Answer: The electronic configuration of Chlorine is 1s^22s^22p^63s^23p^5

Explanation: Electronic configuration is the distribution of electrons of an atom of molecule in atomic or molecular orbitals respectively.

Chlorine is an element present in group 17 of the periodic table. It's atomic number is 17.

Number of electrons = Atomic number

Number of electrons in Cl atom = 17

Electronic configuration of Cl will be 1s^22s^22p^63s^23p^5

If 0.5 mole of zn is added to hydrochloric acid containing 0.6 mol of hcl, which reactant is in excess
ser-zykov [4K]
The balanced equation for the reaction is as follows;
Zn + 2HCl --> ZnCl₂ + H₂
stoichiometry of Zn to HCl is 1:2
limiting reagent is the reactant that is fully consumed in the reaction.
the amount of product formed depends on amount of limiting reactant present.
The excess reactant is when it has been provided in excess and only a fraction of the provided amount is used up in the reaction.
Amount of Zn moles - 0.5 mol
Amount of HCl moles - 0.6 mol
If Zn is provided, number of HCl moles reacted - 0.5 x 2 = 1.0 mol of HCl is required, but only 0.6 mol of HCl is provided.
HCl is therefore the limiting reactant, 
Number of Zn moles required - 0.6 mol /2 = 0.3 mol
But 0.5 mol are given, therefore 0.2 mol of Zn is in excess

The balanced chemical equation below represents the formation of magnesium chloride.
Novay_Z [31]

Answer:

C. 33.6L

Explanation:

Based on the reaction, 2 moles of HCl reacts producing 1 mole of hydrogen.

To solve this question we must find the moles of hydrogen produced using the reaction. Then, with combined gas law (PV = nRT) we can find the volume produced:

<em>Moles H2:</em>

3.00 moles HCl * (1mol H2 / 2mol HCl) = 1.50 moles H2 are produced

<em>Volume:</em>

PV = nRT

V = nRT / P

<em>Where P is pressure = 1atm at STP</em>

<em>V is volume = Our incognite</em>

<em>n are moles of the gas = 1.50 moles</em>

<em>R is gas constant = 0.082atmL/molK</em>

<em>T is absolute temperature = 273.15K</em>

<em />

V = nRT / P

V = 1.50mol*0.082atmL/molK*273.15K / 1atm

V = 33.6L
