oxychloride (POCl3) is as follows:
POCl3 → POCl + Cl2
Based on the above decomposition reaction, it shows that;
1 mol of POCl3 will decompose to give 1 mole of Cl2
Hence, 6.3 moles of POCI3 will give 6.3 moles of Cl2.
Explanation:
They are indeed placed from the far left hand side of the periodic table in almost the same column. If you step around the table between left to right, the movement of electrons rises by one. When you progress down the line, the number of power increases by the one.
