Answer:
The correct answer is - valid.
Explanation:
In this case, there is consistency in the results measures in the experiment which makes this method reliable. The consistency of a measure is referred to the reliability.
It is also given that the level of contamination of individual containers as per the average parameter of the contamination of large containers which makes this method not valid as the measurement method is how correctly it measures the true value of the parameter.
Thus, the correct answer is - method is reliable, but not valid.
Answer:
Explanation:
Of course Newton's three laws of motion are correct, because they were verified several hundred of years ago and they continue working today, for such systems. Science is accumulative. What modern physics has done is to constraint the range of validity of those laws.
Newtons first law of motion states that everybody continues in it rest or of uniform motion in a straight line unless an external force is applied on it.
Newtons second law of motion states that acceleration produced on a body by a force is directly proportional to the applied force and inversely proportional to the mass of body.
Newtons third law of motion states that to every action there is equal and opposite reaction.

In my point of view, the simple thing to do here is just to exchange the 3+ and the 2- and you will get:
Al2(CO3)3
The logic behind this is that when you have 2 Al^3+, it makes an overall charge of 6+. Additionally, when you have 3 CO^2-, it also makes an overall charge of 6- (because 3 X 2 = 6). Therefore, 6+ and 6- "cancelled" out, and you will have a neutral charge compound.
I hope you understand

Answer:
The answer is
<h2>0.99 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>
</h3>
From the question
mass of liquid = 3.75 g
volume = 3.8 mL
Substitute the values into the above formula and solve for the density
The density is
We have the final answer as
<h3>0.99 g/mL</h3>
Hope this helps you
