Answer
Brief Explanations:
Matter is anything that has mass and takes up space. Examples of non - matter include light and heat as they have no mass and do not occupy physical space in the traditional sense.
Answer:
Matter is anything that has mass and takes up space. An example of something that is not matter is light.
| Particle Structure | Compressibility | Motion of Particles | Shape | Volume | |
|---|---|---|---|---|---|
| Solid | Closely packed in a regular pattern | Low | Vibrate in fixed positions | Definite | Definite |
| Liquid | Closely packed but not in a regular pattern | Slightly compressible | Move around each other | Takes the shape of the container | Definite |
| Gas | Far apart and randomly arranged | Highly compressible | Move freely in all directions | Takes the shape of the container | Takes the volume of the container |
Brief Explanations:
A physical property can be observed or measured without changing the substance's chemical identity. A chemical property describes how a substance changes into a new substance during a chemical reaction. Examples of physical properties are color (e.g., copper is reddish - brown) and melting point (e.g., ice melts at 0°C). Examples of chemical properties are flammability (e.g., wood is flammable) and reactivity with acids (e.g., zinc reacts with hydrochloric acid).
Answer:
A physical property can be observed or measured without changing the chemical identity of a substance. Examples: color, melting point. A chemical property describes the ability of a substance to undergo a chemical change. Examples: flammability, reactivity with acids.
Brief Explanations:
An intensive physical property does not depend on the amount of matter present, like density (e.g., the density of gold is the same whether it's a small nugget or a large bar) and boiling point (e.g., water boils at 100°C regardless of the volume). An extensive physical property depends on the amount of matter present, such as mass (e.g., a large block of iron has more mass than a small piece) and volume (e.g., a large bucket of water has more volume than a small cup).
Answer:
An intensive physical property does not depend on the amount of matter, e.g., density, boiling point. An extensive physical property depends on the amount of matter, e.g., mass, volume.
Brief Explanations:
In a layered system, the least dense substance floats on top and the most dense sinks to the bottom. So, corn oil is the least dense as it is on top and syrup is the most dense as it is at the bottom.
Answer:
The least dense substance is corn oil. The most dense substance is syrup.
Explanation:
Step1: Identify given values
Given $m = 18.0\ g$ and $v=3.2\ mL$
Step2: Use the density formula
$d=\frac{m}{v}=\frac{18.0\ g}{3.2\ mL}$
Step3: Calculate the density
$d = 5.625\ g/mL$
Answer:
Given: $m = 18.0\ g$, $v = 3.2\ mL$; Formula: $d=\frac{m}{v}$; Plug - in: $d=\frac{18.0\ g}{3.2\ mL}$; Answer with UNIT: $5.625\ g/mL$
Explanation:
Step1: Identify given values
Given $m = 11.25\ g$ and $d = 11.9\ g/mL$
Step2: Rearrange the density formula for volume
$v=\frac{m}{d}$
Step3: Plug in the values
$v=\frac{11.25\ g}{11.9\ g/mL}$
Step4: Calculate the volume
$v\approx0.945\ mL$
Answer:
Given: $m = 11.25\ g$, $d = 11.9\ g/mL$; Formula: $v=\frac{m}{d}$; Plug - in: $v=\frac{11.25\ g}{11.9\ g/mL}$; Answer with UNIT: $0.945\ mL$
