En el procesos de hidratación del carburo de aluminio (Al4C3 ), se obtiene gas metano (CH4 ) e hidróxido de aluminio, Al(OH)3 , de acuerdo a la siguiente reacción: Al4C3 + H2O → CH4 + Al(OH)3
Si se dispone de 9 moles de carburo de aluminio y 6 moles. Determinar: a) Reactivo limitante y reactivo en exceso. b) Los moles de Al(OH)3 que se obtienen.​

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
