Number of moles = 2.00
Volume = 4.00 L
M = n / V
M = 2.00 / 4.00
M = 0.5 mol/L
hope this helps!
Answer:
"perpendicular" or at a "right angle"
Explanation:
an example of a transverse wave is the wave created by a string being moved up and down
the wave travels to the right (or left) through the string, while a particle of the string is moved up and down (in other words: if you put a mark on one part of the string, the mark would only move up and down)
since moving right is perpendicular to moving up/down, the disturbance is perpendicular to the wave motion
The reaction is of order three with respect to the reactant.
<h3>Explanation</h3>
The rate of a reaction of order n about a certain reactant is proportion to the concentration of that reactant raised to the n-th power. This is true only if concentrations of any other reactants stay constant in the whole process.
In other words, Rate = constant × [Reactant]ⁿ, Rate ∝ [Reactant]ⁿ. (The symbol "∝" reads "proportional to".)
In this question,
[4 × Reactant]ⁿ ÷ [Reactant]ⁿ = 64.
In other words, 4ⁿ = 64, where n is the order of the reaction with respect to this reactant.
It might take some guesswork to find the value of n. Alternatively, n can be solved directly with a calculator using logarithms. Taking natural log of both sides:
.
Evaluating on Google or on a calculator with support for ln (the natural log) will give the value of n- no guesswork required.
n = 3. Therefore, the reaction is of order three with respect to this reactant.
Answer:
''The relationship between air pressure, air density, or altitude? As altitude increases, pressure increases. As altitude increases, air density increases. Air pressure and density are lowest at sea level.''

Answer:
The concentration of reactants have no effect on the rate of reaction.
Explanation:
The strength of the nucleophile doesn't affect the reaction rate of an SN1 since the nuleophile is not involved in the rate determining step. Increasing the concentration of the substrate (which is a reactant) increases the rate of reaction even though increasing the concentration of the nucleopohile has no effect on the rate of reaction. The use of polar protic solvents assist an SN1 reaction hence the solvent used can affect the rate of reaction. However, temperature affects an SN1 reaction. Increasing the temperature will increase the rate of E1 elimination reaction rather than the SN1 reaction since the both are competing reactions. Lowering the temperature favours SN1 reaction. Hence the answer.
