A supersaturated solution holds
less solute than it normally can is false. It actually contains more solute
that it normally can. Having less solute than it normally can is an unsaturated
solution. And when it has the exact amount of solute, it is a saturated solution.
Answer:
Speed, 
Explanation:
The device which is used to accelerate charged particles to higher energies is called a cyclotron. It is based on the principle that the particle when placed in a magnetic field will possess a magnetic force. Just because of this Lorentz force it moves in a circular path.
Let m, q and V are the mass, charge and potential difference at which the particle is accelerated.
The work done by the particles is equal to the kinetic energy stored in it such that,
v is the speed with which the particles enter the cyclotron
So,
So, the speed with which the particles enter the cyclotron is . Hence, this is the required solution.
I legitimately think it's 87.3 grams
Answer:
Ba(OH)₂ requires more H₂SO₄ to reach neutralization..
Explanation:
- At neutralization, acid neutralize base to form salt and water at equivalence.
- NH₄OH is neutralized by H₂SO₄ according to the reaction:
<em>2NH₄OH + H₂SO₄ → (NH₄)₂SO₄ + 2H₂O.</em>
<em></em>
It is clear that every 2 mol of NH₄OH need 1 mol of H₂SO₄ to be neutralized.
- Ba(OH)₂ is neutralized by H₂SO₄ according to the reaction:
<em>Ba(OH)₂ + H₂SO₄ → BaSO₄ + 2H₂O.</em>
<em></em>
It is clear that every 1 mol of NH₄OH needs 1 mol of H₂SO₄ to be neutralized.
<em>So, Ba(OH)₂ requires more H₂SO₄ to reach neutralization.</em>
