PLEASE HELP ME NOW Deshawn is conducting an experiment about fermentation. He prepares six bottles. The table shows what he puts in each bottle.

bottle 1: 1 cup cold water, 1 packet yeast

bottle 2: 1 cup cold water. 1 packet yeast 2 tablespoons sugar

bottle 3: 1 cup lukewarm water, 1 packet yeast

bottle 4: 1 cup lukewarm water, 1 packet yeast 2 tablespoons sugar

bottle 5: 1 cup hot water, 1 packet yeast

bottle 6: 1 cup hot water, 1 packet yeast 2 tablespoons sugar

He swirls the bottles until the yeast dissolves and puts a balloon over the neck of each bottle. In 20 minutes,
he will check and see what has happened.

what question is being asked through this scientific investigation?

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant
