Answer:
According to the subshells, the ns subshell has a sphere-like shape, and on average, lower energy than the rest of the subshells on the same quantum level
The np subshell has two lobes opposite the origin, and on average has more energy than a ns subshell since it has one more angular node, and thus np electrons are less core-like (and further away from the nucleus).
n
d orbitals have five spatial orientations:
and n
f orbitals have seven spatial orientations
The energies are on average in increasing order for the same energy level , n as follows,
nS < nP < nD < nF
<h3><u>Answer;</u></h3>
<em> D) It can be mass produced.</em>
<h3><u>Explanation;</u></h3>
- <em><u>Synthetic materials</u></em> are those materials that are <em><u>man-made, that is they are synthesized in the lab or in industries.</u></em> They include synthetic fibers such as nylon, polyester and acrylic among others.
- <em><u>Synthetic materials</u></em> have a range of advantages over natural materials. For example, synthetic materials are durable than natural ones, they are cheap, they do not shrink and also resistant to chemicals among others.
- Additionally, synt<em><u>hetic materials such as synthetic fibers they can be mass produced in industries or in the labs. </u></em>
Heat energy can be calculated by using the specific heat of a substance multiplying it to the mass of the sample and the change in temperature. It is expressed as:
<span>
Energy = mCΔT
</span><span>Energy = 132 (0.385) (45 - 32.2)
</span><span>Energy = 650.50 J</span>
The enthalpy of formation of CF is -678.82 kJ/mol.
<h3>What is enthalpy ?</h3>
A thermodynamic system's enthalpy H is calculated by multiplying its internal energy by the product of its pressure and volume. In the equation H = U + pV, U stands for internal energy, p for pressure, and V for system volume; pV is also frequently referred to as the pressure energy P.
The amount of heat in a system under constant pressure is measured as enthalpy (H). Chemists frequently gauge how the enthalpy of chemical systems changes when reactants transform into products. The enthalpy change, which is the same thing as the heat that is absorbed or released by a process at constant pressure, is denoted by the letter H.
