Answer:
Explanation:
Mixtures are impure substances with the following properties:
- Their composition is indefinite i.e they consisit of two or more elements or compounds in any proportion by mass.
- Their constituents retains their identity i.e physical properties are retained.
- They can easily be seperated by physical methods into their constituents.
It is important to seperate materials from mixtures because mixtures do not undergo chemical changes when they combine. This implies that they can easily be seperated using simple seperation techniques with the constituents still retaining their properties.
Answer: Significant figures are important to show the precision of your answer. This is important in science and engineering because no measuring device can make a measurement with 100% precision. Using Significant figures allows the scientist to know how precise the answer is, or how much uncertainty there is.
Explanation:
Answer: Explanation:
When supply and demand for a product increase simultaneously, we cannot predict the market clearing price, but know that the equilibrium quantity will increase.
NB: We cannot predict the market clearing price because no adequate information such as government policy is provided. such information would likely affect the market clearing price either positively or negatively.
P.S: This is a business question.
