The reaction between hydrogen and oxygen to form water is given as:
The balanced reaction is:
According to the balanced reaction,
4 g of hydrogen (
) reacts with 32 g of oxygen (
).
So, oxygen reacted with 29.4 g of hydrogen is:
Hence, the mass of oxygen that is reacted with 29.4 g of hydrogen is 235.2 g.
Answer: Number of moles of NaCl per liter of solution
Explanation: Molarity can be defined as the number of moles
of solute per liter of solution.
Therefore the molarity of an aqueous solution of NaCl is thus defined as the number of moles of NaCl per liter of solution.
The mass defect in amu/atom is 11.928.
The mass defect is the discrepancy between the nucleus of an atom's anticipated mass and its actual mass. This discrepancy is due to the binding energy of a system, which might manifest as excess mass.
The nucleus must be robustly spherical as expected for a doubly magical nucleus because the stripped neutron fell into a distinct orbital shell above the closed inner shells of tin-132 after the researchers examined the energy and angular distribution of the particles.
Mass of atom = 131.917760 amu
Mass of proton = 1.007825 amu
Mass of neutron = 1.008665 amu
Sn atom has 50 protons and 69 neutrons.
Mass defect = Mp + Mn - MA
= 50 × 1.007825 + 69 × 1.008665 - 131.917760
= 50.39125 + 69.597885 - 131.917760
= 11.928 amu/atom
Therefore, the mass defect in amu/atom is 11.928.

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.
