How could you change the height of a cone so that its volume would remain the same when its radius was tripled?
V1 = (1/3)(pi)(r12)(h1) V2 = (1/3)(pi)(xr12)(h2) V1 = V2 , which means that: (1/3)(pi)(r12)(h1) = (1/3)(pi)(xr12)(h2) Divide both sides by (1/3)(pi) and you get: (r12)(h1) = (xr12)(h2) -> (r12)(h1) = x2(r12)(h2) Divide both sides by (r12) and you get: h1 = x2(h2) -> h2 = (h1)/x2 For example: Cone1: r1 = 10, h1 = 10 Cone2: r2 = 30, h2 = (10/32) = 10/9 = 1.11111111 Then to check: Volume of a cone = (1/3)(pi)(r2)(h) V1 = (1/3)(pi)(102)(10) V1 = 1047.197551 = V2 1047.197551 = (1/3)(pi)(302)(h2) h2 = 1047.197551/((900pi)/3) h2 = 1.111111111 = 10/9

When 3 moles of N2 reacts with 2 moles of H2 the number of produced moles of ammonia equal?
The reaction between nitrogen and hydrogen to form ammonia is: N2 + 3 H2 → 2 NH3 The above is the reaction for the Haber process in the industrial synthesis of ammonia. For a given proportion of 3 N2 to 2 H2 (or in ratio terms equivalent to 4.5 N2 to 3 H2), we see that H2 is the limiting reactant. Thus according to the stoichiometry of the reaction, 2 moles of H2 will form 1.33 moles of NH3.

What volume of H2 can be obtained from 100 cm3 of methane at standard temperature and pressure?
Assuming you are referring to the reaction of CH4 + H2O → CO + 3 H2, and not combustion of methane (CH4 + 2O2 ==> CO2 + 2H2O where NO H2 is formed), then ...100 cm3 CH4 = 0.1 litersmole ratio CH4 : H2 = 1 : 3 (see balance equation above).Liters H2 produced from 0.1 liters CH4 = 3 x 0.1 = 0.3 liters of H2 can be produced.
