Solubility has been the property of the substance to get dissolved to form the solution. Methanol (CH₃OH) is more soluble in water than Diiodomethane (CH₂I₂).
What is solubility?Solubility is best defined as the capability of the substance to get dissolved or dissociated into a solvent for the formation of the solution at a given temperature. The solubility of the various substances varies and is an important part of the mixture and solution.
Solubility in water has been the measure of the solute to get dissolved in water. The pressure and the temperature of the system directly affect the solubility of any substance in a solvent. Water is a polar molecule with hydrogen bonds in a great solvent that dissolves almost all the molecules like salt, sugar, etc.
Methanol is soluble in water as it contains hydrogen bonds as the intermolecular forces that interact with the polar water molecule by the virtue of the hydroxide and the hydrogen ions that show the molecular attraction and allows the molecule to get dissolved.
Therefore, methanol is soluble in water.

A sample of ammonia, NH3, has a mass of 78.25 g. Calculate the number of ammonia molecules in the sample.
number of molecules:
Answers
There are approximately \(2.76 * 10^{24\) ammonia molecules in the given sample.
To calculate the number of ammonia molecules in the sample, we need to use Avogadro's number and the molar mass of ammonia.
The molar mass of ammonia \((NH_3)\) can be calculated by adding up the atomic masses of nitrogen (N) and hydrogen (H):
Molar mass of \(NH_3\) = (1 x atomic mass of N) + (3 x atomic mass of H)
= (1 x 14.01 g/mol) + (3 x 1.01 g/mol)
= 14.01 g/mol + 3.03 g/mol
= 17.04 g/mol
Now, we can calculate the number of moles of ammonia in the sample using the formula:
Number of moles = Mass of the sample / Molar mass
Number of moles = 78.25 g / 17.04 g/mol
≈ 4.5865 mol (rounded to four decimal places)
Finally, we can use Avogadro's number, which represents the number of particles (atoms, molecules, etc.) in one mole of a substance. Avogadro's number is approximately \(6.022 * 10^{23\) particles/mol.
Number of ammonia molecules = Number of moles x Avogadro's number
Number of ammonia molecules ≈ 4.5865 mol x (\(6.022 * 10^{23\) molecules/mol)
≈ \(2.76 * 10^{24\) molecules (rounded to two significant figures)
Therefore, the provided sample contains roughly \(2.76 * 10^{24\) ammonia molecules.

The number of ammonia molecules in the sample is approximately 2.764 x \(10^{24}\) molecules.
To calculate the number of ammonia molecules in a given sample, we need to use Avogadro's number and the molar mass of ammonia.
The molar mass of ammonia (NH3) is calculated as follows:
Molar mass of N = 14.01 g/mol
Molar mass of H = 1.01 g/mol
Total molar mass of NH3 = 14.01 g/mol + (3 * 1.01 g/mol) = 17.03 g/mol
Now, we can calculate the number of moles of ammonia in the sample:
Number of moles = Mass of sample / Molar mass of NH3
Number of moles = 78.25 g / 17.03 g/mol = 4.594 moles
Next, we use Avogadro's number, which states that there are 6.022 x \(10^{23}\) molecules in one mole of a substance.
Number of molecules = Number of moles * Avogadro's number
Number of molecules = 4.594 moles * 6.022 x \(10^{23}\) molecules/mol = 2.764 x \(10^{24}\) molecules
Therefore, there are approximately 2.764 x \(10^{24}\) ammonia molecules in the given sample of 78.25 g.

How many mg of water are present in a 500. mg sample of 2.9 m/m% solution?
Report your answer to 3 significant figures and without units.
Answers
The answer is 14.5 mg.
To solve the problem, we need to first understand what a 2.9 m/m% solution means. "m/m%" stands for mass per mass percentage, which indicates the mass of the solute (in this case, water) divided by the total mass of the solution (water + solvent, which is not specified). Therefore, a 2.9 m/m% solution means that for every 100 grams of the solution, 2.9 grams are water.
To find the amount of water present in a 500 mg sample of this solution, we can set up a proportion:
2.9 g water/100 g solution = x g water/500 mg solution
Simplifying this proportion by converting units to milligrams, we get:
2.9 mg water/100 mg solution = x mg water/500 mg solution
Cross-multiplying and solving for x, we get:
x = 14.5 mg
Therefore, there are 14.5 mg of water present in a 500 mg sample of 2.9 m/m% solution.

