A. As you make more and more of one good or service, you will also make more and more of another.
Answer:
Explanation:
Hello,
In this case, given the mass of the sample and mass of tin we can compute the mass of oxygen via:
Thus, by using the atomic bas of tin and oxygen we can compute their moles:
Next, we need to divide both moles by the moles of oxygen as those are the smallest in order to compute the subscript in the chemical reaction:
Therefore, empirical formula of the oxide should be:
Best regards.
Answer:
Accuracy of values
Explanation:
They're correct due to margin error of ±0.5 during an experiment.
1 min 15 seconds is equivalent to 75 seconds.
However the other one was 75.5 seconds.
Using the margin error of ±0.5 during recording, they're both correct.
Note : Accuracy is the closeness of agreement between a measured value and a true or accepted value. Measurement error is the amount of inaccuracy.
Precision is a measure of how well a result can be determined (without reference to a theoretical or true value). It is the degree of consistency and agreement among independent measurements of the same quantity; also the reliability or reproducibility of the result.
The uncertainty estimate associated with a measurement should account for both the accuracy and precision of the measurement.
In this case, this is an argument of who was more accurate and judging by this standard, they're both accurate but not necessarily precise since their values are not exact with each other.
Answer:
The answer will be :
In year 1869
Russian scientist named Dmitri Mendeleev
Chart called Mendeeleves periodic table
increasing atomic masses
physical and chemical properties.
Hope this Helps
Best of luck !!
