Answer:
6.98%
Explanation:
% error= |experimental value - actual value|/actual value × 100
Experimental value= 4.6 cm
Actual value= 4.3 cm
% error = |4.6-4.3|/4.3 × 100
% error = 6.98%
True.
A mixture is composed of two or more pure substance that are physically combined but are not combined chemically and thus no electrons (of their atoms) are involved.
The primary properties of a mixture include:
1. The components of a mixture are easily separated
2. The components each keep their original properties.
3. The proportion of the components may vary.
There are two main categories of mixtures:
1. Heterogeneous mixtures - substances are not evenly distributed e.g. oil and water mixture
2. Homogeneous mixtures - substances are evenly distributed throughout the mixture e.g. salt water, air.
mass spectrum of tertiary butyl chloride having overall mass as 92 m /Z for Cl35 and 94 m /Z for Cl37. The major peak at 57 m /Z for the removal of chlorine - 37 radical whereas other peak appear at 77 m /Z after removal of a methyl radical.
Ir of tertiary butyl chloride appear majorly at 3000 Cm^-1 whereas other small peaks appear between 1400- 1550 Cm-1
