The element that would move with the fastest average speed while in thermal equilibrium in the atmosphere is hydrogen.

<h3>What is hydrogen?</h3>

Hydrogen (H) is a colorless, tasteless, odorless, flammable and gaseous substance that is the simplest member of the family of chemical elements. Hydrogen, with the atomic number 1, is the lightest chemical element in the universe. It is also the most abundant element in the universe.

A hydrogen atom has a nucleus consisting of a proton bearing a unit of positive electrical charge; an electron, bearing a unit of negative electrical charge, is also associated with this nucleus.

Match the scientist with their scientific idea. Question 2 options: Substances combine or break apart to create new, different s
aev [14]

Answer:

1. Democritus - Matter was made of different kinds of things.

2. Bernoulli- Gases are formed from tiny particles so small you can’t see them. The particles are spread out into a certain area and move when people walk through them.

3. Priestley- Substances combine or break apart to create new, different substances.

Explanation:

1. Democritus was a philosopher who because of his immense contribution to atomic theory was regarded as the "FATHER OF SCIENCE". His idea was that matter was made of different kinds of things called which he called ATOMOS meaning ATOM.

2. Daniel Bernoulli was another outstanding mathematician and scientist who played a major part in the kinetic molecular theory of gases via his "HYDRODYNAMICA". His idea, which states that "gases are formed from tiny particles so small you can’t see them. The particles are spread out into a certain area and move when people walk through them"

was based on fluid dynamics.

3. Joseph Priestley is remarkably known for his 1774 discovery of oxygen. His findings that air is a mixture of gases and not just a substance made of one element paved the way for his idea that " Substances combine or break apart to create new, different substances".

Why couldn't you substitute 3m H2SO4 for concentrated HNO3 when oxidizing copper?
schepotkina [342]

This question seems to be an essay question from experiment. Different solution of oxidizing agent will have different strength.  Sulfuric acid or H2SO4 is weaker oxidizing agent when compared to nitric acid (HNO3). In this case, if you subtitute the H2SO4 you wouldn't be able to get the same result for the experiment.
