Answer:
True
Explanation:
For every action force there is a reaction force according to Newtons third law so all forces produce motion.
A) a disk formed of long trails of stars coiled into a spiral
The statement correct about bonding is the release of energy in bond formation, and is exothermic. Thus, option C is correct.
The bonds have been defined as the sharing of electrons between atoms for the stabilization and forming compounds. The formation and breaking of the bond results in the absorption and release of the energy.
<h3>Endothermic and Exothermic reaction</h3>
The reaction in which the energy has been released has been termed as exothermic reaction. The reaction in which energy is absorbed is termed as endothermic system.
The bonds are stable, and to break the bond energy has to be provided to the system. The energy will result in the delocalization of electrons and thereby breaking of bonds.
Since energy has been absorbed by the system during breaking of bonds, the reaction has been an endothermic reaction.
The formation of the bond has been releases the energy in the system and is an exothermic reaction. Thus, option C is correct.

Answer:
Bottle 2 shows the vinegar has a molarity of 2M acetic acid
Explanation:
2M of acetic acid has higher concentration of acetic acid as compared to other vinegar. In 2M of acetic acid is equals to 120 gram of acetic acid in 500 ml of water which is quiet higher than other concentration of acetic acid in vinegar which is 4%. So Mr. Holmes has to use 2M of acetic acid which will produced high intense eruption in the volcano and win the national science fair contest.
Answer:
They need to use energy from other tress to survive so that they can do basic functions, like absorbing nutrients from the ground, and growing back leaves. They don't have chlorophyll, so they need that energy to do the functions I mentioned above.
Explanation: Hope this helps!
