Answer:
C: The actual yield depends on the reaction conditions, but the theoretical yield varies only with reactant amounts
Explanation:
Looking at the options, the correct one is Option C because the actual yield usually depends on the conditions of the reaction, while the theoretical yield usually varies with only the amount of reactant.
Answer: C excess reactant
Reason: It is not catalyst because catalyst are not consumed. It is not product because it was one of the reactants. It is not limiting because there was excess left over.
Answer:
The answer to A would be iv) 0.01 M HCL, but I'm not sure what the answer to part B is. Hope this helps.
Explanation:
Valence electrons form bonds to create molecules and compounds because A. they are weaker than the electrons found closer to the nucleus.
A better way of saying it is that the valence electrons are <em>less strongly attracted</em> to the nucleus.
All electrons have the same size, but the <em>orbitals</em> they occupy have different sizes.
Answer:
The mean velocity is 13 ft/s.
The Reynolds number is 88,583 and it is dimensionless.
Explanation:
We have water flowing in a pipe of 1.05 in diameter.
The density is ρ=62.3 lb/ft and the viscosity is 1.2 cP.
The mean velocity can be calculated as
The Reynolds number now can be calculated for this flow as
being ρ: density, u: mean velocity of the fluid, D: internal diameter of the pipe and μ the dynamic viscosity.
To simplify the calculation, we can first make all the variables have coherent units.
<em>Viscosity</em>
<em>Diameter</em>
Then the Reynolds number is
