Question

Write a balanced chemical equation for each of the following sentence descriptions of reactions.

A. Sodium metal reacts with water to produce aqueous sodium hydroxide.
B. Silver nitrate dissolved in water reacts with copper metal to produce silver metal and aqueous copper (II) nitrate.
C. Solid copper (II) carbonate decomposed when heated to produce carbon dioxide and solid copper (II) oxide.
D. Aqueous sodium carbonate reacts with aqueous copper (II) nitrate to produce solid copper (II) carbonate and aqueous sodium nitrate.

Answer 1

2na+h20>2Na(OH) +02

Answer 2

\[2Na+H_{2}0\rightarrow 2Na(OH)+0_{2}\]

Answer 3

Oh my goodness!

\[2\text{Na}_{(s)} + 2\text{H}_2\text{O}_{(l)} \longrightarrow 2\text{NaOH}_{(aq)} + \text{H}_{2(g)}\]
Hey. Instead of asking other people to do your homework for you, why don't you study! How do you hope to learn chemistry and pass an exam?
