discussing factors affecting solubility

Answer 1

Answer:

Answer:

Step-by-step explanation:

Solubility can be defined as the ability of a solute (could be solid, liquid or gas) to dissolve in a solvent in order to produce a solution. There are several factors affecting solubility which includes (basically four) temperature, polarity, surface area of solute particles and pressure of gases. Generally, an increase in temperature leads to an increase in the solubility of a solute in a solvent. This is because an increase in temperature will increase the average kinetic energy of molecules in the solution which leads to increase interaction between the solute and solvent particles. There is a general saying of "like dissolve like" when discussing polarity. For example, organic solvents are used to dissolve organic solutes (just as petrol is used to wash grease off hands and surfaces). Hence, when the solute and solvent have the same polarity, solubility occurs easily, otherwise solubility may be difficult or may not even occur. A reduced/smaller surface area of the solute leads to an increase in solubility as this makes it easy for the solute particles to interact easily with the solvent. In gases, an increase in pressure increases the interaction between the gaseous molecules of the solute and the solvent, thus leading to an increased solubility. Pressure does not affect solubility in solids and rarely in liquids.

WHAT IS A POLYNOMIAL

In mathematics, a polynomial is an expression consisting of indeterminates (also called variables) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

How to Solve?

Given , we need to add $2x^2-8x-6$ and $9x^2-8$ .

So, we can write it as :

$2x^2 -8x-6+9x^2-8$

Writing like terms together:

$= 2x^2+9x^2-8x-6-8$

$=11x^2-8x-14$

Hence , the answer is $11x^2-8x-14$ .

Answer:f

(x)=x, g(x)=x3−1f(x)=x4+x3−11x2−5x+30, g(x)=2x−2f(x)=x2, g(x)=7x−1

in short ways the answer is 7x−1

If the population of a particular country is growing at 1.5 % compounded continuously, how long will it take the population to triple?

Answers

$e^(0.015t)=3$
Taking natural logs of both sides, we get
0.015t=ln 3
t = ln 3/0.015 = 73.24

The answer is 73.24 years.

Who got the answer to this ?
(4x^2+6+7)-(-8x^2-2x+6)

Answers

Answer:

12x^2+2x+7

Step-by-step explanation:

Distribute the Negative Sign:

=4x^2+6+7+−1(−8x^2−2x+6)

=4x^2+6+7+−1(−8x^2)+−1(−2x)+(−1)(6)

=4x^2+6+7+8x^2+2x+−6

Combine Like Terms:

=4x^2+6+7+8x^2+2x+−6

=(4x^2+8x^2)+(2x)+(6+7+−6)

=12x^2+2x+7

Determine whether f(x) = 4x^2 – 16x + 6 has a maximum or a minimum value and find that value.a
maximum; –10
b
minimum; –10
c
maximum; 2
d
minimum; 2

Answers

The function f(x) = 4x² – 16x + 6 has a minimum value is –10 when the value of x is 2. Then the correct option is B.

What is differentiation?

The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.

The function is given below.

$f(x) = 4x^2 -16x + 6$

Differentiate the function, then we have

$(d )/(dx) f(x) =(d)/(dx)(4x^2 -16x + 6) \n\n (d )/(dx) f(x) =8x - 16 \n$

The value of x will be

$8x - 16 = 0\nx = 2$

Then again differentiate the function, if the value comes negative then maxima and if the value is positive then minima.

$f''(x) = (d )/(dx) f'(x) \n\nf''(x)=8x - 16 \n\nf''(x) = 8\n\n f''(x) > 0$
