"In chemistry and physics, atomic theory is a scientific theory of the nature of matter, which states that matter is composed of discrete units called atoms. ... In fact, in certain extreme environments, such as neutron stars, extreme temperature and pressure prevents atoms from existing at all."
Answer:
Stars which never disappear below the horizon are called <u>circumpolar</u> stars.
Compete Question:
What mass of CDP (403 g mol−1) is in 10 mL of the buffered solution at the beginning of Experiment 1?
Passage: "16 mmol of CDP in 1 L of buffer"
Answer:
6.4 × 10-2 g
Explanation:
we are given from the question that 16 mmol of CDP is in 1 L of buffer
this mean that we have 
moles of CDP in 1 liter of buffer.
so the mass of CDP in one liter of buffer will be calculate as,
mass of CDP = × 403g mol−1
= 
= 6.4 g/L
But because the question
asks us about the mass of CDP in 10 mL of solution, we will go further to calculate it like this:
6.4 g/L × 10 mL
6.4 g/L × 0.01 L = 
A climograph is a dual-purpose graph, showing two different kinds of information. A bar graph shows how much precipitation a given place receives during a period of time. A line graph shows the temperature conditions for the same place during the same period of time.
A mixture can be separated by looking at the physical properties of the components of the mixture.
Since salt is soluble in water, it can be added to the mixture to dissolve the salt.
The bar magnet is now introduced in order to remove the iron filings since they are attracted by a magnet.
The solution is filtered to separate the sand from the salt solution.
Lastly, the salt solution is heated to dryness to drive away the water and obtain the solid salt.
Hence the mixture has been separated into its components using their individual physical properties. Option A is the correct answer.
