why does the moon and the earth have the same mass

Answer:

Explanation:

The balanced chemical equation for the reaction between carbon monoxide (CO) and iron(III) oxide (Fe2O3) is:3CO + Fe2O3 -> 2Fe + 3CO2From this equation, we can see that 3 moles of carbon monoxide react with 1 mole of iron(III) oxide to form 2 moles of iron.Therefore, if 0.9 moles of carbon monoxide react, we can calculate the amount of iron formed using the following steps:Use stoichiometry to determine the amount of iron(III) oxide needed for the reaction. Since there is excess iron(III) oxide, the amount of iron(III) oxide needed is equal to the amount of carbon monoxide used in the reaction. So, the amount of iron(III) oxide used is also 0.9 moles.Use stoichiometry again to determine the amount of iron formed. Since 3 moles of carbon monoxide react with 2 moles of iron, the ratio of moles of iron to moles of carbon monoxide is 2/3. Therefore:0.9 mol CO x (2 mol Fe / 3 mol CO) = 0.6 mol FeSo, 0.6 moles of iron is formed when 0.9 moles of carbon monoxide reacts with excess iron(III) oxide.

the answer is that it is a

The cations that are more likely to undergo rearrangement are  II and III Option C

Cation rearrangement is a phenomena that causes cations, which are positively charged ions, to reorganize themselves under specific conditions. The term "cation rearrangement " describes the movement of ions inside a substance or solution that is caused by a variety of elements, including concentration gradients, electric fields, or chemical reactions.

Rearrangements influence the mobility and redistribution of cations inside substances or solutions, which can have a significant impact on the system's behavior and characteristics.

Propionic acid, C3H7COOH, has an equation for its acidic equilibrium that looks like this: C₃H₇COOH (aq) + H₂O (l) ⇌ C₃H₇COO⁻ (aq) + H₃O⁺ (aq).

A system must satisfy the three equations of equilibrium, Sum Fx = 0, Sum Fy = 0, and Sum M = 0, in order to be in equilibrium. Start with the equations for the sum of the forces. Dividing the diagonal forces into their component parts would be the most straightforward technique to solve these force systems.

The chemical reaction between the reactants both before and after the reaction is complete is referred to as an equilibrium reaction (i.e., a thermodynamic equilibrium state). The evaporation of water into vapor is an illustration of an equilibrium reaction.

The pressure inside the tire is approximately 1.970796 newtons per square centimeter (N/cm²) when measured in those units.

To convert the pressure from pounds per square inch (psi) to newtons per square centimeter (N/cm²), we need to use the conversion factors between these units.

First, let's convert pounds to newtons:

1 pound = 0.45359237 kilograms

1 kilogram = 9.80665 newtons

Next, let's convert square inches to square centimeters:

1 square inch = 6.4516 square centimeters

Now, we can perform the conversion:

1 psi = (0.45359237 kg) × (9.80665 N/kg) / (6.4516 cm²)

≈ 0.070307 N/cm²

Therefore, the pressure inside the tire of 28.0 psi is approximately equal to 28.0 × 0.070307 N/cm², which is approximately 1.970796 N/cm².

A. Depolarization is taking place as the action potential in neuron B compared to neuron A rises from a negative to a positive potential.

B. Na+ ions have the greatest impact at time 0. The electric potential becomes positive due to the inward migration of Na+ ions, causing the cell to depolarize.

C. The depolarization is brought on by the inward influx of Na+ ions through voltage-gated Na+ channels.

A summary of the C4 plants is given below:

The Hatch-Slack pathway, also known as C4 carbon fixation, is one of three recognized photosynthetic carbon fixation pathways in plants.

The names are a result of Marshall Davidson Hatch and Charles Roger Slack's discovery in the 1960s that some plants, when given 14CO2, integrate the 14C label into four-carbon molecules first.

Corn, sorghum, sugarcane, millet, and switchgrass are examples of C4 plants. C3 plants are often more prolific and efficient at photosynthesizing in cooler conditions because C4 morphological and biochemical adaptations demand more energy and resources from the plant.

The bond energy of the products (300J) is lower than that of the reactants (500J), it indicates that energy is being released to the surroundings. This release of energy in the form of heat is characteristic of exothermic reactions.This chemical reaction can be considered an exothermic reaction.

In exothermic reactions, the bond energy of the reactants is higher than the bond energy of the products. In this case, the bond energy of the reactants is 500J, while the bond energy of the product is 300J. The difference in bond energy between the reactants and the products represents the energy released during the reaction.  The bond energy of the products (300J) is lower than that of the reactants (500J), it indicates that energy is being released to the surroundings. This release of energy in the form of heat is characteristic of exothermic reactions. Exothermic reactions are often accompanied by an increase in temperature in the surroundings. Examples of exothermic reactions include combustion reactions, where a fuel reacts with oxygen to produce heat and light, or reactions that involve the formation of more stable compounds. In this particular chemical reaction, the decrease in bond energy from the reactants to the products suggests that energy is being released, making it an exothermic reaction.

The change in boiling point of C6H14 in benzene is 2.257 degree Celsius.

What is boiling point?

The boiling point is the temperature at which vapor pressure of the liquid is equal to the atmospheric pressure or the temperature at which the liquid phase turns into vapor state.  The boiling point of pure water at sea level is 100 degree Celsius.

The change in boiling point can be calculated as,

ΔTb = Kb x m

where ΔTb is change in boiling point, Kb is Ebullioscopic constant and m is molality of the solute.

ΔTb = (2.65 degree Celsius / m) x 0.852m = 2.257 degree Celsius.

Therefore, the change in the boiling point of 0.852m solution of C6H14 in benzene is 2.257 degree Celsius.

The force that helps keep the Earth in its orbit around the Sun is the gravitational force.

The Sun has a massive gravitational pull due to its large mass, which causes the Earth to be attracted towards it. This force of attraction is what keeps the Earth in its stable orbit around the Sun.

The gravitational force between the Sun and the Earth is balanced by the Earth's velocity and centrifugal force, which allows it to maintain a stable orbit around the Sun.

The gravitational force is the attractive force that exists between any two objects with mass. The magnitude of the gravitational force between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them.

This means that the larger the mass of the objects and the closer they are to each other, the stronger the gravitational force between them.

In the case of the Earth and the Sun, the Sun is much more massive than the Earth, which means it exerts a much stronger gravitational force on the Earth. The Earth is constantly falling towards the Sun due to the force of gravity.

However, the Earth also has a tangential velocity that keeps it moving in a circular orbit around the Sun. This is known as centrifugal force, which is the force that acts on an object moving in a circular path, pulling it away from the center of the circle.
