Compounds X has the formula C7H15Cl; Y is C7H15Br. X undergoes base-promoted E2 elimination to give a single alkene product Z. Y likewise reacts under similar conditions to give a single alkene product that is isomeric with Z Catalytic hydrogenation of Z affords 3-ethylpentane. X readily reacts in SN2 fashion with sodium iodide in acetone. Y does not undergo a similar SN2 reaction. Propose structures for X and Y.

Explanation:

Answer:

It’s the other answer, thermal energy

Explanation:

I hope y’all get a good grade

Thermal energy refers to the sum of the kinetic energy of all the particles in an object. Hence, the correct option is B.

Thermal energy is a form of internal energy associated with the random motion and vibrations of atoms and molecules within a substance. It is directly related to the temperature of the object, as the temperature is a measure of the average kinetic energy of the particles. The higher the temperature, the greater the thermal energy of the object.

Potential energy (A) refers to the energy that an object possesses due to its position or state, such as gravitational potential energy or elastic potential energy.

Temperature (C) is a measure of the average kinetic energy of the particles in a substance and is not the sum of the kinetic energy of all the particles. However, it is related to thermal energy as it provides information about the average kinetic energy.

Heat (D) refers to the transfer of thermal energy from one object to another due to a temperature difference. It is not the sum of the kinetic energy of the particles in an object but rather the energy transfer between objects with different temperatures.

Answer:

The 3rd equation.

Cl2 + 2NaBr —> 2NaCl + Br2

Explanation:

The law of conservation of matter (mass) states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another. This implies that unbalanced chemical equation shows that matter (mass) has been created or destroyed.

Now, we shall determine which equation is balanced as follow:

1. 2Cl2 + NaBr —> 2NaCl + Br2

Reactant >>>>>>>> Product

4 Cl >>>>>>>>>>>> 2 Cl

1 Na >>>>>>>>>>>> 2 Na

1 Br >>>>>>>>>>>> 2 Br

Thus, the equation is not balanced.

2. Cl2 + NaBr —> NaCl + Br2

Reactant >>>>>>>> Product

2 Cl >>>>>>>>>>>> 1 Cl

1 Na >>>>>>>>>>>> 1 Na

1 Br >>>>>>>>>>>> 2 Br

Thus, the equation is not balanced.

3. Cl2 + 2NaBr —> 2NaCl + Br2

Reactant >>>>>>>> Product

2 Cl >>>>>>>>>>>> 2 Cl

2 Na >>>>>>>>>>> 2 Na

2 Br >>>>>>>>>>>> 2 Br

Thus, the equation is balanced.

From the illustration made above only the 3rd equation is balanced. And this is in line with the law of the Conservation of matter (mass) as matter (mass) was not created nor destroyed during the chemical reaction but was transferred to other forms.

1. option B

2. ground state Fe :  [Ar] 4s² 3d⁶

Aufbau rule

Electrons occupy orbitals of the lowest energy level

Charging electrons in the sub-shell uses the following sequence:  

1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.  

So the correct choice of answer is B.

Ground state is the state of electrons filling skins with the lowest energy levels.

Excited state is the state of electrons which occupy a higher energy level

The atomic number of Fe = 26, so electrons=26

Ground state configuration of Fe : [Ar] 4s² 3d⁶ or

This represents your theoretical yield. If the percent yield is 100%, the actual yield will be equal to the theoretical yield. However, after you do the experiment you discover that only 6.50 g of water were produced.

Since less than what was calculated was actually produced, it means that the reaction's percent yield must be smaller than 100%. This is confirmed by

Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another. This exchange results in a more stable, noble gas electronic configuration for both atoms involved. An ionic bond is based on attractive electrostatic forces between two ions of opposite charge.

Explanation:

Answer: Scientists generally thought atoms were the smallest particles that could not be broken down any further.

Explanation: Trust me

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. Scientists generally thought atoms were the smallest particles that could not be broken down any further.

Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.

In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.

Before J.J. Thomson began gathering evidence about electrons in 1897. Scientists generally thought atoms were the smallest particles that could not be broken down any further.

Therefore, Scientists generally thought atoms were the smallest particles that could not be broken down any further.
