It should be A) 0
because acids are from PH0-PH6 and basics are from PH7-PH14
Hope this helps!
Good luck!
Answer: Speed has the dimensions of distance divided by time.
Explanation:
Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour or, in the US and the UK, miles per hour.
SI unit: m/s, m s−1
Common symbols: v
Dimension: L T−1
<span>Cell references in a formula are called electrode potentials. Electrode potentials are standard voltages for half-cell potentials. All half-cell potentials use the Standard Hydrogen Electrode (SHE) as a universal reference for redox reactions. For hydrogen, the standard electrode potential is zero for all temperatures.</span>
Following are the advantages of corrosion: A layer of protection: A layer of oxide is formed in surface corrosion, which protects the inner metal from corrosion. Sacrificial anodes such as zinc is used as a preventive measure to stop corrosion of other metals.
