Answer:because it isnt flammable
Explanation:water can not be burned
Answer:
Acids have a high concentration of [H⁺] ions
Explanation:
In order to know about the acids, a solution is acidic when pH < 7
As pH is lower than 7, the pOH > 7
When pH = 7, solution is neutral
When pH is greater than 7, solution is basic
pH = - log [H⁺]
pOH = - log [OH⁻]
Imagine a solution of pure HCl 0.2 M
HCl → H⁺ + OH⁻
[H⁺] = 0.2 M → pH = - log 0.2 → 0.69
pH + pOH = 14
pOH = 14 - 0.69 = 13.31
10^-pOH = [OH⁻] → 10⁻¹³°³¹ = 4.89ₓ10⁻¹⁴
In conclussion [H⁺] > [OH⁻]
A general formula of an acid always start with an hydronium ion or H+. The general formula of an acid have to end with an anion. As acids, these compounds are named starting with the prefix "hydro-," then adding the first syllable of the anion, then the suffix "-ic."
Answer:
yes, they were
Explanation:
The history of the metric system began in the Age of Enlightenment with notions of length and weighttaken from natural ones, and decimal multiples and fractions of them. The system became the standard of France and Europe in half a century. Other dimensions with unity ratios[Note 1] were added, and it went on to be adopted by the world.
