Explanation:

Bailee explained that when traveling to the moon  mass of the objects is which changes when the gravitational pull changes. Bailee is incorrect. Both the mass and weight will change. Option C is correct.

Mass is the physical quantity of any substance or object and weight is the measurement of amount of force acting on a particulate body of the mass.

At the moon both the  mass and weight is divided by 6 means the  mass and weight is six times lighter then the expected  mass and weight on earth.

Therefore, Bailee is incorrect. Both the mass and weight will change. Option C is correct. which changes when the gravitational pull changes

Answer:

H ₂O ₂

Explanation:

Hydrogen peroxide

Vanadium  and the oxide is V2O5.

We have the information that the  element which has an atomic mass between  40 and 55  reacts with oxygen. This compound must e ionic so we can write; 2M + x/2O2 --->M2Ox

Mass of oxygen utilized in the reaction is; 3.708 g - 2.077 g  = 1.631 g

Number of moles of oxygen used = 1.631 g/32g/mol = 0.051 moles

Number of moles of the metal =   2.077 g/M

Thus;

2.077 g/M  * x/4 = 0.051 moles

2.077x/4M =  0.051 moles

2.077x = 0.204M

M = 2.077x /0.204

M = 10.181x

Given that x could be 4 or 5, we have to agree that x =5 which gives a mass of  50.93 thus M is Vanadium  and the oxide is V2O5.

The mass of water produced when 9.60 g of butane reacts with excess oxygen is 14.85 gram.

The chemical reaction between substances, usually considering oxygen and usually accompanied by the generation of heat and light in the form of flame is called as combustion reaction.

C4H10(g) + 13 /2 O2(g) → 4CO2(g) + 5H2O(l)

Moles of butane = 9.60⋅g / 58.12⋅g⋅mol−1

= 0.165mol.

We assume complete combustion, and know that each mole of butane gives off 5 mol of water upon combustion.

Given that we know the molar quantity of butane, we simply perform the operation,

= 5 × 0.165 × 18.01

= 14.85 gram

Thus, the mass of water produced when 9.60 g of butane reacts with excess oxygen is 14.85 gram.

Niels Bohr's 1913 model depicts that the atom has a small, positively charged nucleus which surrounded by electrons that travel in circular orbits around the nucleus.

The Bohr model, is a representation of the structure of atoms, especially that of hydrogen, The Bohr Model is a universal model in which the negatively charged electrons orbit a small, positively charged nucleus like the planets.

In the Bohr model, electrons are pictured as traveling in circles at dissimilar shells, depending on which element you have. The Bohr model is a proportional primitive model of the hydrogen atom, in contrast to the valence shell mode

Answer:

Volume = 3.4 L

Explanation:

In order to calculate the volume of CO₂ produced when 15.2 g of CaCO₃ is heated, we need to first write out the balanced equation of the thermal decomposition of CaCO₃:

CaCO₃ (s) + [Heat] ⇒ CaO (s) + CO₂ (g)

Now, let's calculate the number of moles in 15.2 g CaCO₃:

mole no. = \(\mathrm{\frac{mass}{molar \ mass}}\)

                 = \(\frac{15.2}{40.1 + 12 + (16 \times 3)}\)

                 = 0.1518 moles

From the balanced equation above, we can see that the stoichiometric molar ratios of CaCO₃ and CO₂ are equal. Therefore, the number of moles of CO₂ produced is also 0.1518 moles.

Hence, from the formula for the number of moles of a gas, we can calculate the volume of  CO₂:

mole no. = \(\mathrm{\frac{Volume \ in \ L}{22.4}}\)

⇒ \(0.1518 = \mathrm{\frac{Volume}{22.4}}\)

⇒ Volume = 0.1518 × 22.4

                 = 3.4 L

Therefore, if 15.2 g of CaCO₃ is heated, 3.4 L of CO₂ is produced at STP.

The statement which interpret the object motion is the object moves with a constant positive velocity and then stops moving. The slope represents velocity. Therefore, option B is correct.

The term velocity is defined as vector expression representing the change in position over time of an object or particle. It is also known as speed.The unit of velocity magnitude is the meter per second (m/s).

A positive velocity merely indicates that an object is moving in the coordinate system's positive direction, whereas a negative velocity denotes that the item is going in the opposite direction.

The balanced equation for the reaction between solid calcium cyanide and liquid water to generate calcium hydroxide and hydrogen cyanide would be \(Ca(CN)_2 (s) + 2H_2O(l)-- > Ca(OH)_2 (aq) + 2HCN (aq)\)

The reaction between solid calcium cyanide and liquid water to generate calcium hydroxide and hydrogen cyanide would be written as follows:

The chemical formula of solid calcium cyanide = \(Ca (CN)_2 (s)\)

The chemical formula of liquid water = \(H_2O (l)\)

The chemical formula of calcium hydroxide in solution = \(Ca(OH)_2 (aq)\)

The chemical formula of hydrogen cyanide in solution = \(HCN (aq)\)

Bringing all the species together, the equation for the reaction would be:

But the above equation is not balanced. The number of hydrogen and cyanide atoms is not balanced. Balanced chemical equations always have an equal number of every atom in the reactants and in the products.

When cyclohexene is mixed with a sulfonitric mixture (H2SO4/HNO3), it reacts to form nitrocyclohexane and sulfur dioxide.

This reaction proceeds in two steps. Firstly, cyclohexene undergoes electrophilic addition with the nitronium ion (NO2+), which is generated from the reaction between HNO3 and H2SO4. This results in the formation of nitrocyclohexane, giving the initial pale yellow color to the solution.

In the second step, nitrocyclohexane reacts with the excess sulfuric acid present in the mixture. This step is highly exothermic, releasing a significant amount of energy. The sudden release of energy causes an explosion. The exact mechanism of the explosive reaction is complex, involving the generation of reactive intermediates. It is believed that the reaction proceeds via a radical mechanism, where nitrocyclohexane decomposes into highly reactive nitrogen and carbon-centered radicals. These radicals further react with sulfur dioxide, which is produced in the reaction, to form stable compounds. As a result, the solution turns dark brown after the explosion.

Answer:

heat energy released by the substance

The energy change that takes place during deposition is that heat energy is released by the substance. This statement is true about deposition.

Deposition is a phase transition that occurs when a gas is converted directly to a solid without passing through the liquid state. During deposition, energy is released by the gas particles and absorbed by the surface, resulting in a decrease in the energy of the gas particles and an increase in the energy of the surface particles.As a result, the substance releases heat energy as it changes from a gas state to a solid state.
