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.
Hi there! I had the same question on my test as well!
The correct answer is (A) Homogeneous mixture!
I hope I helped you, and I am 100% this is the right answer!
Each mole has 6.02 x10^23 atoms so they have same atoms
Answer:
Explanation:
The glass (which does not crystallize even though it is accepted) of a window is NOT a mineral, since it is neither a substance of natural origin (although it is manufactured from natural components) nor does it have a defined crystalline structure, that is, the atoms they are not arranged in an orderly and regular way along axes and planes forming flat faces that keep a symmetry.
Remember that a mineral is defined as a solid, inorganic, homogeneous substance, of natural origin, with a crystalline structure and a determined and well-defined chemical composition within narrow margins and that has regular and characteristic physical properties.
