<u>Clapping hands</u> is a best scenario that describes a transfer of mechanical energy to heat and sound energy
Explanation:
The action of clapping your hands is mechanical hence has mechanical energy. When you clap your hands you make a sound because you cause vibrations in the air around the clapping hands. This is a transformation of the mechanical energy to sound energy. You realize that clapping your hands causes your hands to get warmer. Some of the mechanical energy was also transformed into heat energy.

Answer:
The limiting reactant is the copper
Explanation:
Moles are the standard unit at which you can compare values, and copper has fewer moles than Silver nitrate, so in a reaction, it would be used up first, leaving Silver nitrate in excess.
Answer:
C
Explanation:
Alcohols are organic molecules characterized majorly by the presence of the OH group in their molecule. The OH group is majorly responsible for several of their characteristics. This include the formation of hydrogen bonds between alcohol molecules. While this makes them more inorganic than most organic compounds, comparatively the hydrogen bonding formed in alcohols is not as strong as that which is present in water.
The higher strength of the hydrogen bonding is responsible for some comparable properties. While water boils at a temperature of 100 degrees Celsius, alcohol boils at a temperature of 78 degrees Celsius. This is an evidence to the fact that hydrogen bonding in alcohol is less stronger that that in water.
