Answer: There are 4.8 x 1024 hydrogen atoms in 2.0 moles of CH4
Answer:
The answer is 102.3!
Explanation:
you get this by multiplying 34.1 x 3 to get 102.3.
Wondering why you multiply 34.1 times 3?
WELLLLLLLLLLL...
when you get 1 mole of h202, you get 34.1 so if you ask for 3 moles of H202, you get 102.3!
Explanation:
The property of a substance to resist the flow of motion is known as viscosity. And, more is the density of a substance more will be its viscosity.
Whereas, lesser is the density of a substance then it is easy for the substance to move.
This means that more is the viscosity of a substance least will be its flow and when a substance has lesser viscosity then it will readily flow from one point to another.
Thus, we can conclude that the viscosities of several liquids are being compared. All the liquids are poured down a slope with equal path lengths. The liquid with the highest viscosity will reach the bottom last.
Answer:
In the given case, the atomic number of the given atom is 15, hence its nucleus contains 15 protons. The number of protons and electrons are the same in atom and that is what keeps it neutral. In the second case, the atomic number is 20. Hence, the atom will contain a total of 20 protons in its nucleus.
