Based on the molecular diagram, classify each change as physical or chemical.
Step 1 of 3
Solution 50E: All digits of a measurement including uncertain number are called significant figures. Significant figures = all certain digits + one uncertain digit There are two types of number in scientific work. (i) exact - exactly the values are known when it is measured. The values which are obtained from any measurement is completely certain value (ii) Inexact number- uncertainty in the numbers. The measured values are uncertain. The distance from Grand Rapids, Michigan, to Detroit is listed in a road atlas as 153 miles. Distance is always used to measure by using instrument.So here, distance is not an exact number. This is because, distance measurement is always uncertain and it is due to the instrumental error. Secondly, different people will make the difference to measure the distance in same measurement. This is called Human...
