To express the efficiency of a reaction, you can calculate the percent yield using this formula: %yield = (actual yield/theoretical yield) x 100. A percent yield of 90% means the reaction was 90% efficient, and 10% of the materials were wasted (they failed to react, or their products were not
Answer:
If your asking for the definition of opinion, it's the belief or judgement of how you see a certain situation, example

Explanation:
The scale is pushing back up against her feet with the same amount of force but in negative direction.
This can be explain using Newton's third law of motion which states that "action and reaction are equal and opposite".
As the girl weight pulls down on the scale in a positive way with a force of 42N, the scale pulls back with an equal amount of force upward in another direction.
The net force here is zero this is why the scale is not damaged by her weight.
