Answer: Option (a) is the correct answer.

Explanation:

The compound CH_{2}Cl_{2} is tetrahedral in nature. But due to difference in electronegativity of both carbon and chlorine, chlorine is more electronegative than carbon.

Whereas carbon is more electronegative than hydrogen atom.

As a result, there will be individual bond moment which is unequal and leads to net dipole moment into the molecule.

Hence, the compound CH_{2}Cl_{2} will always be polar in nature.

Thus, we can conclude that the statement molecule is always polar, describes the polarity of CH_{2}Cl_{2}.

Rx: Codeine phosphate 30 mg/tsp Tussin syrup 30mL Elixophyllin qs 240 mL Sig: 5mL qid pc hs If 5 mL of Tussin syrup contains 100
kotykmax [81]

Answer:

50 mg.

Explanation:

From the prescription, 240 ml amount is to be prepared containing 30 ml tussin syrup. As the frequency is 5 mL qid, it means 5mL of syrup is to be administered four times daily i.e. 20 mL daily. To calculate the amount of tussin taken daily,

<em>                          </em><em><u>30 mL tussin</u></em><em> = </em><em><u>X mL of tussin</u></em>

<em>                     240 mL solution    20ml solution</em>

⇒ 2.5 mL of tussin

5 ml tussin contains 100mg guafenesin,

So,

⇒ 2.5 ml of tussin contains 100x2.5/5 = 50 mg guaifenesin

A certain reaction at equilibrium has more moles of gaseous products than of gaseous reactants.(b) Write a statement about the r
mojhsa [17]

To be equal as K_p , K_c needs to be divided by (RT)^{\Delta n}

<h3>Briefly explained</h3>

When the amount of gaseous reactant is greater than the amount of gaseous product, where n_{products} < n_{reactants},

then = K_p < K_c

It's because \Delta n is negative, which places (RT) in the denominator. This is how the equation will now appear.

K_p = K_c(RT)^{-\Delta n} = \frac{ K_c}{(RT)^{\Delta n}}

Here you can observe the value of K_c  is greater than K_p. To be equal as K_p , K_c needs to be divided by (RT)^{\Delta n}

<h3>What is Δngas?</h3>

The number of moles of gas that move from the reactant side to the product side is denoted by the symbol ∆n or delta n in this equation.

Once more, n represents the growth in the number of gaseous molecules the equilibrium equation can represent. When there are exactly the same number of gaseous molecules in the system, n = 0, Kp = Kc, and both equilibrium constants are dimensionless.

<h3>Definition of equilibrium</h3>

When a chemical reaction does not completely transform all reactants into products, equilibrium occurs. Many chemical processes eventually reach a state of balance or dynamic equilibrium where both reactants and products are present.
