PLZ HELP ASAP I WILL GIVE BRAINLIEST TO WHOEVER ANSWERS THIS I AM THAT DESPERATE

- If a reaction is expected to produce .75 moles of gas, how many liters of gas would that be? (no more than 3 sig figs in answer)
- A reaction produces 3 liters of hydrogen gas. How many moles of hydrogen molecules is this?
- Calculate the number of moles of Al₂O₃ that are produced when 0.58 mol of Al reacts with 0.58 mol of FeO in the following reaction: 2Al(s) + 3FeO(s) -> 3Fe(s) + Al₂O₃(s)
- Calculate the number of grams of Fe that are produced when 57 grams of FeO is reacted with excess aluminum in the following reaction: 2Al(s) + 3FeO(s) -> 3Fe(s) + Al₂O₃(s)

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

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
