An atom has 5 electrons in its outer shell. how many unpaired electrons does it have?
lions [1.4K]

The answer is 3.

That is if an atom has 5 electrons in its outer shell, then it has 3 unpaired electrons.

As the outer shell have 1 s orbital too and that is fully filled and not available for bonding so it must have 3 unpaired electrons.

So the number of unpaired electrons in an atom that is having 5 electrons in its outer shell is 3.

What would the rate law be for the following reaction:
lana [24]

Answer:

C. Rate = k[H2]^2[O2]

Explanation:

Rate law only cares about REACTANTS. Since, rate law can only be determined experimentally, I am assuming the given reaction mechanism is elementary reaction from which we can write the rate law.

Only H2 and O2 are part of rate law since they are reactants and also the coefficient in front of H2 goes as exponent on rate law to indicate the order of H2 in the reaction.

Rate= k [H2]^2 [O2]

The ph of a substance equals −log[h+] where [h+] is the concentration of hydrogen ions. [h+] for tomato juice is 10−4. what is t
Wittaler [7]
 The   Ph  of  tomato   juice  is  calculated  as follows

Ph  =  -log (H+)

if  H+   ion  concentration   is  10^-4

Ph  is  therefore =  -log  (10^-4)  =4

the  tomato  juice  has  a  Ph  of  4

NaCl+AgNO3–>AgCl+NaNO3
Lelechka [254]

Answer:

45g of NaCl x 1mole of NaCl/58.5g

= 0.769moles of Nacl

Now Looking at the equation

1mole of Nacl produces 1mole of AgCl

so

0.769mole of NaCl will produces the same Mole of AgCl(0.769)

So the Moles of AgCl produced = 0.769

Recall

Mole = Mass /Molar Mass

Mass = Mole x Molar Mass

Molar Mass of AgCl =108 + 35.5 = 143.5

Mass of Agcl = 0.769 x 143.5

=110.35g of AgCl
