Based on the given information, the compound contains no nitrogen and exhibits absorption bands at 3300 (s) and 2150 (m) cm-1. The absorption band at 3300 (s) cm-1 suggests the presence of an -OH group, while the absorption band at 2150 (m) cm-1 suggests the presence of a C≡C triple bond.
Therefore, the compound likely belongs to the functional class of alcohols (-OH) and/or alkynes (C≡C). However, we cannot make any further inferences about the compound's functional groups based on the given information.
Based on the provided infrared absorption spectrum data, the compound has absorption bands at 3300 (s) and 2150 (m) cm-1. The absorption at 3300 cm-1 with strong intensity (s) suggests the presence of an O-H bond, which is typically found in alcohols or carboxylic acids. The absorption at 2150 cm-1 with medium intensity (m) indicates the presence of a C≡C triple bond, which is characteristic of alkynes.
Therefore, the functional class(es) that the compound belongs to are alcohols or carboxylic acids and alkynes. Remember, we should not over-interpret the exact absorption band positions and only consider the evidence provided.

The question is incomplete, the complete question is;
Which of these best describes the relationship between the inner core, outer core, mantle, crust, asthenosphere, and lithosphere?
A: The coolest layers are farthest from the core.
B: The least dense layers are closest to the core.
C: The layers with the highest concentration of metals are closest to the crust.
D: The layers that remain in a molten state are closest to the crust.
Answer:
The coolest layers are farthest from the core.
Explanation:
When we talk about the internal structure of Earth, we mean the subdivisions of the solid Earth, that is, the concentric spherical layers that marks out the structure of the solid Earth.
The inner core is the innermost part of the earth's core and is known to have extremely high temperature. This high temperature steadily decreases as you approach the earth's surface.
Hence, the coolest layers are farthest from the core.

calculate the volume occupied by 10g of propane gas, under normal conditions of temperature and pressure
Answer:
5.5 L
Explanation:
First we convert 10 g of propane gas (C₃H₈) to moles, using its molar mass:
10 g ÷ 44 g/mol = 0.23 molThen we use the PV=nRT formula, where:
P = 1 atm & T = 293 K (This are normal conditions of T and P)n = 0.23 molR = 0.082 atm·L·mol⁻¹·K⁻¹V = ?1 atm * V = 0.23 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 293 K

Answer:
A glass of mineral water is not pure water.
Explanation:
Pure chemical substances
Pouring water into a glass from a bottle
Food and drink may be advertised as ‘pure’. For example, you may see cartons of ‘pure orange juice’ or ‘pure mineral water’. This means that nothing else was added to the orange juice or mineral water during manufacture. However, these substances are not pure to a scientist. In science, a pure substance contains only one element or compound.
Mineral water is mostly water, but there are other substances mixed with it. These are the ingredients that you see listed on the bottle’s label.
how many atoms of alumminum are in 3.9 mol of aluminum
Answer:
2.35 x 10²⁴ atoms Al
Explanation:
Given 3.9 moles of aluminum (Al), determine number of aluminum atoms in that quantity of substance.
By definition a mole is the mass of substance containing one Avogadro's Number (N₀) of particles. That is, 1 mole = 1 N₀ = 6.023 x 10²³ particles*.
So, if 1 mole aluminum contains 6.023 x 10²³ atoms of aluminum then
3.9 moles Al = 3.9 moles Al x 6.023 x 10²³ atoms Al/mole Al = 2.35 x 10²⁴ atoms Al.
________________
*The complete equivalent relationship is ...
1 mole (atoms or compounds) = 6.023 x 10²³ atoms or molecules = 1 formula weight of the substance = 22.4 Liters (if in gas phase at STP conditions (0°C and 1atm pressure).

Answer:
A meteor shower are defined as the celestial event in which a meteor comes from one point in the sky and visible in night sky.
Meteors are also known as Shooting stars as they glow when enters in the Earth surface as glowing streaks, where tail point to the origin in the sky and face faces the Earth surface.

C1V1=C2V2
C1 is 2.0mol/l
V1=?
C2=.4mol/L
V2=100ml or for this 0.1L

if you need 2.5 moles of of aluminum, how many atoms of aluminum is this?
Answer:
This can be found by my multiplying number of moles with avogadro number
So we have:
2.5 × 6.022 × 10²³
= 15.055 × 10²³
Therefore there are 15.055 × 10²³ atoms in 2.5 moles of Aluminium
What is the difference between a chemical symbol and a chemical formula?
Answer: A chemical symbol is a one- or two-letter designation of an element. Compounds are combinations of two or more elements. A chemical formula is an expression that shows the elements in a compound and the relative proportions of those elements. Many elements have symbols that derive from the Latin name for the element
Are physical characteristics of an organism not genetically passed down?
In an ecosystem, the physical characteristics of an organism are genetically passed down from one generation to another.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

A gas has a volume of 500cm3 when a pressure of 100,00N is exacted on it what will be it's volume if the pressure is changed to 150mm mecury at same temperature
Answer:
See explanation below
Explanation:
At first sight, it seems that the innitial pressure of 100,00 N would be 100,00 N/m² because pressure does not have units of newton alone. If this is true, then the calculations are the following (If it's not, but it's actually mm Hg, then skip the part of the conversion, and just do the procedure of solving for the volume).
The innitial pressure is 100 N/m² or simply 100 Pa. As the second pressure is in mm Hg, let's convert the Pascal units to mm Hg:
1 Pa -----> 0.007501 mm Hg
100 ---------> X
X = 100 * 0.007501 / 1 = 0.7501 mmHg
Now that we have the innitial pressure in mm Hg, and the temperature remains constant, we use the Boyle's law to solve for this:
P₁V₁ = P₂V₂
V₂ = P₁V₁ / P₂
Using this expression, let's solve for V₂:
V₂ = 0.7501 *¨500 / 150
V₂ = 2.5 cm³
Now, it's the innitial pressure is 100 mm Hg then the volume:
V₂ = 100 * 500 / 150
V₂ = 333.33 cm³
Check the units of the innitial pressure, one of these results should be the correct answer. If it's not, then please post again the question with the correct units.
