Cu + 2HCI → Cu²⁺ + 2CI⁻ + H2(g)
has an overall reduction potential of –0.34 V
The correct option is:
The reaction is not spontaneous and will require energy to proceed.
Since the overall reduction potential is negative,the reaction is not spontaneous and it requires energy to proceed.
The one that will dissolve most quickly is : D. a tablespoon of ultrafine sugar
Unlike any other type of sugar, ultrafine sugar tend to have smaller crystal size. Which means that this substance will dissolve easier if it put into liquid such as tea or water
hope this helps
