Answer:
2. Copper (II) carbonate plus sulfuric acid produces copper (II) sulfate and carbon dioxide and water.
- We need the "II" after copper to specify what charge it is. It's +2 because carbonate is -2.
3. Calcium hydroxide plus carbon dioxide gas produces calcium carbonate and water.
BaCl2 reacts with KOH forming KCl which is a salt and Ba(OH)2 which is the precipitate.
The initial UNBALANCED equation expressing this reaction would be:
BaCl2 + KOH .............> KCl + Ba(OH)2
Now, we need to balance this equation:
we have two moles of Cl as reactants and one mole only as product. Therefore, we will multiply the KCl in the product by 2 and the KOH in the reactants by 2.
This will balance the equation as follows:
BaCl2 + 2KOH ......> 2KCl + Ba(OH)2
Noticing this equation, we will find that:
The precipitate was formed due to the combination of the Ba2+ ion with 2 OH- ions as follows:
Ba2+ + OH- ............> Ba(OH)2
Answer:
yes answer os Na because it's electronic configuration is 1s^2,2s^2,2p^6,3s^1
It’s C because wood isn’t easy to get heat through while metal can heat up quickly.
False, as pressure increases, temperature increases, given that other factors stay the same.
