Answer:
ummmm... whats this supposed to mean? any answer choices
Explanation:
Answer:
5 L
Explanation:
So this problem refers to Charles's law. You would use this formula..
(Initial volume / Initial Temperature) = (Final volume / Final Temperature)
For your problem, it would look like this...

You would cross multiply and your answer would be 5L.
To reassure yourself that the answer is correct, Charles law states that the Volume and the Temperature are directly proportional. Meaning if your temperature is decreasing, your volume <u>has</u> to decrease.
The answer will be Magnesium. It is a two positive ion and it can charge electrons and protons.
Answer:
<h2>Density = 0.00026 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>

</h3>
From the question
mass of air = 1.2 g
volume = 4,555 mL
Substitute the values into the above formula and solve for the density
That's
<h3>

</h3>
= 0.0002634
We have the final answer as
<h3>Density = 0.00026 g/mL</h3>
Hope this helps you
Answer: -2m/s2
Explanation:
Using the following equation ; acceleration = Change in velocity / time
i.e a = v - u / t
where 'a' = acceleration
v = final velocity
u = initial velocity
t = time
Therefore; from the graph we have acceleration to be, 0 - 6m/s / 3s = -2m/s2
