Consider this reaction: 2al(s) + 3 cucl2(aq) → 2alcl3(aq) + 3 cu(s) if the concentration of cucl2 drops from 1.000 m to 0.655 m
kirza4 [7]
The average rate of reaction over a given interval can be calculated by taking the difference of concentration on a particular given reactant, and dividing it by the total time. In this case, (1.00 M - 0.655 M)/30 s = 0.0115 M/s, or 0.0115 mol/L-s, and this is the final rate of reaction.

What role does valence electrons play in reactivity for an element?
kirza4 [7]

Explanation:

The valence electrons within an atom is the number of electrons in its outermost shell.

These electrons are used by an atom to react with one another. They  determine the extent to which an atom is ready to combine either by losing, gaining or sharing these electrons.

  • Every atom desires to have a completely filled outermost shell.
  • Only the elements in group 8 have a complete octet.
  • The need to attain stability is driven by the number of electrons in their valence shell.
  • Therefore, some atoms are very reactive.
  • Those needing one electrons to complete their octet and also those that must lose one electron are very reactive.

What is a result of the unequal electron sharing in a water molecule?
Katarina [22]

Answer:

The right choice is  c. Water molecules have a weakly positive hydrogen end.

Explanation:

The unequal sharing of electrons in water molecule gives a slight negative charge near its oxygen atom ( see image below) and a slight positive charge near its hydrogen atoms. A neutral molecule that has a partial positive charge at one end and a partial negative charge at the other, it is a polar molecule.

so

a. Water molecules have a nonpolar bond.

It is wrong choice because water has polar bond .

b. Water molecules have a weakly positive oxygen end.  

Also, a wrong choice due to water molecule gives a slight negative charge near its oxygen atom.

c. Water molecules have a weakly positive hydrogen end.  

This is the right choice.

d. Water molecules have two oxygen and two hydrogen atoms

It is wrong choice because water has one oxygen and two hydrogen atoms

<u>So, the right choice is</u>

c. Water molecules have a weakly positive hydrogen end.
