Answer:
61.4 %
Explanation:
Let's consider a generic chemical reaction.
Reactants ⇒ Products
The theoretical yield is the maximum mass of product that theoretically can be obtained from the chemical reaction.
The actual yield is the mass of the product obtained from the reaction.
The percent yield is:
Percent yield = actual yield / theoretical yield × 100%
Percent yield = 60.9 g / 99.2 g × 100% = 61.4 %
Answer:
They may have different phenotypes because of differences in their environments, such as nutrition and healthcare. Why might genetically identical twins have different phenotypes? Any genes on the same chromosome could be linked genes, whereas only genes on sex chromosomes can be sex-linked genes.
Explanation:
Answer:
980,536.2 grams
Explanation:
The mass of a compound is equal to its moles times its molar mass.
The molar mass of PCl3 is 137.33 g/mol
137.33 x 7.14 x 10^3 = 980,536.2
A combination reaction<span> is a </span>reaction<span> in which two reactants combine to form one product. It is also called a synthesis reaction. A characteristic to this type of reaction would be that there would always be only one product. Hope this answers the question. Have a nice day. </span>
The quantum mechanical model is used to describe the energy and most likely location of an electron.
Answer: Option A
<u>Explanation:
</u>
The quantum mechanical model leads to the introduction of quantum numbers representing the energy levels, sub-shells, orbitals as well as spin states of the electrons. So according to the quantum numbers we can perfectly define the position and energy of any electron in an element.
According to Pauli’s principle, any two electron cannot be having same set of quantum numbers. So, using the principle quantum number, azimuthal quantum number, magnetic and spin quantum number, we can define the energy and location of an electron in the atom.
