Al2so4+NaOH =Naso4+AlOH= so I think it’s B not sure
Answer:
last one is the correct and most suitable option.
Hope it helps!!!
Since I cannot find the choices, I will tell you some of the benefits of electroplating in different industries. You can compare these benefits with the choices you have and choose the best fit.
1- Forms a protective layer to protect the material from the conditions of the atmosphere as the corrosion
2- Improves the appearance of some inexpensive materials and makes them look more appealing
3- Can enhance the electrical conductivity of materials
4- electroplating of zinc-nickel or gold can survive high temperatures
5- Sometimes hardens the material
6- Increases the thickness of the material
It must be noted that our compound contains only two components, N and O. From the given masses, the total mass of the compound should be 300 g.
Then, we divide the masses of each component by the total mass and multiply the quotients by 100% to get the % compositions
N = (222.6 g / 300 g) x 100% = 74.2%
O = (77.4 g / 300 g) x 100% = 25.8%
