Answer:
What Do Nails Do? Nails protect the sensitive tips of fingers and toes. We don't need our nails to survive, but they do support the tips of our fingers and toes, protect them from injury, and help us pick up small objects.
Answer:
2NaOH + 2Al +2H2O = 2NaAlO2 +3H
Explanation:
Aluminum is an amphoteric element it reacts with both bases and acids to form a salt and hydrogen gas.The reaction is highly exothermic.
Answer: 1.0 x 10^-3M
Explanation:
The solution with pH 3 is said to be acidic because pH values less than 7 are regarded as acidic, and will produce hydrogen ions.
Mathematically, pH is expressed as
pH = -log(H+)
where H+ is the concentration of hydrogen ion
So, pH calculations are as follows
3 = -log(H+)
(H+) = Antilog (-3)
(H+) = 0.001M
Place (H+) in standard form
(H+) = 1.0 x 10^-3M
Thus, the value of hydrogen ion (H+) in the solution with pH 3 is 1.0 x 10^-3M
