Explain the physical and chemical properties of water, including its different phase changes. Why is water so critical for human life?

Submission

Answers

Answer 1
The physical properties of water is that it is clear, it has no taste. No odour. It freezes at 0 degrees Celsius and boils at 100 degrees Celsius. The different stages of water is liquid, solid and gas. It is liquid at normal state. Ice when solid and steam when it is a gas state.

It is essential for human life because majority of the human body is made out of water. The water in the body allows certain parts and organs to function properly. Without water humans are most like to become I’ll and even dehydrate causing major injuries. It is also essential for the brain to function

Which of the following liquids has the highest viscosity
A water
B oil
C milk
D honey

Answers

Answer:

honey has the highest viscosity

According to the given option, honey is the liquid that has the highest viscosity. So, the correct option is D.

What do you mean by Viscosity?

Viscosity may be defined as the effects of a liquid by probity of which an internal resistance comes into play when the liquid is in movement and resists the comparable motion between its distinct layers.

Among all the given options, honey possesses more strong intermolecular attractive forces that result in the high compaction of particles in the honey.

After honey, Oil is more viscous followed by milk, and then water.

Therefore, the correct option for this question is D.

The ribosome of plant cells are sites for the synthesis of proteins. The correct option is (d).

What are ribosomes?

Ribosomes are organelles that take part in the synthesis of proteins. The prokaryotic cell's ribosomes are smaller than the eukaryotic cell's ribosomes.

Currently, ribosomal RNA is a component of the cell's ribosome or protein-building machinery. The process of making proteins, or translation, is carried out by ribosomes.

The ribosome, which translates the genetic code generated in mRNA into an amino acid sequence, is universally responsible for protein synthesis. The two ribosomal subunits, small and big, come together to form the full ribosome, which is used to produce proteins.

Therefore, the correct option is (d) proteins.

In one to two sentences, describe an experiment that would show that intramolecular forces (attractions between atoms within molecules) are stronger than intermolecular forces (attractions between molecules).

Answers

Answer:

If the molecules have similar molar masses and similar types of intermolecular forces, look for the one that is the most polar or that has the most electronegative atoms or the most hydrogen bonding groups. That one will have the strongest IMF's overall.

Explanation:

An experiment that would show that intramolecular forces are stronger than intermolecular forces will be heating a block of ice in a sealed container then allowing it to change to steam.

Intramolecular forces are the forces of attraction that hold atoms together within a molecule. Intramolecular forces require a high amount of energy to splits atoms or molecules in a chemical bonding.

Intermolecular forces are weaker forces of attraction that occur between molecules. They require lesser energy to splits molecules compared to intramolecular forces.

An experiment that show that intramolecular forces are stronger than intermolecular forces will be heating a block of ice in a sealed container then allowing it to change to steam.

In the process, the energy required to change the state from ice to steam water is more than intermolecular forces.

Thus, we can conclude that this experiment shows that the intramolecular forces are stronger than the intermolecular forces.

how would you expect the solubility of barium sulfate in pure water to compare to its solubility in 0.10 m nacl

Answers

Answer:

barium sulfate is insoluble (unable to dissolve) in water.

the general equation for the reaction between solid barium sulfate and nacl solution is this:

BaSO4 (s) + 2NaCl (aq) --> BaCl (aq) + Na2SO4 (aq)

to sum this up, to compare the solubility,

1. barium sulfate cant dissolve in pure water.

2. barium sulfate dissolves in nacl solution to give aqueous (aq) barium chloride (bacl) and aqueous sodium sulfate (na2so4), as shown in the equation above.

good luck!

The solubility of barium sulfate in pure water to zero as compare to the solubility in NaCl solution.

What is solubility?

Solubility is a property of any substance that defines how easily can be any substance will get dissolved or show dissolution.

Barium sulphate is insoluble in water beacuse it has higher lattice energy as well as higher size of cations & anions as compare to water, due to which water is not able to attract these ions towards itself affectively.Barium sulphate is soluble in the NaCl solution as this solution having ions which have more power to attract the ions of barium sulphate and show dissolution. Chemical reaction for this will be represented as:

         BaSO₄ (s) + 2NaCl (aq) → BaCl (aq) + Na₂SO₄ (aq)

Hence, barium sulphate is insoluble in water.

Explanation:

If the energy of the H–H bond is 452 kJ/mol. The energy of the O=O bond is 598 kJ/mol. The energy of the O–H bond is 367 kJ/mol, which bond would be the strongest? Which bond would be the weakest?

Answers

Taking into account the bond energy, the O=O bond is the strongest and the O–H bond is the weakest.

The bond energy is the average total energy that would be released by the formation of a mole of chemical bonds, from their constituent fragments (all in the gaseous state).

In other words, the normal or standard bond enthalpy is defined as the change in enthalpy or heat released, under standard conditions of 1 atmosphere and 25ºC, that accompanies the reaction of formation of one mole of bonds from the isolated atoms in gaseous state.

The higher the bond energy, the stronger and more stable the bond will be.

So, taking into account all the previous, the O=O bond is the strongest and the O–H bond is the weakest.
