Answer:
The combustion reaction is the last one, with the C4H12 compound.
Remember that all the combustion reactions has the oxygen as a substract and for products, you'll have CO2 and water.
Explanation:
Answer:
The net ionic equation:

Explanation:
The given chemical reaction is as follows.

The total ionic equation is as follows.

Similar ions on the both sides of the reaction will be cancelled.
The remaining reaction is

Therefore, the net ionic reaction is as follows.

Answer:
The electrical current in electrolysis act as a catalyst driving a reaction in forward direction because when the electric current is allowed to the electrodes, the particles in the solution starts movement towards electrodes. Before this current, the particles inside the solution are static. If a solution contain sodium chloride so when the electrical current is passed. Sodium moves to the negative electrode while chlorine moves towards positive electrode and both the atoms are separated from each other and the reaction is completed.
Hi. The first one is correct. They have no charge and are in located inside the nucleus.
Answer:
23.175g
Explanation:
0.45 mole of NaBr is in 1 liter
? moles of NaBr is in 0.50 liter
0.50 × 0.45 = 0.225 of NaBr
1 mole of NaBr = 23 + 80 = 103g
0.225 moles of NaBr = ?
0.225 × 103 = 23.175g