Another way you could collect or determine the pressure data without using a gas pressure sensor involving the same chemical reaction is using the Ideal Gas Equation.
A gas pressure sensor is a device used to monitor and collect data on the pressure changes and variations in a gas participating in a chemical reaction.
In a chemical reaction, the Ideal Gas Equation can be used to determine the pressure data without using a gas pressure sensor if the variables are known.
For example;
the numbers of moles(n) participating in the reaction, the volume(V), and;the temperature(T) at which the reaction is being carried outThe Ideal gas equation can be represented as:
PV = nRTwhere;
P = pressure data of the gasV = volume of the gasn = number of molesR = gas rate constantT = temperature of the gas.Therefore, we can conclude that the Ideal Gas Equation can be used to determine the pressure data without using a gas pressure sensor if the variables are known.

Answers
Answer:
The Answer will be provided below, please pay attention in class next time so that you don't have to be in a hurry like you are in now.
Explanation: The correct option is:
Both fossil fuels and wind energy can be used to produce electricity. However, burning fossil fuels does pollute the atmosphere, while using Earth's wind does not. Both fossil fuels and wind energy contribute to climate change, but the use of fossil fuels is much more damaging to the environment than the use of wind power.
Fossil fuels are non-renewable sources of energy that are formed over millions of years by the decomposition of organic matter. They release harmful greenhouse gases when burned, contributing to climate change. In contrast, wind energy is a renewable source of energy that uses turbines to harvest the power of wind. Wind energy does not produce any emissions, making it an environmentally friendly alternative to fossil fuels. While wind turbines can have some impacts on wildlife and habitats, the impact is much less severe than the effects of fossil fuel extraction and burning.
Added Part: Fossil fuels are non-renewable sources of energy that are derived from the remains of plants and animals that died millions of years ago. These sources include coal, oil, and natural gas. Wind energy, on the other hand, is a renewable source of energy that is generated by the kinetic energy of wind.
Here are some comparisons between fossil fuels and wind energy:
Environmental Impact: Fossil fuels have a significant negative impact on the environment. Burning fossil fuels produces greenhouse gases that contribute to climate change. The extraction of fossil fuels also has negative impacts on the air, water, and soil. Wind energy, however, has a very small environmental footprint. Wind turbines do not produce any emissions and do not require any water to generate electricity.
Energy Availability: Fossil fuels are abundant and have been the primary source of energy for decades. On the other hand, wind energy is a relatively new source of energy and the technology is still developing. However, the availability of wind energy is significant, as wind is a renewable source that is constantly available.
Sustainability: Fossil fuels are non-renewable, which means they will eventually run out. As the demand for energy continues to increase, the availability of fossil fuels will decrease. Wind energy is a renewable source of energy that will never run out.
Here are some pros and cons of both fossil fuels and wind energy:
Fossil Fuels:
Pros:
Reliable source of energy
High energy density
Large global infrastructure
Cons:
Non-renewable source of energy
Significant environmental impact
Price instability
Wind Energy:
Pros:
Renewable source of energy
Small environmental footprint
Low operating costs
Cons:
High initial costs for building wind turbines
Wind is an inconsistent source of energy

A 25.00 gram sample of an unknown metal initially at 99.0 degrees Celsius is added to 50.00 grams of water initially at 14.33 degrees Celsius. The final temperature of the system is 20.15 degrees Celsius. Calculate the specific heat of the metal. (The specific heat of water is 4.184 J/g*C). Record your answer in scientific notation using three significant figures.
Answers
The specific heat of the metal can be calculated using calorimetric equation. The specific heat of the metal here is 0.61 J/g °C.
What is specific heat capacity?The specific heat capacity of substance is the heat energy required to raise its temperature by one degree Celsius per one gram of the substance.
The calorimetric equation connecting the heat energy q, mass m, specific heat c and temperature difference ΔT is:
q = m c ΔT
Here, the heat released from the metal is equal to the heat absorbed by water.
Therefore,
q metal = q water. Let c be the specific heat of the metal.
25 g × ( 99 - 20.15°C) ×c = 50 g × ( 20.15°C- 14.33) × 4.18 J/g °C
= 1217.5 J
Then c = 1217.5 J/25 g × ( 99 - 20.15°C) = 0.61 J/g °C.
Therefore, the specific heat of the metal is 0.61 J/g °C.

The sodium hydroxide solution has a molarity of 0.0863 M.
How can the molarity of standardised NaOH be determined?Divide the number of moles of NaOH by the number of litres of NaOH solution needed to reach the titration's endpoint to determine the molarity of the NaOH solution.
KHP + NaOH → NaKP + H2O
moles NaOH = (volume of NaOH solution used in liters) x (molarity of NaOH solution)
moles NaOH = 35.01 mL x (1 L/1000 mL) x (Molarity of NaOH)
moles KHP = (mass of KHP) / (molar mass of KHP)
