The answer is actually false.

That statement is True

The components of a true solution consist of homogenous mixture which substance dissolved in a solvent. Later on, this components will blend with others and form new properties

hope this helps

inna [77]

The volume of a pond being studied for the effects of acid rain is 35 kiloliters (kL). There are 1,000 liters (L) in 1 kL and 10^3 microliters (mL) in 1L.

35 kiloliters ( 1000 liters/1 kiloliters) (10^3 microliters / 1liters)
=35,000,000 microliters

Ii. What is the purpose of the scientific method? (2 points)

Katena32 [7]

Explanation:

What is the purpose of the scientific method?

ans/

the goal of any scientific method is to solve a problem or to better understand an observed event.

i. What does the law of conservation of energy say?

ans/

The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another.

ii. List two different kinds of energy.

ans/

Potential energy.

Kinetic energy.

iii. What does the law say about changes energy can undergo?

ans/

The implication of the Law of Conservation of Energy is that for any energy conversion, if a certain type, or form, of energy gets reduced by a certain amount, then another type of energy must increase by the same amount.

Consider the reaction: 2HI(g) ⇄ H2(g) + I2(g). It is found that, when equilibrium is reached at a certain temperature, HI is 35.

Sliva [168]

Answer:

Kc = 0.075

Explanation:

The dissociation (α) is the initial quantity that ionized divided by the total dissolved. So, let's calling x the ionized quantity, and M the initial one:

α = x/M

x = M*α

x = 0.354M

For the stoichiometry of the reaction (2:1:1), the concentration of H₂ and I₂ must be half of the acid. So the equilibrium table must be:

2HI(g) ⇄ H₂(g) + I₂(g)

M 0 0 Initial

-0.354M +0.177M +0.177M Reacts

0.646M 0.177M 0.177M Equilibrium

The equilibrium constant Kc is the multiplication of the products' concentrations (elevated by their coefficients) divided by the multiplication of the reactants' concentrations (elevated by their coefficients):

$Kc = \frac{[H2]*[I2]}{[HI]^2}$

$Kc = \frac{0.177M*0.177M}{(0.646M)^2}$

$Kc = \frac{0.03133M^2}{0.41732M^2}$

Kc = 0.075

How would an apple, potato, and onion all taste the same?

Firlakuza [10]

Answer:

If you were to plug your nose, it would block out more than 80% of taste, causing all three items to have no taste- therefore making them taste the same.
