Answer:The changes around us that involves chemistry is burning,cooking,rusting,and rotting.
Explanation:
B) Dalton's law
Explanation:
Dalton's law of total pressure of mixture of gases is the sum of the partial pressure of the gases that makes them up.
The law states that "the total pressure of a mixture of gases is equal to the sum of the partial pressures of the constituent gases".
Pt = P1 + P2 + P3 .....Pn
where:
Pt is the total pressure of gas mixture
P1,P2,P3,...Pn = partial pressure of gases 1,2,3...n respectively
A partial pressure is the pressure a gas would exert if it occupies the volume of a container alone

Answer:
the equivalence point occurs when the amount of added titrating substance is stoichiometrically equivalent to the present amount of the analyte or substance to be analyzed in the sample
Explanation:
in the equivalence point, we have:
- moles of acid = moles of base
⇒ (Volume * Concentration )acid = (Volume * Concentration)base
As can be seen in the equation, at the point of quivalence there is complete salt formation, so the pH is calculated through the salt, therefore, it is not significant how strong or weak the base or acid is in the titration.
