Which of the following best describes solids?A. Solids are low in density and compressible.
B. Solids are high in density and compressible.
C. Solids are low in density and incompressible.
D. Solids are high in density and incompressible.
Answers
Answer: Option (D) is the correct answer.
Explanation:
Solids are the substances whose molecules are closely packed together due strong inter molecular forces between them. This causes the solid to have a fixed shape and volume.
Whereas density is mass divided by per unit volume.
Mathematically, Density =
Since, density is proportional to mass. So, more is the mass that is, more is the number of molecules held together by strong forces more will be its density.
Therefore, we can conclude that the statement solids are high in density and incompressible, best describes solids.
Multiple answers could be chosen, just due to the fact that a solid is nothing more than just an object that cannot change it's physical shape into an object; just as water would. a solid can have a low density; such as paper, plastics, or even just a piece of wood.
But think of a block of ice. You can break it, and crush it. It cannot be formed into any other shape. If you did break it, it only would make more ice fragments. And it's next phase is a liquid; if it were to be melted.

KOH = 56.0 g/mol
Number of moles of KOH :
5.93 / 36.5 => 0.1624 moles
KOH + HCl = KCl + H₂O
1 mole KOH --------------> 1 mole HCl
0.1624 moles KOH ----> ?
moles HCl = 0.1624 x 1 / 1
= 0.1624 moles of HCl
V ( HCl ) = moles / molarity
V(HCl) = 0.1624 / 0.183
V (HCl) = 0.887 L x 1000 = 887 mL

Final answer:
A single replacement reaction is a type of chemical reaction in which one element replaces another in a compound. A common example of this is when zinc replaces hydrogen in hydrochloric acid to create zinc chloride and hydrogen gas.
Explanation:
A single replacement reaction is a chemical reaction in which one element replaces another element in a compound. This type of reaction can be represented as follows: A + BC -> AC + B. In this equation, 'A' is the single element that replaces 'B' in the compound 'BC', forming the new compound 'AC' and releasing 'B' as a separate element.
For example, one common single replacement reaction occurs when zinc replaces hydrogen in hydrochloric acid to form zinc chloride and hydrogen gas. This reaction can be written as: Zn + 2HCl -> ZnCl2 + H2.

Answer: from the soup to the ice
Explanation: The heat energy from the soup truly transfers to the ice cube when you put it in a bowl of hot soup. An object with a greater temperature will always transfer heat to an object with a lower temperature. In this instance, the hot soup has a higher temperature than the ice cube due to its higher thermal energy content. The ice cube melts as a result of the heat energy moving from the soup to it, and the soup cools as a result.
