Hydroxyapatite is the major mineral constituent of bone. The unit empirical formula for hydroxyapatite is Ca5(PO4)3(OH). List the elements found within hydroxyapatite in alphabetical order, written in lower case letters, and separated by commas and spaces (ex. element name, element name, element name...).
Determine the mechanism for the synthesis of p-nitroacetanilide from acetanilide and HNO 3 , nitric acid and H 2 SO 4 sulfuric acid?
If the partial pressure of oxygen in the atmosphere is 0.20 atm, what is the soluability of dissolved oxygen in blood? Recall that soluability constant of oxygen
The pKa of acetic acid, HC2H3O2, is 4.76. A buffer solution was made using an unspecified amount of acetic acid and 0.30 mol of NaC2H3O2 in enough water to make 1.50 L of solution. Its pH was measured as 4.50 on a meter.
The complete conversion of 2-phenylacetic acid to ethyl-2-phenylacetate in this experiment is the result of a. Ethanol being in excess relative to 2-phenylacetic acid
The specific heat of water is 4.184 J/gxC. Assume the density of th water is 1.00g/mL and there is no heat lost or gained by the calorimeter.
There are two reason why the enols of beta-dicarbonyl compounds, such as pentane-2,4-dione are relatively stable. One is that they are conjugated and the pi-electron overlap due to the conjugation provides additional stability.
Question- On the topic of hydrogenation: Why are we using hydrogenated oils and fats in our food? What makes the use of hydrogenated fat problematic
You conbine 16.0g of KO2 with the CO2 in 4.00L tank, in which the gas pressure is 1.24 atm at 23.0C. What is the pressure of the oxygen formed if captured in 2.50L flask at 25.0C
What is the osmotic pressure exerted by sea water on a semi-permeable membrane that separates the sea water from pure water
