So one mole of H 2SO 4 weighs 98 grams. Now use this conversion to
find the mass for 42 moles:
Grams of H 2SO 4 = 42 moles x (98 grams/1mole) = 4.12 kg
So there are 4.12 kg of H 2SO 4 in 42 moles. (That’s a lot – you’d never
use that much!)
10. Redox reactions involve electron transferring between atoms.
Hydrogen ions (protons) transfers are found in acid-base reactions.
11. Grind up the reactants into a fine powder, swirl them in a
minimal amount of water, raise the temperature of the water, and add
an appropriate catalyst.
Here’s why: Increasing the temperature will usually increase the rate
of reaction, as the higher the temperature of the reactants, the more
kinetic energy is in the system. Putting the reactants in a solution
allows them to not only react on all sides of the substance but also
allows the reactants the most amount of freedom to mingle and react
with each other. A higher concentration of the reactants increases the
reaction rates because the number of collisions increase. Fine powders
react more quickly than large chunks because there’s more area
exposed to react when a substance is in powder form, so surface area
plays a role in the reaction rates as well. To speed up a reaction
without altering the chemistry of the reaction involves adding a
catalyst.
