Yolanda is performing a neutralization reaction using hydrochloric acid and sodium hydroxide. Since both are clear liquids, what
Bad White [126]
I should think that Yolanda should use litmus paper throughout the reaction as its color will tell when the mixture is neutral and therefore then, when she can stop adding either the hydrochloric acid or the sodium hydroxide or if one or the other needs to be added to make the solution approach neutral. Blue litmus paper stays blue in a neutral solution, but will turn red in an acidic solution.

An elevator lifts a total mass of 1.1×103 kg a distance of 40.0 m in 12.5 s. How much power does the elevator deliver?
Harman [31]

The power delivered by the elevator is 34496 W.

<h3>What is power?</h3>

Power is the rate at which energy is used up.

To calculate the power delivered by the elevator, we use the formula below.

Formula:

  • P = mgh/t.............. Equation 1

Where:

  • P = Power delivered by the elevator
  • m = Total mass on the elevator
  • g = acceleration due to gravity
  • h = Height

From the question,

Given:

  • m = 1.1×10³ kg
  • h = 40 m
  • t = 12.5 s
  • g = 9.8 m/s²

Substitute these values into equation 1

  • P = 1.1×10³×40×9.8/12.5
  • P = 34496 W.

Hence, the power delivered by the elevator is 34496 W.
