Various options are proposed and evaluated towards a water management strategy, explain briefly three of available conceptual tool when devising options and discuss in detail the broad categories of factor that will enable the option to be evaluated?
Please show me how work it out above problem
describe how will you prepare a supersaturated solution of potassium nitrate in water.
Calculate the enthalpy of the reaction: 2NO(g) + O2(g) --> 2NO2(g) given the following reactions and enthalpies of formation: 1/2 N2(g) + O2(g) --> NO2(g), delta H *A = 33.2 kJ 1/2 N2(g) + 1/2O2(g) --> NO(g), delta H *B= 90.2 kJ
Compute the stoichiometric air/fuel ratio for burning compressed natural gas (CNG) if we presume that CNG is CH4.
Depict the formula of the protein leucine from previous to it is oxidized to what it turns into after being oxidized. On the hand, illustrate the molecular formula indicating how many oxygen atoms are needed to oxidize leucine
when a blue copper(II)nitrate solution is mixed with a colorless solution of sodium sulfide
Find a corresponding criterion for processes at constant V and T. The new thermodynamic variable that is used to express this criterion is called the Helmholtz free energy
We did the ice cream experiment by means of NaCl and ice to drop the freezing point as well as create ice cream. Explain what are the 2 thermo chemical equations involved? One would be NaCl(s)--> Na+(aq) + Cl-(aq). Explain what would other be?
if a sample of gas at 25.2 C has a volume of 536 mL at 637 torr, what will its volume be if the pressure is increased to 712 torr.
One metric ton (1000 kg) of coal is required to produce 7.3 MW-hr of electrical energy. In 1993, the Thomas Hill power plant (a small, coal-fired plant supplying rural electric cooperatives) produced 7100000.0 MW-hr.
If the enery of the products is less than the energy of reactants then the speed of collision has no effect on the rate of the reaction. B) The energy of the collision of molecules must be great enough to overcome the bond energy of the products.
calcium malonate, the salt of malonic acid, is found in beetroot and is known as an inhibtor of the citric acid cyle. if a sample of beetroot disolved in water has a pH of 8.20,
Iron(II) chloride (melting point 677°C) and potassium chloride (melting point 776°C) form the compounds KFeCl3 and K2FeCl4 at elevated temperatures.
