Answer:
50 g Sucrose
Explanation:
Step 1: Given data
- Concentration of the solution: 2.5%
Step 2: Calculate the mass of sucrose needed to prepare the solution
The concentration of the solution is 2.5%, that is, there are 2.5 g of sucrose (solute) every 100 g of solution. The mass of sucrose needed to prepare 2000 g of solution is:
2000 g Solution × 2.5 g Sucrose/100 g Solution = 50 g Sucrose
Nuclear reactions involves a change in the nucleus of the atom meaning that an element can entirely be converted into another element where the atom change in atomic number, mass and type.
Based on this, the correct answer is:
<span>D. Elements are created that differ from the reactants.</span>
0.2346g of C8H18/114.224g x 6.022 x 10^20 mol of C8H18 =
0.01237 or 1.237x10^20 mol of C8H18.
B) are compressible.
Explanation:
The three members of the noble gas family are all compressible in nature and they are monoatomic gaseous molecules.
There are three states of matter which are:
Solid
liquid
Gases
Gases are random matter that have not fixed shape and volume. This implies that they can easily fit into any container they are placed into. Their state of motion is randomized and they are free to move in all directions colliding with one another and the walls of their container.
When pressure is applied to them, they get compressed and takes up the shape of any vessel they are in.
Gases are the only compressible state of matter.

Answer:
Thermoplastics and thermosets
Explanation:
The two key categories of plastic are thermoplastics and thermosetting plastics (thermosets). Thermoplastic products have the ability to be continually softened, melted and reshaped/recycled, for instance in injection molding or extrusion resins. However, thermoset products do not have this property.
