What do you consider to be the advantages of the numerical values? What do you consider to be the advantages of the visual repre

noname [10]

For these models there are methods such as the perturbation method which can be used to find an approximate analytical solution within a certain range. The advantage here over a numerical solution is that you end up with an equation (instead of just a long list of numbers) which you can gain some insight from.

Nada is at the supermarket. She wants to buy a chocolate and a juice that both cost $10. How much will she pay at the cashier if

Illusion [34]

Total cost = Price of juice + price of chocolate + tax = 10 + 10 + [(16/100) x 20]

R --> 2 P. Initially you start off with 0.5 M reactants and let the reaction run to equilibrium and calculate the equilibrium

Anit [1.1K]

Answer:

K still the same value

Step-by-step explanation:

given a reaction aA+bB<->cC+dD the constant K is defined as:

$\frac{C^{c}D^{d} }{A^{a}B^{b} }$

K is a constant so it won't change the value. Instead, the values of C and D are going to change. The position of equilibrium moves because of the need to keep a constant value for the equilibrium constant.

Simplify

melomori [17]

Answer: $4\sqrt{3}$

Step-by-step explanation:

For this exercise it is important to remember the following:

$i=\sqrt{-1} \\\\i^2=-1$

Given the following expression:

$-2i\sqrt{-12}$

You can notice that the radicand (the number inside the square root) is negative. Therefore, in order to simplify the expression, you need to follow these steps:

1. Replace $\sqrt{-1}$ with $i$ and simplify:
