3. If 500.0 ml of a gas are collected at a pressure of 740.0 mmHg, what volume will the gas
occupy at standard pressure? Assume the temperature of the gas is held constant?

Engineers have contribute to society in many ways like making the technology we use today or any type of power energy material

C) electrons encircling a nucleus with neutrons and protons

Reaction involved in present system is :   c12h22o11 + h2o → 2 c6h12o6the reaction system is obeying following rate law:   rate = k[c12h22o11]thus, it is a first order reaction.now, for 1st order reactionrate constant (k) =  given: initial conc. = 3.0 g, final conc. = 2.7 g, t = 2.5 h∴rate constant (k) =  ∴ k = 0.04215 h-1now, for 1st order reaction, half life = 0.693/k = 0.693/0.04215 = 16.4 hthus correct answer is option b
