A natural gas has the following ultimate analysis by mass: H2, 23.3%; C, 74.72%; N2, 0.76%; and O2, 1.22%. The flue gases have the following volumetric analysis: H2O, 15.583%; CO2, 8.387%; O2, 3.225%, N2, 72.805%. Calculate (a) the percent theoretical air used in combustion, and (b) the dew point if the flue gases are at 2 bar.

Aforce of attraction/repulsion due to the spin of electrons what is this force?

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1

Select the correct answer from each drop-down menu. describe what happens to a carbon-11 atom when it undergoes positron emission. the decay of a carbon-11 atom _1_, and this causes it to emit _2_.options for 1: > changes a neutron into a proton> changes a proton into a neutron> is hit with a neutron> reconfigures its protons and neutronsoptions for 2: > a negatively charged electron-sized particle> a positively charged election-sized particle> two atoms and several neutrons> two neutrons and two protons
