Discuss how nitrogen, once fixed, enters into anabolic biochemical reaction pathways. Your discussion should include how it is eventually
0431 moles of sucrose (a sugar with a MW of 342 g/mol) are dissolved in 400.0 g of water. The solution density is 1.013 g/mL and you can assume that the density of pure water is 1.00 g/mL. What is the molality of this solution
how do you prepare 50mL of 0.15M malonic acid, 0.020M manganese sulfate and 0.5% (w:v) starch from malonic acid CH2(COOH)2 reagent grade, starch (soluble), and manganese (II) sulfate monohydrate, MnSO4.H2O (s)?
A solution has a hydronium ion concentration of [H3O+] = 5.3 x 10^-4 Determine the pH of this solution.
Convert lb mol CaC2 feed to lb and calculate lb inerts added. The total lb solids in the slurry is then the sum of the Ca(OH)2 plus inerts. In calculating the water added, remember that some is consumed in the reaction.]
