Isopropyl alcohol (c3h7OH) burns in air according to this equation: 2C3H7OH + 9O2 -> 6CO2 + 8H2O
a) calculate the moles of oxygen needed to react with 3.40 mol C3H7OH
b) find the moles of each product formed when 3.40 mol C3H7OH reacts with oxygen

What is impossible to do with a hypothesis

The student repeated the experiment using a higher concentration of acid. the same volume of acid and the same mass of magnesium ribbon were used. what volume of hydrogen gas would have been produced after 60 seconds?

Suppose a pair of chemical compounds a and b can react in two different ways: a + b -> c reaction 1 gives product c. a + b -> d reaction 2 gives product d. the following facts are known about the two reactions: . reaction 1 is endothermic and reaction 2 is exothermic. if a reaction vessel is charged (filled) with a and b , then at first d is produced faster than c. use these facts to sketch a qualitative reaction energy diagram for both reactions. note: because these sketches are only qualitative, the energies don? t have to be exact. they only have to have the right relationship to each other. for example, if one energy is less than another, that fact should be clear in your sketch.
