if we seal up a 2 liter bottle that was at a standard pressure of 760mmHg and room temperature is 26°C what will be the temperature of the air inside the bottle if we use a bike pump to increase the pressure to 800mmHg? Give the numeric answer in kelvin.

Although respiratory organs vary across different organisms, they all contain respiratory surfaces that have a large surface area and are extremely thin. explain why having an extremely thin respiratory surface with a large surface area is advantageous for the process of gas exchange

The chemical bond connecting one nucleotide with the next one along the nucleic acid chain is called a

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
