Allena and Charissa were discussing whether Cl2 is an element or a compound. Allena said that it is an element because it has on

ly one type of atom. Charissa said that it is a compound because it has more than one atom. Who is correct?
Allena is correct. It is an element because it is only one atom.


Charissa is correct. It is a compound because it has a two.


Charissa is correct. It is a compound because it is made of more than one atom.


Allena is correct. It is an element because it is only made of chlorine atoms.

Answer is: Allena is correct. It is an element because it is only made of chlorine atoms.
A chemical element bonded to an identical chemical element is not a chemical compound since it is made from only one element and not from two different elements. Chlorine is molecule, but not compound.

Calculate the standard cell emf for the reaction: ClO3−(aq)+3Cu(s)+6H+(aq)→Cl−(aq)+3Cu2+(aq)+3H2O(l) Pt is used as an inert elec
Rama09 [41]

<u>Answer:</u> The standard EMF of the cell is 1.11 V

<u>Explanation:</u>

For the given chemical equation:

ClO_3^-(aq)+3Cu(s)+6H^+(aq.)\rightarrow Cl^-(aq.)+3Cu^{2+}(aq.)+3H_2O(l)

The half reaction follows:

<u>Oxidation half reaction:</u>  Cu(s)\rightarrow Cu^{2+}+2e^-;E^o_{Cu^{2+}/Cu}=0.34V    ( × 3)

<u>Reduction half reaction:</u> ClO_3^-(aq.)+6H^+(aq.)+6e^-\rightarrow Cl^-(aq.)+3H_2O(l);E^o=1.45V

To calculate the E^o_{cell} of the reaction, we use the equation:

E^o_{cell}=E^o_{cathode}-E^o_{anode}

Substance getting oxidized always act as anode and the one getting reduced always act as cathode.

Calculating the E^o_{cell} using above equation, we get:

E^o_{cell}=1.45-0.34=1.11V

Hence, the standard EMF of the cell is 1.11 V

Between HClO3 and HIO3, which is stronger and why? Question 16 options: 1) HClO3 is stronger because chlorine is in a higher oxi
natima [27]

Answer:

2) HClO3 is stronger because chlorine is more electronegative than iodine.

Explanation:

The more electronegative the element is the more strong or acidic it becomes.

Chlorine being more electronegative than Iodine makes it easier for it to pull the electron of hydrogen more strongly and hence has a higher tendency to release a H+ unit. Hence that makes it stronger.
