The organic compound with ionized functional groups would be most soluble in a polar solvent. The best choice among the given solvents is d. water.
Water is a highly polar solvent due to the presence of hydrogen bonding. Compounds with ionized functional groups are typically polar or ionic, and they will dissolve well in polar solvents like water. This is because the polar solvent can stabilize and interact with the charged functional groups, allowing the compound to dissolve effectively. Other solvents in the list, such as 2-propanone (acetone), cyclohexane, cyclohexanol, and 2-propanol (isopropyl alcohol), may have varying degrees of polarity, but water is the most polar and would be the best choice for dissolving a compound with ionized functional groups.

Given a 6.80 g sample of H2O how many grams of oxygen is produced assuming the decomposition goes to completion
Answer:
6.0444g
the formula must be after balancingknown as 36(mass) of H2O can produce 32(mass) of O2so 6.80g of H2O can produce (x)g of oxygenAccording to the stoichiometry of the decomposition of water 6.04 grams of oxygen is produced assuming the decomposition goes to completion.
What is stoichiometry?Stoichiometry is defined as the determination of proportions of elements or compounds which are present in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.
Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.It is useful in balancing chemical equations.According to the reaction, 36 g water gives 32 g oxygen thus 6.80 g water will give 6.80×32/36=6.04 g.
Thus, on decomposition of water 6.04 grams of oxygen is produced assuming the decomposition goes to completion.

Find the amount of water containing 14.02 * 10²⁴ molecules
Answer:
14.02 x 10²⁴ molecules
Explanation:
To solve this problem we will use Avogadro's number: It relates to the number of molecules (or atoms) contained in 1 mol of any given substance:
14.02 x 10²⁴ molecules ÷ 6.023 x 10²³ molecules/mol = 23.28 molesThus, 23.28 moles of water contain 14.02 x 10²⁴ molecules.

industrial gases cause acid rain why
because the industrial gas is very harmful for us it is made up chemical and toxic gases
Answer:
The usual culprit is burning coal.
Explanation:
This produces a lot of carbon dioxide as well as sulphur dioxide. Other industrial processes, and vehicle emissions, produce similar oxides unless they are 'scrubbed' out. They react with atmospheric moisture to produce acids like carbonic, sulphurous and nitrous acids. Which is then precipitated. It should be remembered that a volcanic eruption has this effect too.

Can someone help me with my stoichiometry homework, it is due tonight.
Answer:
1. 1 mole of NaCl.
2. 1 mole of H₂O.
Explanation:
The balanced equation for the reaction is given below:
HCl + NaOH —> NaCl + H₂O
From the balanced equation above,
1 mole of HCl reacted with 1 mole of NaOH to produce 1 mole of NaCl and 1 mole of H₂O.
Next, we shall determine the limiting reactant. This can be obtained as follow:
From the balanced equation above, we can see that 1 mole of HCl reacted completely with 1 mole of NaOH. Therefore, HCl is the limiting reactant and NaOH is the excess reactant since we have 3.6 moles of NaOH.
1. Determination of the amount of NaCl produced from the reaction.
NOTE: The limiting reactant is used to determine the maximum amount produced since all of it is consumed in the reaction.
The limiting reactant is HCl and the amount of NaCl produced can be obtained as follow:
From the balanced equation above, we can see that 1 mole of HCl reacted to 1 mole of NaCl.
Thus, 1 mole of NaCl was produced.
2. Determination of the amount of H₂O produced from the reaction.
From the balanced equation above, it is evident that 1 mole of HCl reacted to produce 1 mole of H₂O.
Thus, 1 mole of H₂O was produced.

Which statement about copper, diamond, and silicon(IV) dioxide is correcta)Copper and silicon(IV) dioxide have similar electrical conductivityb)In diamond the carbon atoms are covalently bonded as flat sheetsc)In silicon(IV)dioxide the silicon and oxygen atoms are covalently bonded in flat sheetsd)The structure of copper includes a lattice of positive ions
Answer:
In diamond the carbon atoms are covalently bonded as flat sheets
In silicon(IV) dioxide the silicon and oxygen atoms are covalently bonded in flat sheets
The structure of copper includes a lattice of positive ions
Explanation:
Diamond and silicon(IV) dioxide are covalent network solids. Covalent network solids are made up of atoms joined to one another by covalent bonds to form a giant lattice, The solids are hard and have a very high melting point. They do not conduct electricity. So, for both diamond and SiO2, atoms are covalently bonded to yield flat sheets in a covalent bonded network solid.
Copper is a metallic substance having metallic bonds, a metallic crystal consists of positive ions and a cloud of electrons.
What is the difference between an empirical formula and a molecular formula?
Answer:
The empirical formula simply states the ratios of the elements that make up the molecule, while molecular formulas specify the amounts of each element exactly, not just giving the ratio. Let's take ethane (C2H6) as an example.
Why do you think males and children are more likely to die from DHMO
Answer:
Dihydrogen Monoxide (DHMO) is perhaps the single most prevalent of all chemicals that can be dangerous to human life. Despite this truth, most people are not unduly concerned about the dangers of Dihydrogen Monoxide. Governments, civic leaders, corporations, military organizations, and citizens in every walk of life seem to either be ignorant of or shrug off the truth about Dihydrogen Monoxide as not being applicable to them. In 1997, the Dihydrogen Monoxide Research Division was formed and went online spreading the truth about DIHYDROGEN MONOXIDE. As word has spread, so too has the public awareness of Dihydrogen Monoxide and its implications involving the Internet and accessibility of such information. To that end, the DMRD's web site at DHMO.org continues to provide the most comprehensive collection of Dihydrogen Monoxide information available anywhere.
Explanation:
DHMO has been the dihydrogen monoxide. It has been responsible for the death of males and children as it causes tissue damage.
The DHMO has been the hydric acid and is one of the major constituents of acid rain. Gas has been responsible for greenhouse gas. Ingestion may lead to tissue damage with symptoms of nausea, vomiting, and electrolyte imbalance.
The companies dumping waste in the rivers and lakes have been warned for the removal of DHMO as it has been harmful to the males and children, and results in death.

What is the freezing point of a solution of 498mL of water (solute) dissolved in 2.50 L of ethanol (solvent), C2H5OH? The density of C2H5OH is 0.789g/cm3. (Remember that water has a density of 1.0 g/cm3.)
Answer:
Freezing T° of solution is -142.4°C
Explanation:
This excersise is about colligative properties, in this case freezing point depression,
ΔT = Kf . m . i
Where ΔT = Freezing T° of solvent - Freezing T° of solution
Kf = Cryoscopic constant
m = mol/kg (molality)
i = Number of ions dissolved.
Water is not ionic, so i = 1
Let's find out m.
We determine mass of water, by density
498ml . 1 g/mL = 498 g
We convert the mass of water to moles → 498 g . 1mol/18g = 27.6 moles
We determine mass of solvent by density
2500 mL . 0.789 g/mL = 1972.5 g
Notice, we had to convert L to mL to cancel units.
1 cm³ = 1 mL
We convert the mass from g to kg → 1972.5 g . 1kg /1000g = 1.97kg
We determine m = mol/kg → 27.6mol / 1.97kg = 13.9 m
Kf for ethanol is: 1.99 °C/m
Freezing T° for ethanol is: -114.6°C
We replace at formula: - 114.6°C - Freezing T° solution = 1.99 °C/m . 13.9 m . 1
- 114.6°C - Freezing T° solution = 27.8 °C
- Freezing T° solution = 27.8°C + 114.6°C
Freezing T° Solution = - 142.4 °C
