What are some of the natural sources of amino acids?
How does amino acid supplements effectively provide the amino acids our body needs? Are they as effective as the natural sources that God gave us?
Atom hybridization changes in many chemical reactions. In each of the following reactions, determine what change, if any, occurs to the hybridization of the underlined atom. (a) SO3 + H2O → H2SO4
Nonfat dried milk is produced by spray-drying skim milk. During dehydration, the water activity (Aw) was monitored as mositure was removed. The graph shown below contains isotherms for dehydration of teh skimmilk
Calculate the molarity of a 97.12 wt% acetic acid solution given that the solution density is 1.05 g/mL
What practical advantage does an extraction solvent that is denser than water have over one that is less dense
Problem- Galium has two naturally occurring isotopes: 71Ga with a mass of 70.9171 amu and a natural abundance of 39.89% and 69Ga. What is the mass of 69Ga in units of amu
2Al(s)+2KOH(aq)+6H2)-->2KAl(OH)4(aq)+3H2(g) If you place 2.05 g of aluminum in a beaker with 185 ml of 1.35 M KOH, will any aluminum reamin. What mass of KAl(OH)4 will be produced
While 0.56 g of Na(s) reacts with excess F2(g) to form NaF(s), 13.8 kJ of heat is evolved at standard-state conditions. Define what is the standard enthalpy of formation (H) of NaF(s)
dilute to mark with water and mix. (You will need the extra volume of this most concentrated solution for further studies.) Record your actual standard concentrations accounting for the dilution as Cstd1, Cstd2, Cstd3, and Cstd4, respectively.
Presume 1.087g of magnesium is heated in air. Explain what is the theoretical amount of magnesium oxide that must be produced? Compute the percent by mass of molybdenum as well as sulfur in Mo2S5.
Question- You have 875 mL of an 0.51 M acetic acid solution. What volume (V) of 2.30 M NaOH solution must you add in order to prepare an acetate buffer of pH = 4.33? (The pKa of acetic acid is 4.76.)
