The answer is: all true
<span>A. As the pressure of the gas increased, the volume of the gas decreased.
It is clear that if you compare the data on the left side. When the pressure increased the volume is decreased.
B. For all pairs of data of pressure and volume, P • V was appoximately the same.
The pressure is inversely related to the volume. You can take two data to prove it. Let use the first and second data
V * P= 1.03 * 50= 51.5
</span>V * P= <span>1.08 * 47.5= 51.3
C. For all pairs of data of pressure and volume, P • V mr001-1.jpg k for the same value k.
D. The regression equation was of the form V = kP–1 (which is the same as V = k/P).
The value of k can be expressed as k= P*V. If the equation is turned around, it could be expressed as V= k/P
The value of k is constant on different data, proved by the calculation on the second statement above. The value of k should be around 51.5

The sediment will most likely get smaller and smoother due to the continuous scrpaing against other things.
Aluminum is a substance because it is a metal on the periodic table.It is also known to be a pure substance because it can't be broken down more than it already is. I would definitely check that answer though. XD ~JOLLY~

Answer:
Bromine is a very reactive element. While it is less reactive than fluorine or chlorine, it is more reactive than iodine. It reacts with many metals, sometimes very vigorously. For instance, with potassium, it reacts explosively.
Explanation:
Answer:
C, 3.00 moles
Explanation:
First, balance the equation.
4Al + 3O2 ---> 2Al2O3
From the balanced equation, assuming Al is limiting, the mole ratio of Al:Al2O3 = 4:2 = 2:1,
meaning every 2 moles of Al used, produces 1 mole of Al2O3.
So, since 1.5 moles of Al2O3 is produced,
the no. of moles of Al used = 1.5 x2
= 3.0 moles
= C
