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.

Microtubular fibers that assist in the movement of chromosomes during nuclear division in conjunction with proteins, makes up the small and large organelle pieces that assemble prior to translation three-base nucleotide sequence that can complementarily pair with the functional transcript, allowing a particular material to be brought to a ribosome particular time in the cell cycle when the cell’s systems determine if the cellular conditions are appropriate to continue through the cycle time in the cell’s cycle when proteins are made and organelles are duplicated enzyme that allows proper nucleotide bonding during transcription specific dna sequence which will initiate gene transcription division of the cell’s cytoplasm specific bond that forms between two amino acids when a carboxyl group binds to a amino group three-base sequence that does not code for a particular amino acid a paired organelle which facilitates the formation of movement microtubules time in the cell’s cycle when the microtubular structures exert an equal pressure on the cell’s genetic material

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

Which of the following observations indicates that there is a small, dense, positively charged part in the center of an atom? some uncharged particles are scattered by a gold foil. all uncharged particles are attracted towards a gold foil. all positively charged particles pass straight through a gold foil. some positively charged particles bounce back from a gold foil.
