C. Stirring a solute into a solvent speeds up the rate of dissolving because it helps distribute the solute particles throughout the solvent
B.The temperature of the solvent is another factor that affects how fast a solute dissolves. Generally, a solute dissolves faster in a warmer solvent than it does in a cooler solvent because particles have more energy of movement.
A. solute in solid state), temperature and amount of stirring.
Answer:
Explanation:
Where and are number of moles of product and reactant respectively (equal to their stoichiometric coefficient).
is standard heat of formation and is standard enthalpy change for reaction at
So,
or,
or,
Answer:
<h3>The answer is 103.82 moles</h3>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>103.82 moles</h3>
Hope this helps you
The effect that the following changes have on the rate of
the reaction between the gases A
and B in a container when the temperature is decreased at a constant volume
will decrease because the molecules of A and B are ineracting very slowly due
to the decrease in temperature which results to the decrease in kinetic energy.
Answer:
The Eukaryotic cell has a nucleus
Explanation:
Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.
