The correct answer is: "B. Oxygen has a stronger attraction for electrons than hydrogen."

A water molecule is polar because it has a bent shape and an unequal sharing of electrons between the oxygen and hydrogen atoms.

Oxygen has a stronger electronegativity (ability to attract electrons) than hydrogen, which means it attracts the shared electrons in the covalent bond between the two atoms more strongly. As a result, oxygen has a partial negative charge (δ-) and hydrogen has a partial positive charge (δ+).

This separation of charges makes the water molecule polar, with a slightly negative end and a slightly positive end. This polarity allows water molecules to interact with each other through hydrogen bonding and gives water its unique properties, such as its high boiling point, surface tension, and solvent abilities.

The acceleration of the car is 2 m/s².

The average velocity of the car is 2 m/s.

The equation acceleration = (final velocity - beginning velocity) / time can be used.

Given:

Initial velocity (u) = 0 m/s (since the car starts from rest)

Final velocity (v) = 20 m/s

Time (t) = 10 s

Using the formula, we can substitute the values:

acceleration = (20 m/s - 0 m/s) / 10 s

acceleration = 20 m/s / 10 s

acceleration = 2 m/s²

Therefore, the acceleration of the car is 2 m/s².

You can use the following equation to determine the average velocity: average velocity = total displacement / total time.

The initial position and the final position are identical since the automobile begins at rest. As a result, the displacement and the ultimate position are equal.

Given:

Displacement = 20 m

Time (t) = 10 s

Using the formula, we can substitute the values:

average velocity = 20 m / 10 s

average velocity = 2 m/s

Therefore, the average velocity of the car is 2 m/s.

For an organism that has 18 chromosomes in its body cells and its sex cells have 9 chromosomes, the correct statement is C, Its sex cells are haploid and a result of meiosis.

Haploid cells have half the number of chromosomes as diploid cells. Mitosis is a type of cell division that produces two identical daughter cells. Meiosis is a type of cell division that produces four daughter cells, each with half the number of chromosomes as the parent cell.

In the organism described, the body cells are diploid (18 chromosomes) and the sex cells are haploid (9 chromosomes). This is because the sex cells are produced by meiosis, which is a type of cell division that reduces the number of chromosomes by half. This allows the sex cells to combine with each other to form a new diploid cell, which is the beginning of a new organism.

Answer: its A

Explanation: I took the test

Answer:

In this step, the conversion of sulphur dioxide to sulphur trioxide is done by mixing SO2 with atmospheric oxygen to oxidise it to form SO3 in the presence of V2O5 as a catalyst.

Answer:

The answer is a catalyst, specifically vanadium(V) oxide, V2O5.

Explanation:

A catalyst is needed for the reaction SO2-SO3. A catalyst is a substance that speeds up a chemical reaction without being consumed by the reaction. The most common catalyst used for the SO2-SO3 reaction is vanadium(V) oxide, V2O5.

The reaction SO2-SO3 is a reversible reaction. This means that the products of the reaction can react back to form the reactants. The catalyst helps to shift the equilibrium of the reaction towards the products.

The reaction SO2-SO3 is an important industrial reaction. It is used to produce sulfuric acid, which is a major industrial chemical.

The physiological process being investigated is diffusion.

The particles of the substance initially had high Kinetic Energy.​

Gas particles move quickly in all directions and regularly collide with one another and the container's side. The particles gather kinetic energy and accelerate as the temperature rises. The particles' real average speed is influenced by their mass and temperature.

In liquids, particles are quite close together and move with random motion throughout the container. Due to the closer proximity of the particles, collisions between them happen more frequently than in gases even if particles are moving quickly in all directions.

Emissions of chlorofluorocarbons (CFCs) resulted in depletion of a protective barrier in Stratosphere layer of the atmosphere .

Option B is correct.

When gaseous CFCs slowly rise into the stratosphere, they are broken down by strong ultraviolet radiation, release chlorine atoms, and then react with ozone molecules to deplete the ozone layer. When chlorofluorocarbons (CFCs) are heavier than air, they reach the Stratosphere. Because the Earth's atmosphere is always moving and mixes the chemicals that are added, CFCs reach the stratosphere. It is true that CFC molecules are several times heavier than air.

Emissions of CFCs Due to their effects on the ozone layer, a group of chemicals known as chlorofluorocarbons, or CFCs, were widely banned. More of these compounds, which are also potent greenhouse gases, are being released from unidentified sources. Despite a global ban on their production, levels of some ozone-damaging gases are rising.

The nutrient which provide more energy is C. Lipids

Among the given options, lipids provide the most energy per unit mass. Lipids, also known as fats, are a concentrated source of energy in the diet. When metabolized, lipids yield approximately 9 kilocalories (kcal) of energy per gram.

Carbohydrates, including sugars and starches, provide approximately 4 kcal of energy per gram. They are a readily available source of energy for the body, particularly for short-term energy needs. Proteins also provide approximately 4 kcal of energy per gram. However, their primary role is not as an energy source but rather as the building blocks for tissues, enzymes, and other important molecules in the body.

Vitamins, on the other hand, do not provide significant energy. They are essential for various biochemical processes in the body but do not contribute directly to energy production.

It is important to note that while lipids provide the most energy per gram, the overall balance and variety of nutrients in a diet are crucial for maintaining optimal health. Nutrient needs vary based on individual factors, such as age, sex, activity level, and overall health goals. Therefore, Option C is correct.

In the given equation, Ek represents the kinetic energy of an object.

Kinetic energy (Ek) is a form of energy associated with the motion of an object. It is dependent on both the mass (m) and the velocity (v) of the object.

The equation Ek = (1/2)m\(v^2\) represents the formula to calculate the kinetic energy of an object.

The symbol "Ek" is commonly used to represent kinetic energy in scientific calculations and equations. By plugging in the values of mass and velocity into the equation, one can calculate the amount of kinetic energy possessed by the object.

The kinetic energy of an object increases with both its mass and velocity. As the mass increases, the object has more particles in motion, contributing to higher kinetic energy.

Similarly, as the velocity increases, the speed at which the object moves also increases, resulting in greater kinetic energy.

Therefore, understanding and calculating kinetic energy is important in various scientific and engineering applications, such as studying the movement of objects, analyzing collisions, or designing efficient systems.
