This is the chemical formula for acetic acid (the chemical that gives the sharp taste to vinegar): CH3CO2H An analytical chemist has determined by measurements that there are 8.64 moles of carbon in a sample of acetic acid. How many moles of hydrogen are in the sample? Round your answer to 3 significant digits.

Ill give brainiestif one neutron initiates a fission event that produces two neutrons in the products, how many new reactions can now be initiated? if each of the neutrons produced in the first fission event then initiates a fission event that produces one neutron in the products, how many new reactions can now be initiated by each neutron? how many neutrons in total were produced by the two fission events described?

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.

If 3 moles of a compound use 24 j of energy in a reaction, what is the a hreaction in j/mol?
