Answer to Question #168315 in General Chemistry for Juan Lopez

Question

Solid sodium metal is added to liquid water to produce hydrogen gas and aqueous sodium hydroxide.

1. Write the balanced reaction.

2. If 24.5 g of water were reacted, how many moles is that?.

3. If 8.95 moles of hydrogen gas were produced, how many germs is that?.

4 If 3.45 moles of sodium hydroxide are produced, how many moles of sodium metal reacted?

5. What type of reaction is this?.

Answer 1

1.)2Na+ 2H2O= 2NaOH + H2

2.) 24.5g of water is equivalent to

=24.5/18=1.36moles

3.)mass=$Moles× rfm$

= 8.95× 2= 17.9g

4) mole ratio 1:1

There 3.45mole of Na reacted

5)redox reaction
