The lab experiment introduces you to the chemistry of elemental copper. Copper will undergo several chemical transformations, represented by the chemical formulas given. What is the correct sequence of chemical transformations with the correct phases? Begin with 1 and and with 6. C u ( N O 3 ) 2 ( a q ) Choose... C u ( s ) Choose... C u ( s ) wire Choose... C u S O 4 ( a q ) Choose... C u ( O H ) 2 ( s ) Choose... C u O ( s ) Choose...

1. Cu(s) 2. Cu(NO3)2 (aq) 3. Cu(OH)2 (s) 4. CuO (s) 5. CuSO4 (aq)  6. Cu(s)

Explanation:

relative humidity is a measure of the amount of moisture in the air relative to the total amount of moisture the air can hold.

so d

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
