Answer:

D . A substance with a pH of 8

Explanation:

pH stands for <em>"Potential for Hydrogen." </em>This is an indicator of a solution's acidity or alkalinity. It is also used to tell <em>which chemicals are great for cleaning. </em>

pH 7 and pH 8 are both considered<em> "neutral pH,"</em> thus, solutions with these pH are often used as<em> dishwashing detergents </em>because they do not destroy the surfaces of objects. However, pH 8 is said to be<u> more alkaline in nature</u>. This allows it to destroy the residues, such as <em>fats and oils</em>, in pots and pans. It is the<em> pH of baking soda.</em>

Forces and Motion:Question 1
defon

Answer:

Velocity = 12 km/h

Explanation:

Velocity can be defined as the division between distance traveled and the time it took for that distance to be traveled:

  • Velocity = Distance / Time

With the above information in mind, we can calculate the velocity of the bicycle:

  • Velocity = 18 km / 1.5 h
  • Velocity = 12 km/h

Thus the velocity of the bicycle is 12 kilometers per hour.
