Answer:
<em>This type of error affects overall accuracy but does not necessarily affect precision.</em> - Systematic error
<em>This type of error affects precision but does not necessarily affect overall accuracy.</em> - Random error
<em>This type of error occurs if you use a buret that was calibrated incorrectly when it was made.</em> - Systematic error
<em>You can minimize this type of error by taking repeated measurements.</em> - Random error
Explanation:
<em>Systematic errors are errors that are attributable to instrument being used during measurement or consistent incorrect measurement during a research</em>. They are consistently and repeatedly committed during measurements and therefore affect the overall accuracy of measurements. A person committing systematic error can have precise repeated measurement but will be far from being accurate.
R<em>andom errors on the other hand has no pattern and are usually unavoidable because they cannot be predicted.</em> When sufficient replicate measurements are made, such errors are reduced to the barest minimum and usually do not affect the overall accuracy of measurements.
The combination of the of two or more elements is known as a compound.
A homogenous mixture has a uniform composition all throughout. They are
similar in terms of the amount of composition present in a solution. For
example, oxygen is diatomic, O2. So oxygen is a compound because it has 2
elements combined in it. It is also a homogenous mixture if there are a lot of
O2 gases present in let’s say tank. They only differ in the place where they
are present. A compound is a representation of one molecule whereas a
homogenous mixture is present in a a solution.
a small cavity or space in tissue, especially in nervous tissue as the result of disease.
Answer:
8.468 x 10^24.
Explanation:
We know from Avogadro’s Law that 1 mol of a gas contains 6.022 x 10^23 molecules.
So, 7.031 mol contains 7.031 x 6.022 x 10^23 = 4.234 x 10^24 molecules. Since oxygen is diatomic, the number of oxygen atoms is 8.468 x 10^24.
