Afurnace is used in conjunction with a boiler to generate steam and electricity. methane at 25°c is used as the fuel entering the furnace. air is also added at 10.0 % excess and preheated to 100°c. ninety percent of the methane fed is consumed, the product gas contains 10.0 mole co2/mol co, and the combustion products leave the furnace at 400°c. for a basis of 1,000 mol ch4 fed/s, 1) calculate the flowrates for inlet and outlet species and 2) set up the equations and indicate the steps required to calculate the heat transfer rate from the furnace (but do not complete calculations). indicate if the following changes will increase or decrease the rate of heat transfer (assume the fuel feed rate and the fractional conversion of methane remain constant). briefly explain your answers. () increasing the temperature of the inlet air, (ii) increasing the selectivity of co2 to co formation in the furnace.

Nconcentration refers to the molar concentration of an ion in solution. it may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. for soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. for example, 1 m of alcl3 is 1 m in al3+ and 3 m in cl−. 1 m of (nh4)2so4 is 2 m in nh4+ and 1 m in so42−. part a what is the concentration of k+ in 0.15 m of k2s? view available hint(s) nothing m m part b if cacl2 is dissolved in water, what can be said about the concentration of the ca2+ ion? view available hint(s) if is dissolved in water, what can be said about the concentration of the ion? it has the same concentration as the cl− ion. its concentration is half that of the cl− ion. its concentration is twice that of the cl− ion. its concentration is one-third that of the cl− ion. part c a scientist wants to make a solution of tribasic sodium phosphate, na3po4, for a laboratory experiment. how many grams of na3po4 will be needed to produce 550 ml of a solution that has a concentration of na+ ions of 0.700 m ? express your answer numerically in grams. view available hint(s) mass of na3po4 n a 3 p o 4 = nothing g provide feedback
