Answer:

The correct answer is option e.

Explanation:

P_4+ 5O_2 \rightarrow P_4O_{10}

Moles of phosphorus pent-oxide :

\frac{14.2 g}{284 g/mol}=0.05 mol

According to reaction, 1 mole of phosphorus pent-oxide is obtained from 5 moles of oxygen gas.

Then 0.05 mole of  phosphorus pent-oxide will be obtained from:

\frac{5}{1}\times 0.05 mol=0.25 mol

Hence,the correct answer is option e.

1) How much water must be added to 500.mL of 0.200 M HCI to produce a 0.150M solution?
zloy xaker [14]

Answer:

1)

(500.mL)(.200M)/.150M = 667 mL

667mL - 500mL = 167mL of water is needed

2)

1.0 L = 1000mL

M1 V1 = M2 V2

(1.6 mol/L) (175 mL) = (x)(1000mL)

x = .28M

Write the ground state electron configuration of zn using the noble-gas shorthand notation.
V125BC [204]
Atomic Number of Zinc is 30, means it contains 30 electrons. So, its electronic configuration is as follow,

                                    1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰
As,
          1s², 2s², 2p⁶, 3s², 3p⁶  =  Argon
So,
Electronic configuration of Zinc in shorthand notation is as follow,

                                     [Ar] 4s², 3d¹⁰

Consider the reaction below.
SpyIntel [72]
Water is an amphoteric compound. This means it could be a base or an acid, depending on the substance it is to be reacted with. In this case, water is a base because HF is an acid. Now, if the reactant is an acid, its form after the reaction is called the conjugate pair. Since HF became F⁻, <em>the acid-conjugate base pair is: HF and F⁻.</em>
