Answer:
Option C is false statement. The half life of a second order reaction is not dependent on concentration.
Explanation:
Half life of a reaction is defined as the amount of time which is required for a reactant concentration reduced by half comparison to its initial concentration.
Half life of a second order reaction is depend on the initial concentration of a reaction, in contrast to 1st order reaction.
Explanation:
answer: uuuuh so sorry if i get wrong so basically they will practice measuring different liquids. They will use a container called a graduated cylinder to measure liquids. Graduated cylinders have numbers on the side that help you determine the volume. Volume is measured in units called liters or fractions of liters called milliliters (ml).

Answer:
Explanation:
250 cm^3 of 0.2 moldm-3 H2SO4 can be prepared from 150cm^3 of 1.0 moldm^-3 by dilution.
150cm^3 of the 1.0 moldm^-3 stock solution is measured out using a measuring cylinder and transferred into a 250 cm^3 standard volumetric flask and made up to mark. The resulting solution is now 250cm^3 of 0.2 moldm-3 H2SO4.
