Isopropanol spread on a table will form a layer that evaporates quickly and may cool the surface or damage materials sensitive to alcohol. It is also flammable, creating a fire risk near open flames or heat sources.
When isopropanol is poured out of its container onto a table, it behaves similarly to how water or other liquids would behave. Due to its low viscosity, isopropanol will spread out across the table's surface, forming a thin layer.
Since isopropanol evaporates much faster than water at room temperature, it would begin to evaporate quickly, leaving behind a cool sensation due to the evaporation process removing heat from the surroundings. If the table is made of a material that can be degraded by alcohol, such as certain plastics or finishes, the isopropanol may also cause damage to the table's surface.
Furthermore, it's important to note that isopropanol is flammable, so if it is poured near an open flame or a heat source, there is a risk of ignition. Therefore, handling isopropanol should be done with caution, and proper ventilation should be ensured to prevent the build-up of flammable vapors.

What is the solubility in mol/L of copper(I) sulfide, Cu2S? Its Ksp value is 6.1 × 10-49 .
Answer:
5.3 × 10⁻¹⁷ mol·L⁻¹
Explanation:
Let s = the molar solubility.
Cu₂S(s) ⇌ 2Cu⁺(aq) + S²⁻(aq); K_{sp} = 6.1 × 10⁻⁴⁹
E/mol·L⁻¹: 2s s
K_{sp} =[Cu⁺]²[S²⁻] = (2s)²×s = 4s^3 = 6.1 × 10⁻⁴⁹
[tex]s^{3}= \frac{6.1 \times 10^{-49}}{4} = 1.52 \times 10^{-49}[/tex]
[tex]s = \sqrt[3]{1.52 \times 10^{-49}} \text{ mol/L} = 5.3 \times 10^{-17} \text{ mol/L}[/tex]
The solubility of copper(I) sulfide, Cu2S, in water, given its Ksp value of 6.1 × 10^-49, is calculated to be approximately 1.15 × 10^-17 mol/L. by understanding the dissolution process and solving the Ksp expression.
The question asks about the solubility of copper(I) sulfide, Cu2S, given its Ksp value is 6.1 × 10^-49. To solve for the solubility in mol/L, we must first understand the dissolution process of Cu2S in water. The equation for this process is Cu2S(s) → 2 Cu+(aq) + S2-(aq). For every mole of Cu2S that dissolves, it produces 2 moles of Cu+ and 1 mole of S2-. Therefore, if the solubility of Cu2S is 's' mol/L, the concentration of Cu+ ions is 2s mol/L, and the concentration of S2- ions is s mol/L.
Substituting these values into the Ksp expression gives: Ksp = [2s]^2[s] = 4s^3. Plugging in the Ksp value of 6.1 × 10^-49 and solving for 's' provides: 4s^3 = 6.1 × 10^-49, leading to s^3 = 1.525 × 10^-49 and s ≈ 1.15 × 10^-17 mol/L. Therefore, the solubility of copper(I) sulfide, Cu2S, in water is approximately 1.15 × 10^-17 mol/L.

The question:A new grill has a mass of 30.0 kg. You put 2.0 kg of charcoal in the grill. You burn all the charcoal and the grill has a mass of 30.0 kg. What is the mass in kg of the gases given off? (assume that the charcoal is pure carbon solid and that it burns completely in oxygen).
The answer: Mass of carbon burnt = 2Kg = 2000g
Moles of Carbon burnt = 2000/12
=> Moles of CO2 produced = 2000/12
=> Mass of CO2 produced = 2000/12*44 = 2 333.33 g = 2.33 Kg
In the answer, where did the 44 come from?
Answer:- Molar mass of [tex]CO_2[/tex] .
Solution:- It is a stoichiometry problem. Mass of the grill is 30.0 kg and the mass after burning the grill is also 30.0 kg. It means all the charcol is burned and the gas is given off.
2.0 kg of charcol are converted to grams which is 2000 g. Since charcol is pure solid carbon, the grams are divided by the atomic mass of carbon which is 12.
The combustion equation of charcol is written as:
[tex]C(s)+O_2(g)\rightarrow CO_2(g)[/tex]
From this balanced equation, there is 1:1 mol ratio between charcol and carbon dioxide. So, the moles of carbon dioxide gas formed are equivalent to the moles of charcol. To convert the moles of carbon dioxide to grams we multiply the moles by it's molar mass.
Carbon dioxide has one carbon and two oxygen atoms so it's molar mass = 12 + 2(16) = 12 + 32 = 44
So, 44 is the molar mass of carbon dioxide and above calculations clearly shows how and where we get this.

After reading the latest issue of Organic Compost Quarterly, Michael, Brad and Darius have decided to investigate the effect of fish sticks on plant growth. They plan on thawing fish sticks and then aging them for various lengths of time before using them as compost to promote the growth of eggplants. Because decomposition is necessary for release of nutrients, the Alexs’ hypothesized that older fish stick compost will produce taller eggplants. Michael, Brad and Darius will grow four flats of eggplants (25 plants/flat) for 5 days.
The eggplants will then be fertilized as follows:
Flat A: 450 g of 3-month-old fish stick compost
Flat B: 450 g of 6-month-old fish stick compost
Flat C: 450 g of 12-month-old fish stick compost
Flat D: 0 g of fish stick compost

some of the alpha particles were deflected, most of the alpha particles were reflected, and a few of the alpha particles passed through the gold foil.
Answer:
b. Rutherford's experiment had the following results: a few of the alpha particles were deflected, some of the alpha particles were reflected, and most of the alpha particles passed through the gold foil.
Explanation:
Rutherford performed a series of experiments which marked an alpha particle beam on a thin gold foil and the scattering pattern was measured using a fluorescent screen. Alpha particles were detected bouncing off the gold foil in all directions, and some back at the source.
By firing alpha particles into the foils, he observe that only a small fraction of the alpha particles deflected and most flew directly through the foil.
Most rays were deflected because they pass very close to the center with an electric charge of the same type as alpha rays; very few bounced because centers of positive charge collided head-on.

