Explanation:
Answer:
Option (e) should be discarded.
Explanation:
The given set of data is said to be precise if the values are close to each other. In this problem, a chemistry student is experimentally determining the boiling point of bromine.
In this case, all values are close to each other but option (e) i.e. 56.3° should be discarded to make his data precise.
Answer : C) separate the parts by their properties.
Explanation:
Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present. Trail is a mixture of various substances which do not react chemically and thus the constituents retain their chemical properties. The substances can be separated by using physical properties.
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. The elements lose their individual chemical properties. The elements can not be separated using physical means.
1. The <span>student with a measurement that might be in centimeters is A. Bill.
2. C</span><span>entimeters in 0.05 kilometers is </span>C. 5,000
solution:
0.05 km x (1000 meters/ 1 km)
= 50 meters x (100 cm/ 1 meter)
=5000 cm
The answer is C.) Pair it with a hydrogen half-cell
