Answer: no
Explanation: a compound is two DIFFERENT chemically bonded. thus two green spheres would represent a molecule
Carbohydrates, proteins, lipids, and Nucleic Acids.
Exothermic:
An Exothermic reaction is a chemical reaction that expels energy in the form of heat/light. Everything a Endothermic does not do. Pretty simple for this one
reactants → products + energy.
For future reference - Exo means release, thermic means heat.
<u>Energy is a Reactant </u>

<u>_________________________________________________________</u>
Endothermic:
An Endothermic reaction essentially is draining the heat energy from anything its its surroundings. Usually its just heat but can also be salt dissolving it water or ice melting. Another example would be frost on your windshield evaporating.
It is the exact opposite of an Exothermic reaction.
<u>Energy is a Product</u>
There are two general classifications of mixtures: homogeneous mixture and heterogeneous mixture. Since sugar dissolves in water, this is a homogeneous mixture. In other words, it is called as a solution. Furthermore, there are 3 classifications of solution: unsaturated, saturated and supersaturated. Since only a few are added to the water and all of them dissolved, this is an unsaturated homogeneous mixture.
1.199 M is the concentration of KCI in the resulting solution.
<h3 /><h3>What are moles?</h3>
A mole is defined as 6.02214076 × of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
No.of moles of KCI
= 0.599 moles
Vol.of the solution,V= 500 ml
= 0.5 liter
Molarity
= 1.199 M
Hence, 1.199 M is the concentration of KCI in the resulting solution.
