What is the weight of 4.30 mole of sodium

Chemistry
1 answer:
Dovator [93]3 years ago
3 0

98.857g Na

To find this, set up an equation as so:

4.3 mol Na = \frac{22.99g Na}{1 mol Na}

Multiply everything on the top and divide that by everything on the bottom to get the final answer of 98.857g Na.

Hope this helps!

Answer:

Explanation:

1 =  The given chemical reaction does not follow the law of conservation of mass because,

2 = Four hydrogen atoms are present in reactant side and two hydrogen atoms are present in product side.

3 = 1 ) The given chemical reaction does not follow the law of conservation of mass because,

CH₄ + O₂     →    CO₂  + H₂O

16 g  + 32 g       44 g  +  18 g

 48 g                        62 g

Law of conservation of mass:

This law stated that mass can not be created or destroyed in chemical reaction. It just changed from one to another form.

For example:

C₂H₄   +   3O₂   →    2CO₂   +  2H₂O

28 g   + 96 g    =      88 g  +  36 g

   124  g           =      124 g

lara [203]

Answer:

Biphenyl

Explanation:

The reaction of bromo benzene with magnesium-ether solution yields a Grignard reagent.

The byproduct of this reaction is biphenyl. It is formed when two unreacted bromobenzene molecules are coupled together.

Hence, It is advised that the bromobenzene solution be added slowly to the magnesium-ether solution so that it isn't present in a high concentration, thus reducing the amount of biphenyl by-product formed.
