Answers
The molecule that will likely dissolve in water is H OH (hydroxyl group), which is present in carbohydrates, proteins, and nucleic acids.
Polar bonds are covalent bonds where there is a separation of electric charge, and this difference arises from differences in the electronegativity of the atoms forming the bond. The electronegativity is defined as the ability of an atom to attract electrons towards itself in a covalent bond. The molecule's polarity determines its solubility in water.
For example, polar molecules are generally more soluble in water than nonpolar molecules. Water molecules have a positive end and a negative end, and they are attracted to the polar regions of a molecule. Organic molecules are molecules that contain carbon atoms. The four classes of organic molecules are carbohydrates, lipids, proteins, and nucleic acids.
The molecule that will likely dissolve in water is H OH (hydroxyl group), which is present in carbohydrates, proteins, and nucleic acids. Hydroxyl groups are polar and can form hydrogen bonds with water molecules. Polar bonds are responsible for water solubility.
In conclusion, polar molecules dissolve in water because they have the same or similar properties to water. They have a polarity that allows them to interact with water molecules, which makes them dissolve in water. The molecule with the hydroxyl group is likely to dissolve in water.

When 0. 105 mol propane, c3h8 is burned in an excess of oxygen, how many moles of oxygen are consumed? the products are carbon dioxide and water. You have to properly balance the equation before you can answer this question.
Answers
Therefore, 0.525 moles of oxygen are required to react with 0.105 moles of propane.
The balanced equation for the combustion of propane is:
C3H8 + 5O2 -> 3CO2 + 4H2O
From this equation, we can see that 1 mole of propane reacts with 5 moles of oxygen to produce 3 moles of carbon dioxide and 4 moles of water.
Since we have 0.105 mol of propane, we need to determine how many moles of oxygen are required to react with it. Using the mole ratio from the balanced equation, we can set up a proportion:
0.105 mol C3H8 / 1 x (5 mol O2 / 1 mol C3H8) = 0.525 mol O2

List all possible values of the angular momentum quantum number l for an electron in the L(n=2) shell of an atom.
Answers
In quantum mechanics, the angular momentum quantum number "l" defines the shape of the atomic orbital. The l value is an integer ranging from 0 to (n-1) where n is the principal quantum number.
Therefore, for an electron in the L(n=2) shell of an atom, the possible values of the angular momentum quantum number l would range from 0 to 1, since n=2.
This is because the L shell is the second shell, which has n=2. Therefore, it can have subshells with l=0 and l=1, also known as the s and p subshells respectively.
The angular momentum quantum number also has an effect on the energy of the electron, with higher l values having higher energy.
Thus, the possible values of the angular momentum quantum number l for an electron in the L(n=2) shell of an atom are l=0 and l=1.

Calculate the mass of the reaction mixture in each reaction. (To do this, first determine the total volume of the solution. Then calculate the mass of the solution, based on the assumption that the added solid does not change the volume and that the density of the solution is the same as that of pure water, 1.0 g/mL.) Remember to add the mass of the solid.
Answers
The mass of the solution will be equal to the total volume of the solution in mL multiplied by the density of the solution in g/mL.
To calculate the mass of the reaction mixture in each reaction, we first need to determine the total volume of the solution. This can be done by adding the volumes of the individual components of the solution.
Once we have the total volume, we can calculate the mass of the solution by assuming that the density of the solution is the same as that of pure water, which is 1.0 g/mL.
Next, we need to add the mass of the solid to the mass of the solution to get the mass of the reaction mixture. The mass of the solid can be determined by weighing it on a balance before adding it to the solution.
Therefore, the mass of the reaction mixture can be calculated using the following formula:
Mass of reaction mixture = (Total volume of solution x Density of solution) + Mass of solid
= (Total volume of solution x 1.0 g/mL) + Mass of solid
= Mass of solution + Mass of solid
By plugging in the values for the total volume of the solution and the mass of the solid, we can calculate the mass of the reaction mixture for each reaction.

The measurement 45 N represent the magnitude (size) of a force in photograph. Therefore, option C is correct.
What is the magnitude of a force?The magnitude of the force is the number that represents the force's strength. Assume the force is 10 N in the direction of the east. The direction is indicated by 'towards east,' and the magnitude is indicated by '10'. Magnitude is thus the 'value' or 'amount' of any physical quantity.
The magnitude of force is expressed in mass times length times time squared. The most common metric unit is the newton (N), which is defined as one kilogram times one meter over one second squared.

Pentene, C5H10 (molar mass = 70.15 g/mol) has a heat of vaporization of 29.82 KJ/mol. How many moles of pentene, at its boiling point, can be vaporized with the addition of 88 J of energy? (Round your answer to the correct number of significant figures.)
Answers
The amount of energy required to evaporate a given number of moles of pentene is given by the formula:
ΔHvap = energy/mole Rearranging the formula gives:
Mol = Energy/ΔHvap Substituting the given values, we get:
mol = (88 J) / (29.82 kJ/mol) = 0.0029488 mol Rounding to the correct number of significant digits gives:
Moles = 0.003 Moles
Thus, 0.003 moles of pentene can be evaporated while supplying 88 J of energy.
What is evaporation?
When a liquid becomes a gas, this process is called evaporation. If you boil water in a pot, you can observe the evaporation. Evaporation is done in two ways:evaporation and boiling.

how many gr of MGSO4 do we get from the reaction of 2 moles MGO with H2SO4?
Answers
We can produce 240.74 g of Magnesium sulfate from the reaction of 2 moles of Magnesium oxide with Sulfuric acid.
How can you figure out how many grammes a reaction produces?As a result, we can see that we may obtain moles of our initial reactant by dividing its original mass in grammes by its molar mass. To obtain moles of product, multiply those grammes by the products-to-reactants ratio, which is 2:4. Lastly, we multiply the product's moles by its molar mass to obtain its grammes.
Magnesium oxide + Sulfuric acid → Magnesium sulfate + Water
The molar mass of Magnesium sulfate is:
Magnesium sulfate = 24.31 + 32.06 + (4 x 16.00) = 120.37 g/mol
So, 2 moles of Magnesium sulfate would have a mass of:
mass = 2 moles x 120.37 g/mol = 240.74 g
