Art [367]3 years ago
7 0

Explanation:

Aluminium - Al

Iron Sulfate - FeSO4

The reaction is given as;

Al + FeSO₄ -->  Al₂ (SO₄) ₃ + Fe

The balanced equation is given as;

2 Al + 3 FeSO₄ -->  Al₂ (SO₄) ₃ + 3 Fe

In words it is given as;

Aluminium + Iron Sulfate --> Aluminium Sulfate + Iron

Is density a chemical or physical property of a substance?
pychu [463]

Answer:

A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.

A concentration cell consists of two sn/sn2+ half-cells. the electrolyte in compartment a is 0.24 m sn(no3)2. the electrolyte in
Vikentia [17]
A:-      sn(s) =>  Sn +2(0.24 M) + 2e-
B:-     Sn +2 (0.87 M) +2e-  =>   Sn(s) 

solution will become more concentrated and solution B become less concentrated 

Sn(s)+ Sn +2(0.87 ) ----> Sn(s) + Sn  +2(0.24)
E  =   Eo  -   0.0592 / 2 * log   [   (0.24 / 0.87 ) ]
E  = 0.0   -   0.0592 / 2   *   log ( 0.275) 
( n=2 two electrons are transferred)

E =  -0.0296 *  ( - 0.560) 
E =  0.0165 volts

Which way does heat flow?
kenny6666 [7]

Hey im happy to help!

Heat can float from one place to another, like all energy.Heat floats in solids by conduction, that happens because the molecules hit one another.Heat within the solid will flow from hot to cold.Heat will flow downward if its cold there.

Hope this helps, have a great rest of your day!

Phosphorus has three electrons in its 3p sublevel and sulfur has four. Phosphorus should have the lower ionization energy but it
Nadya [2.5K]

Answer:

B

Explanation:

First of all it is important to know that a half filled orbital is particularly stable. In phosphorus all the electrons occur singly in the 3p sublevel minimizing inter electronic repulsion hence it is more difficult to remove an electron from this energetically stable arrangement. In sulphur, electrons are paired in one of the 3p orbitals thereby lowering the energy of that level due to instability caused by interelectronic repulsion between two electrons in the same orbital.
