DNA and RNA are amplified in vitro using polymerase chain reaction (PCR), which is frequently employed in biochemical analysis.
The PCR process is very temperature sensitive, and thermal management is crucial to PCR operation in order to maintain the necessary set points for temperature at each stage of the procedure. The objective of this investigation is to develop a thermal approach that can quickly boost the heating/cooling thermal cycle speed while keeping the substrate that contains the aqueous nucleic acid sample at a constant temperature. This study examines a novel microfluidic PCR heat cycler that makes use of a suitably configured design that is filled with a porous material.

Answer:
Definitely not. This is because the alkaline earth metal [basically group 2 elements] are reactive and will react with the contents of the can, contaminating it.
4Al + 3O2 -------> 2Al2O3
1)100 g Al into moles
M(Al) = 27.0 g/mol
100g Al* 1 mol Al/27 g Al = 100/27 g/mol Al
2) 4Al + 3O2 -------> 2Al2O3
from reaction 4 mol 2 mol
given 100/27 mol x mol
x= (100/27)*2/4=50/27 mol Al2O3
3) 50/27 mol Al2O3 into g
M(Al2O3) = 2*27.0 + 3*16.0= 102 g/mol
(50/27) mol Al2O3 * 102 g Al2O3/1 mol Al2O3 = (50*102)/27≈ 189 g Al2O3
Answer: 189 g/mol Al2O3.
Balancing of the chemical reaction involves keeping the number of atoms of a certain element equal in both sides of the equation. For this item, the balanced chemical equation would be,
N2 + 3H2 --> 2NH3
The numerical coefficients are therefore 1 for N2, 3 for H2, and 2 for NH3. The sum of the numerical coefficients is 6.
<em>Answer: 6</em>
The first law of thermodynamics states the conversation of energy and heat where the energy in an isolated system may be transformed into another, but never created or destroyed. If 314J of energy was released to the room, then also 314J of energy was removed from food in that refrigerator assuming it is an isolated system
