The question is: To neutralize 20ml of 0.1M HCl solution, 10ml of NaOH solution of concentration x mol/l is required. What is the value of x?
Answer: The value of x is 0.2 M.
Explanation:
Given:
= 20 mL,
= 0.1 M
= 10 mL,
= x
Formula used is as follows.

Thus, we can conclude that the value of x is 0.2 M.
Answer:
Yes, Democritus's atomic theory was correct.
Explanation:
He thought the first part of his theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given element are identical in mass and properties. The other scientists added onto his theory to show that he was correct, except Aristotle, he thought the world was made of the 4 elements: earth, wind, fire, water.
Pressurized gas is the term that is used to describe a gas that is compressed into a smaller space than it would normally occupy at Earth's surface.
Explanation:
The purpose of compressing a gas is to lessen its volume so that it can fit in a small space. Natural gas can be compressed using a compressor and the pressure of a compressed gas is 200 to 250 bars.
Pressurized gases are used in ground processing and space flight operations. Pressurized gas, also known as compressed gas is also used in fuel production and in gas pipelines.
When stored in a reservoir, care must be taken to avoid leakage as these gases compressed under high pressure are highly flammable.
