A solid with a density of 3.57g/mL and mass of 19.5g is added to a graduated cylinder that contain 23.2mL of water. What is the
NNADVOKAT [17]

Answer:

Volume of liquid = 28.7 mL

Explanation:

Given data;

Density of solid = 3.57 g/ml

Mass of solid = 19.5 g

Volume of water = 23.2 mL

Total volume when solid is dropped into graduated cylinder= ?

Solution:

Density = mass/ volume

v = m/d

v = 19.5 g/ 3.57 g/ml

v = 5.5 mL

Volume of liquid = volume of water + volume of solid

Volume of liquid = 23.2 mL + 5.5 mL

Volume of liquid = 28.7 mL

To dissolve one substance in another, thus forming a solution, three things must occur: The forces holding solute particles toge
aniked [119]

To dissolve one substance, attractions between solute and solvent particles must be formed, steps involved are:

<h3><u>Formation of a solution:</u></h3>
  • A physical process, not a chemical one, takes place when a solute and a solvent combine to produce a solution.
  • In other words, by applying the right separation techniques, both the solute and the solvent may be recovered in chemically unaltered forms.
  • It is claimed that two substances are entirely miscible when they combine to create a single homogenous phase in all ratios. Water and ethanol mix well, much like different gas combinations do.
  • When two substances, like oil and water, are fundamentally insoluble in one another, they are said to be immiscible.
  • We have already talked about several examples of gaseous solutions, such as the atmosphere of Earth.
  • Thus, a system that has two or more compounds homogeneously (in a single phase) dissolved in it is called a solution. It is the homogenous mixture formed when a solute dissolves in a solvent.

Why do animals need carbohydrates in their diets
Sever21 [200]

Answer:

Carbohydrates are energy-providing feed components composed of carbon, hydrogen, and oxygen. They should make up about 75 percent of an animal's diet. The energy they provide powers muscular movements. Carbohydrates also produce the body heat that helps keep the animal warm.
