Classify each substance as a pure substance or a mixture. If it is a pure substance, classify it as an element or a compound. If it is a mixture, classify it as homogeneous or heterogeneous.
b. carbon dioxide
d. vegetable soup
Step 1 of 3
Solution 37E: All digits of a measurement including uncertain number are called significant figures. Significant figures = all certain digits + one uncertain digit The rules for determining the significant figures are (i) Zeros between nonzero digits are always significant (ii) Zeros at the beginning of a number are never significant. (iiI) Zeros at the end of a number are significant if the number has a decimal point (a) 601 kg, There are three significant figures. This is because , zero is between the non zero digits. So zero is also a significant figures along with non zero digits. (b) 0.054 s Here significant figures are two. This is because, zero in the beginning is not significant. So it is counted only two non zero digits as the significant figures. (c) 6.3050 cm Here significant...
