<span>Take the inversion of density: 1mL/13.6 g and multiply it by the conversion factor 453.6 g/ 1 lb and the given 5.00 lb. Units for mass (grams) and units for weight (lbs) cancel leaving only units of volume. I believe it should be 167 mL or 0.167 L</span>

Answer:

<h3>The answer is 41.05 %</h3>

Explanation:

The percentage error of a certain measurement can be found by using the formula

P(\%) =  \frac{error}{actual \:  \: number}  \times 100\% \\

From the question

actual density = 0.95 g/mL

error = 0.95 - 0.56 = 0.39

So we have

p(\%) =  \frac{0.39}{0.95}  \times 100 \\  = 41.0526315...

We have the final answer as

<h3>41.05 %</h3>

Hope this helps you

<h3>Answer:</h3>

Trough

<h3>Explanation:</h3>

We need to answer the following questions

What is a wave?

  • A wave refers to a transmission of a disturbance from one point to another. It involves transfer of energy from the source to other points.

What are the major types of wave?

  • Waves may be classified as longitudinal waves or transverse wave based on the vibration of particles relative to the direction of transmission.

What is a transverse wave?

  • A transverse wave is a wave in which the vibration of particles is perpendicular to the direction of transmission of the wave.
  • This type of wave contains highest points known as crests and lowest points known as troughs.

Explain why aluminum does not react with potassium nitrate (KNO3) although it reacts with copper nitrate
Ratling [72]

Answer:

Potassium is more reactive than aluminium, so no reaction takes place. But aluminium is more reactive than copper, so it replaces the copper in copper nitrate

<h3>Explanation:</h3>

More reactive metal compound + less reactive metal

-> no reaction

However

Less reactive metal compound + more reactive metal

-> more reactive metal compound + less reactive metal

This is called substitution reaction where the more reactive metal replaces the less reactive metal in the compound.
