Answer:
mass = 58.944 g
Explanation:
Given data:
Number of moles of SO₂ = 0.921 mol
Mass of SO₂ = ?
Solution:
Formula:
Number of moles = mass/ molar mass
First of all we will calculate the molar mass.
SO₂ = 32 + 16×2 = 64 g/mol
Now we will put the values in formula.
Number of moles = mass/ molar mass
0.921 mol = mass /64 g/mol
mass = 0.921 mol × 64 g/mol
mass = 58.944 g

Answer:
Explanation:
Hermione is pretty smart. She realizes that, according to Dalton's Law of Partial Pressures, each gas exerts its pressure independently of the others, as if the others weren't even there.
She shows Ron how to use the Ideal Gas Law to solve the problem.
pV = nRT
She collects the data:
V = 1.00 L; n = 0.0319 mol; T = 25.0 °C
She reminds him to convert the temperature to kelvins
T = (25.0 +273.15) K = 298.15 K
Then she shows him how to do the calculation.
Isn't she smart?
The answer to this question would be: calcium ions to diffuse into the cell.
The presynaptic neuron would need to release neurotransmitter to the postsynaptic neuron. To do this, the action potential will cause calcium ion diffuse into the cell causing the vesicle with the neurotransmitter to migrate to the cell membrane and release its content.
Answer:
all these are physical properties except release of heat so it's probably heat energy given off
