Which of the following is not a reason why actual yield is less than theoretical yield?

Chemistry

Gnom [1K]3 years ago

Your answer is B, conservation of mass


Recall that percent yield is given by: %Yeild = actual yeild/theoretical yeild x100

During experiments, there are errors made:

• uncertainty in measurements

• losses of reactants and products

• impurity in reactants

• losses during separation (e.g. filtration or purification)

• Some side reactions might also happen.



Among the given options, only conservation of mass does not contribute to a lower actual yield compared to the theoretical yield.

The Spirit of America Goodyear blimp has a volume of 2.027×105 ft3.When the blimp is in operation, it is filled with helium gas.
Andru [333]
Answer: 1.027 x 10^6 g= 1027kg
In this question, you are given the volume of the blimp (2.027×10^5 ft^3) and the density of the gas(0.179g/L). To answer this question, you need to convert the volume unit into liter. The calculation would be: 2.027×10^5 ft^3 x 28.3168L/ft3= 57.398 x 10^5L= 5.74x10^6L

Then to find the mass, multiply the volume with the density. The calculation would be: 5.74x10^6L x 0.179g/L= 1.027 x 10^6 g= 1027kg

PLEASE HELP!!!!!!!!!!!!!!!!!!!
Alborosie

Based on temperature changes, the phase changes that occur in water is from a solid at A to a liquid at B, and from liquid a B to gas at C.

<h3>What is change of state?</h3>

Change of state is the process whereby a substance changes its state of matter from one form to another as as result of heat changes.

In the graph shown above, water exists in three states at different points.

  • Water exists as a solid at A
  • Water exists as a liquid at B
  • Water exists as a gas at C.

Therefore, the phase changes that occur in water is from a solid at A to a liquid at B, and from liquid a B to gas at C.

Buffers resist change in pH in a system when?
Sedbober [7]
The answer to this question is <span>b) hydrogen chloride (HCl) is added to the system. This is the only acid/base on the list. Only acids and bases have the potential to directly change pH as they contribute hydronium and hydroxide ions. Glucose, sodium chloride, and sodium bromide do not affect pH in the first place.</span>
