Using the HH eq. calculate the amounts (masses) of sodium phosphate monobasic monohydrate (NaH2PO4 H2O) and sodium phosphate dib

asic anhydrous (Na2HPO4) required to prepare 200 mL of a 100 mM phosphate buffer at pH 6.24. Assume a pK, of 7.2 for the monobasic phosphate. This buffer will be used in the activity assay of our purified lysozyme in a few short weeks. Again scan/photo a copy of your work, or use equation editor/Word to show calculations.

A gas initial volume and pressure is 5m^3 and 101320 Pa and allows to expand up to 12m^3 then what is the final pressure?
Anton [14]

Answer:

New pressure = 42216.66 Pa

Explanation:

Given that,

Initial volume, V₁ = 5 m³

Final pressure, P₁ = 101320 Pa

Final volume, V₂ = 12 m³

We need to find the final pressure of the gas. We know that the relation between pressure and volume is given by :

P\propto \dfrac{1}{V}\\\\P_1V_1=P_2V_2\\\\P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{101320 \times 5}{12}\\\\P_2=42216.67\ Pa

So, the new pressure is equal to 42216.66 Pa.

Which of the following options is correct?
Elena-2011 [213]

Answer:

b. cellulose.

Explanation:

Cellulose is a polysaccharide consisting of a long chain of repeating glucose units (i.e., β-D-glucose units) that produce long unbranched chains. Cellulose can be considered as a natural polymer (i.e., a non-modified carbohydrate) because it is composed of repeated chains of β-D-glucose molecules stuck together. The cellulose polysaccharide is a principal component of plant cell walls.

Gloria is writing the chemical formula for a compound using its chemical name. She has just identified the names of the elements
disa [49]
She will use the periodic table of elements to not only find out the chemical symbols of the elements written within the name, but also to check whether or not the elements are metals and or nonmetals, from this determine the ionic charges if needed for metals, and for metals that have more than one ionic charge, use a Roman numeral to represent the ionic charge that she would be using in writing the chemical formula of the compound.
