Answer:
The minimum molarity of acetic acid in vinegar according to given standards is 0.6660 mol/L.
Explanation:
4% acetic acid by mass means that 4 gram of acetic acid in 100 g solution.
Given that density of the vinegar is same is that of water = 1 g/mL
Mass of the vinegar solution = 100 g
Volume of the vinegar solution = V


V = 100 mL = 0.1 L
Moles of acetic acid =


The minimum molarity of acetic acid in vinegar according to given standards is 0.6660 mol/L.
<u>Answer:</u> The chemical equation for the given reaction is given below.
<u>Explanation:</u>
When solid calcium oxide reacts with sulfur trioxide gas to produce solid calcium sulfate, the chemical equation follows:

This is the reaction when a metal oxide reacts with non-metal oxide to produce a salt.
By Stoichiometry of the reaction:
1 mole of solid calcium oxide reacts with 1 mole of sulfur trioxide gas to produce 1 mole of solid calcium sulfate.
So here we are given that the the velocity of the proton ( V ) is 2.0 ×
meters / second, with a magnetic field of strength 5.5 ×
tesla. If they each form a right angle, they are hence perpendicular to one another, such that ....
F = q( V × B ),
F = q v B( sin ∅ ),
F = q v B( sin( 90 ) )
.... they form the following formula. Let's go through each of the variables in our formula here -
{ F = Magnetic Force ( which has to be calculated ), q = charge of proton (has charge of 1.602 ×
coulombs ), B = magnetic field }
All we have to do now is plug and chug,
F = ( 1.602 ×
)( 2.0 ×
)( 5.5 ×
) = ( About ) 1.8 ×
Newtons
Answer:
im guessing it's the second one
