Answer:

CH₄

Explanation:

According to Graham's law, <em>the rate of effusion of a gas (r) is inversely proportional to the square root of its molar mass (M)</em>.

Let's consider the following gases and their molar masses.

A) NH₃    17.03 g/mol

B) CH₄    16.04 g/mol

C) Ar       39.95 g/mol

D) HBr    80.91 g/mol

E) HCl     36.46 g/mol

Of these gases, CH₄ will have the greatest rate of effusion at a given temperature because it has the lowest molar mass.

eimsori [14]

Answer:

Explanation:

17. it goes from solid copper to aqueous copper:

Cu(s) --> Cu₂(aq) + 2e⁻

18. complete ionic:

Cu(s) --> Cu₂(aq) + 2e⁻

19. net ionic, must include only reacting species, so

Cu(s) --> Cu₂(aq) + 2e⁻

20. this type of reaction is dissolution reaction(redox reaction)

What is the relationship between an atom and a molecule?
musickatia [10]

Answer:

Atoms are given a different weight based on the number of protons and neutrons in the nucleus and electrons in the surrounding cloud. The same electromagnetic force that keeps a single atom together can also hold two or more atoms together to form a molecule, while numerous molecules join together to form matter.Apr 25, 2017
