Dependent is a variable who's outcome depends on another variable. independent is a variable who's outcome doesn't depend on another variable only the researchers experimenting.
hope this helps !
Answer:
225 mL of water must be added.
Explanation:
First we <u>calculate how many HCl moles are there in 516 mL of a 0.191 M solution</u>:
- 516 mL * 0.191 M = 98.556 mmol HCl
Now we use that number of moles (that remain constant during the <em>dilution process</em>) to <u>calculate the final volume of the 0.133 M solution</u>:
- 98.556 mmol / 0.133 M = 741 mL
We can <u>calculate the volume of water required</u> from the volume difference:
Answer:
<u>Deposition</u>
this is the process of a substance changing its state from gas to solid. Solid to gas is known as sublimation
Answer:
It will have no effect
Explanation:
The loss of tin oxide to evaporation will have no effect on the empirical formula of a compound.
The empirical formula of any compound is the simplest formula of that compound by which the combining atoms can be represented.
This formula is not affect by physical changes.
According to the law of constant composition "all pure samples of the same compound have the same element in the same proportion by mass".
Regardless of the mass loss or gain of any tin oxide compound, it will have the same empirical and molecular formula. The atoms are still combining in the ratio to give the product.
