Answer: Collide, Collision,  Collide, Proper Orientation and Energy

Explanation:

The basic premise of the collision theory is that particles must first collide if a reaction is to occur. Additionally, that collision  must be effective. To be effective, the particles must collide  with the proper orientation and the proper amount of energy.

What experimental method has allowed scientists to estimate atomic and ionic radii?
KIM [24]
The meaning of the atomic radius is a large portion of the normal internuclear separation of an atom. It isn't conceivable to deal with one atom. In any case, here internuclear remove does not mean measurement of a solitary particle but rather it implies the separation between the core of two atoms of a similar component.

A group of students is comparing the graphs of strong acid-strong base and weak acid-strong base titration curves, where the bas
erma4kov [3.2K]

The initial pH for the weak acid-strong base curve is higher than the initial pH for the strong acid-strong base curve. Hence, option A is correct.

<h3>What is a weak acid?</h3>

Weak acids are acids that don't completely dissociate in solution.

A weak acid is an acetic acid. It has a of 1.8⋅10^{-5}. Calculate how much it will dissociate in water. Since acetic acid is a weak acid so large part will not dissociate completely.

k_a=\frac{[CH_3COO^-]H^+]}{[CH_3COOH]}

B is not true, it shows the titration curve for weak/strong acid titrated with a strong base. When choosing an indicator for colourimetric titration select one so that the pH jump at the equivalence point contains the interval p±1. Phenolphthalein has a p≈9, so to decide if it is a suitable indicator check if the pH jumps from 8 to 10 at the equivalence point.

C is not true either because of the very slow reaction.
