Density is the <u>degree of the heaviness of a particular substance. </u>
- Density can also be defined as the<u> unit mass of a substance per the substance's volume.</u>
<u />
Density is said to be the characteristic property of a pure substance because the <u>density of a pure substance</u> is <u>constant and fixed </u>
- <u>Pure substances</u> are substances that are homogenous in nature, which means they are uniform and are made up of only <u>one component.</u>
<u />
- Density is said to be the <u>characteristic property</u> of a <u>pure substance </u>because the density of a pure substance<u> is constant and fixed</u> but its <em>mass and volume can vary. </em>

Answer:
Explanation:
Base your answer to the question on the information below and on your knowledge of chemistry. At 1023 K and 1 atm, a 3.00-gram sample of SnO2(s) (gram formula mass = 151 g/mol) reacts with hydrogen gas to produce tin and water, as shown in the balanced equation below. SnO2(s) + 2H2(g) → Sn(L) + 2H2O(g) Show a numerical setup for calculating the number of moles of SnO2(s) in the 3.00-gram sample.
Answer:
The resulting structure is:
R-CH-CH2 (OH)-CH-CH2(OH)-CH-CH2(OH)-CH-...
Explanation:
It can be said that vinyl alcohol cannot be polymerized by addition polymerization, since a very unstable radical would be formed, which is not possible. Generally, it is formed by polymerization and subsequent hydrolysis of the vinyl polyacetate. According to the exercise, the structure that results with its four units can be seen that the hydroxyl groups are found in the methylene carbons
Answer:
2.
Explanation:
When you put the paper in a solution, it will turn blue if it is basic, or red if it is acidic. If it does not change color, it is fairly neutral.
N=24/12
n=2
where n= no. of moles
