How do the properties of oxygen and hydrogen compare with the Properties of the water?
Oxygen and hydrogen are gases at room temperature, while water is a liquid. In its gaseous form, oxygen is colorless and odorless, hydrogen is colorless and highly flammable. Water is a polar molecule with a bent shape, while oxygen and hydrogen are diatomic molecules.
How does the size of a carbon molecule compare to that of hydrogen?
A carbon atom is about 1.5 times as big as a hydrogen atom.You'd need to be more specific about what you mean by "a carbon molecule". Carbon molecules can be enormous.
How does the explosiveness of hydrogen compare to that of gasoline?
Hydrogen is more explosive than gasoline.
Why does hydrogen fluoride have a higher boiling point than hydrogen chloride?
The small size and high electronegativity of Fluorine is responsible for high polarity in HF molecules this high polarity is responsible for strong hydrogen bonding with in HF molecules so high amount of heat is required to convert the liquid HF into gaseous state and hence it has high boiling point as compare to HCl.Polar.
Why hydrogen gas is not liberated when metals react with nitric acid?
Nitric acid is a strong oxidizing agent that can oxidize hydrogen gas to water instead of being reduced itself to release hydrogen gas. As a result, metals do not liberate hydrogen gas when they react with nitric acid.

How does the ratio compare with hydrogen and oxgen atoms ratio in carbohydrates?
The ratio of hydrogen to oxygen in carbohydrates is 2H:1O, which is the same ratio as in water molecules.

How do hydrogen bounds compare with other intermolecular forces?
Hydrogen bonds are much stronger than other intermolecular forces.
How do two water molecules compare to two magnets?
Two water molecules are held together by hydrogen bonds, while two magnets are held together by magnetic forces between their poles. Water molecules can form a liquid state due to hydrogen bonding, while magnets do not exhibit this behavior due to their magnetic properties. Additionally, the interaction between two water molecules is based on polarity, while the interaction between two magnets is based on the alignment of their magnetic fields.
Why does isopropanol boil higher temperature than acetone?
Because isopropanol, as an alcohol, has hydrogen bonding between its alcohol hydrogens and oxygens, increasing intermolecular forces and thus increasing boiling point. Acetone, a ketone, has very little hydrogen bonding because its hydrogens don't have electron density taken away from them since they're not attached to oxygen (in other words, they're not acidic).
Is Hydrophobic interactions are stronger than hydrogen bond?
Hydrophobic interactions are repulsive and hydrogen bonds are attractive forces. So, not sure hydrophobic interaction is classified as a "force" but rather and "interaction". Hydrogen bonds are relatively strong forces. It's really difficult to compare hydrophobic interaction with hydrogen bond because they are sort of opposite.
In a hydrogen peroxide and yeast experiment what is the purpose of the cups with yeast and nothing?
The cups with yeast and nothing serve as a control in the experiment to compare the rate of reaction when hydrogen peroxide is added. By observing how the control cup behaves without the hydrogen peroxide, we can compare any changes in the cups with yeast and hydrogen peroxide to see the effect of the reaction.
How do the melting points of covalent molecules and ionic compounds compare?
Covalent molecules generally have lower melting points than ionic compounds because the intermolecular forces between covalent molecules are weaker than the electrostatic forces between ions in ionic compounds. This is because covalent molecules are held together by dispersion forces, dipole-dipole interactions, and hydrogen bonding, which are weaker compared to the strong ionic bonds present in ionic compounds.
