The statement “The mechanical advantage of a compound
machine is equal to the one simple machine that has the greatest mechanical
advantage” is TRUE. I am hoping that this answer has satisfied your
query and it will be able to help you in your endeavor, and if you would like,
feel free to ask another question.
<span>6.38x10^-2 moles
First, let's determine how many moles of gas particles are in the two-liter container. The molar volume for 1 mole at 25C and 1 atmosphere is 24.465 liters/mole. So
2 L / 24.465 L/mol = 0.081749438 mol
Now air doesn't just consist of nitrogen. It also has oxygen, carbon dioxide, argon, water vapor, etc. and the total number of moles includes all of those other gasses. So let's multiply by the percentage of nitrogen in the atmosphere which is 78%
0.081749438 mol * 0.78 = 0.063764562 mol.
Rounding to 3 significant figures gives 6.38x10^-2 moles</span>
Answer:
Protons and neutrons are found in the nucleus of the atom.
Explanation:
Protons and neutrons are found in the nucleus of the atom, while electrons are outside of the nucleus.
The reaction of formation of sulfur trioxide SO₃ from sulfur dioxide SO₂ is very slow because rate of reaction is very slow at room temperature.
WHAT IS REACTION FORMATION ?
Reaction Formation is the fixation in consciousness of an idea, affect, or desire that is opposite to a feared unconscious impulse.
WHAT IS RATE OF REACTION ?
The Rate of Reaction or Reaction Rate is the speed at which reactants are converted into products. When we talk about chemical reactions, it is a given fact that rate at which they occur varies by a great deal. Some chemical reactions are nearly instantaneous, while others usually take some time to reach the final equilibrium.
Thus, the reaction of formation of sulfur trioxide SO₃ from sulfur dioxide SO₂ is very slow because rate of reaction is very slow at room temperature.
