D.parent and meal choice

Step-by-step explanation:

Given : Ketut is organizing a barbecue for his parents. He knows that 13 of his mom’s friends prefer hot dogs and 9 of his dad’s friends prefer hamburgers.

To Find: He organizes a two-way table to determine what he needs to buy. Which describes the variables he can use in the first row and first column of his table?

Solution:

Since we are given that she is organizing a table of meal for parents or their friends .

So, table must include column of parents and choice of meal.

Since we are given that 13 friends is of her mom and 9 friends is of her dad and their meal choices are given .

So, the variables he can use in the first row and first column of his table is parent and meal choice.

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