Why are a molecules atoms as far away from each other as they can get
Explanation:
An atom consists of electrons, protons, and neutron. The protons and neutrons are present inside the nucleus whereas the electrons are present outside the nucleus.
These electrons revolve around the nucleus in circular motion. Therefore, an electron pair surrounds the central atom of a molecule. It is known that an electron contains a negative charge and like charges repel each other.
Hence, in an atom the force of repulsion between electron pairs pulls the atoms away from each other.
As a result, a molecules atoms are as far away from each other as they can get.

A compound is used as a food additive. The compound has a molar mass of 176.124 grams/mole. A 692.5-gram sample undergoes decomposition, producing 283.4 grams of carbon, 31.7 grams of hydrogen, and 377.4 grams of oxygen. What is the molecular formula of the compound?
A. C3H4O3
B. C4H8O4
C. C6H6O6
D. C6H8O6
E. C6H8O8
Here we have to get the correct molecular formula of the compound.
The molecular formula of the compound is C₆H₆O₆ i.e. option C.
Let assume, the empirical formula of the compound is [tex](CHO)_{n}[/tex].
The given molar mass of the compound is 176.124 g/mole.
The percent of carbon in the compound is [tex]\frac{283.4}{692.5}[/tex]×100 = 40.924.
The percent of hydrogen in the compound is [tex]\frac{31.7}{692.5}[/tex]×100 = 4.577.
The percent of oxygen in the compound is [tex]\frac{377.4}{692.5}[/tex]×100 = 54.498.
Now the ratio of the atomic number in the compound for carbon is [tex]\frac{40.924}{12}[/tex] = 3.410
Now the ratio of the atomic number in the compound for hydrogen is [tex]\frac{4.577}{1}[/tex] = 4.577
Now the ratio of the atomic number in the compound for oxygen is [tex]\frac{54.498}{16}[/tex] = 3.406
So, the C, H and O lowest ratio is [tex]\frac{3.410}{3.406}[/tex] = 1, [tex]\frac{4.577}{3.406}[/tex] = 1 and [tex]\frac{3.406}{3.406}[/tex] = 1
Thus the empirical formula of the compound is [tex][CH_{1}O] _{n}[/tex] (where n = integer.
12n + 1n + 16n = 176.24
29n = 176.24
n = 6 (approx)
Thus the molecular formula of the compound is C₆H₆O₆.
Final answer:
By calculating the number of moles of carbon, hydrogen, and oxygen and deriving the ratio among them, it is determined that the molecular formula of the compound with a molar mass of 176.124 grams/mole is C6H8O6 (D).
Explanation:
To find the molecular formula of the compound used as a food additive with a molar mass of 176.124 grams/mole from the given decomposition data, we first need to calculate the number of moles of each element present in the given sample.
For carbon: (283.4 g) / (12.0 g/mol) = 23.62 moles
For hydrogen: (31.7 g) / (1.0 g/mol) = 31.7 moles
For oxygen: (377.4 g) / (16.0 g/mol) = 23.59 moles
Next, we divide by the smallest number of moles to get the atom ratio.
C: 23.62 / 23.59 ≈ 1
H: 31.7 / 23.59 ≈ 1.34
O: 23.59 / 23.59 = 1
The ratio of hydrogen is not a whole number, so we multiply all ratios by the smallest whole number that gives us whole number ratios for each element, which in this case would be 3 (since 1.34 is approximately 4/3).
After multiplying, the moles of each element become:
C: 1 x 3 = 3
H: 1.34 x 3 ≈ 4
O: 1 x 3 = 3
Thus, the empirical formula of the compound is C3H4O3, and the molecular formula is the same as the empirical formula because the molar mass of C3H4O3 (3(12.0) + 4(1.0) + 3(16.0) = 88.0 g/mol) is half that of the given molar mass. Therefore, the molecular formula must be C6H8O6, which is twice the empirical formula.
The correct molecular formula of the compound is D. C6H8O6.

2Na + 2H2O → 2NaOH + H2 During a laboratory experiment, a certain quantity of sodium metal reacted with water to produce sodium hydroxide and hydrogen gas. What was the initial quantity of sodium metal used if 8.40 liters of H2 gas were produced at STP?
Answer : The initial quantity of sodium metal used is 17.25 grams.
Solution : Given,
Volume of [tex]H_2[/tex] gas = 8.40 L
Molar mass of Na metal = 23 g/mole
The Net balanced chemical reaction is,
[tex]2Na+2H_2O\rightarrow 2NaOH+H_2[/tex]
At STP, 22.4 L of volume is occupied by 1 mole of [tex]H_2[/tex] gas
so, 8.40 L of volume is occupied by = [tex]\frac{8.40L\times 1mole}{22.4L}[/tex] = 0.375 moles of [tex]H_2[/tex] gas
Now from the above reaction, we conclude that
1 mole of [tex]H_2[/tex] gas produced by the 2 moles of Na metal
0.375 moles of [tex]H_2[/tex] gas produced = [tex]\frac{2moles\times 0.375mole}{1mole}=0.75moles[/tex] of Na metal
The quantity of Na metal used = Moles of Na metal × Molar mass of Na metal = 0.75 moles × 23 g/mole = 17.25 grams
Therefore, the initial quantity of sodium metal used is 17.25 grams.
