Elements that belong to the same period which is seen horizontally in the periodic table have different properties. Elements with similar properties are seen in columns or groups. Elements in the same period have similar principal quantum number and belong to the same principal shell. Hence the answer is that t<span>hey have different properties that repeat across the next period</span>.
B: Mitochondria
They are the energy converters in the cell
Nucleus is the "brain" (it controls cell functions)
Endoplasmic Reticulum is like the "post office" (transports information and materials)
Golgi Bodies package macromolecules for transport within the cell

Given:
The Kp for the reaction below is 1.49 · 10⁸ at 100.0°C (a balanced reaction)
In an equilibrium mixture of the three gases.
p CO = p Cl₂ = 2.22 · 10⁻⁴ atm.
Question:
The partial pressure of the product, phosgene (COCl₂), is __ atm.
The Process:
Let us write the equilibrium constant in terms of pressure based on the reaction above.
We set p COCl₂ as the subject to be asked.
Substitute all the data above into the equation.
Thus, the partial pressure of the product, phosgene (COCl₂), is 7.34 atm.

Answer:
Benzoic acid
Explanation:
In this case we have a Grignard reaction in which we go from a formula of C6H5Br to C7H6O2. In other words, we add 1 carbon to the molecule. The only way to add one carbon to this molecule is using as a reagent. When this compound is used as electrophile a carboxylic acid is produced.
Respect to the NMR info, we have a <u>downfield singlet signal</u> at 12.1 ppm which is characteristic of the <u>acid hydrogens</u> in the carboxylic acids (see figure 1). When a carboxylic group is added to the benzene we will obtain the <u>benzoic acid</u> which fits with the formula and the NMR info given.
