Which statement best applies collision theory to preventing a dangerous reaction from occurring? store the reactants together at a low pressure. keep all sparks or flames away from the reactants. store the reactants together at a low temperature. keep the reactants in separate containers.

According to collision theory, to preventing a dangerous reaction from occurring, the best is to keep reactants in separate containers (last statement).

Justification:

Collison theory states that the the reactant substances (atoms, ions or molecules) must first collide to react and form the products.

Additionally, to form the products, the collisions must meet two requirements:

Hence, the collision theory permits you preventing a dangerous reaction from occurring, by using the elemental knowledge that the substances must first collide in order to they react, and so the most effective way is to keep the reactants in separate contaners, preventing the reactants from coming into direct contact.

a:

by the combination of an unlimited number of elements

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
