Answer:
HEY CAN YOU POST YOUR LAST QUESTION AGAIN? CAUSE I HAVE THE ANSWER
The law of conservation of mass<span> states that </span>mass<span> in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the </span>law of conservation of mass<span>, the </span>mass<span> of the products in a chemical reaction must equal the </span>mass<span> of the reactants.
</span>
Momentum and Kinetic Energy...They both are directly proportional to the
Mass and Velocity of the object and they are the only factors which
determine them.
Hope this helps!
Answer:
These substances are called amphiprotic. Water, amino acids, hydrogen carbonate ions, and hydrogen sulfate ions are common examples.
Explanation:
A substance is amphoteric (from Greek amphoteros = "each of two") if it can act as an acid or a base.
For example, aluminum hydroxide is amphoteric because it can act as a base and neutralize strong acids.
The conclusion of the student would be that the dissolution of ammonium nitrate is endothermic.
<h3>What are endothermic reactions?</h3>
They are reactions in which heat is absorbed from the surrounding. The consequence is that the reaction mixture's temperature is always lower.
Thus, the energy of the products is always higher than the energy of the reactants in endothermic reactions.
For endothermic reactions, the enthalpy change is always positive.
