Answer:
its the same thing as 3 x3 or 3+3 it always come´s back as 9 or 6 Because of life
Explanation:
Answer is: the hydronium ion (H₃O⁺) concentration is greater than hydroxide ion (OH⁻)<span> concentration.
</span><span>Bases (more hydroxide ions than hydronium ions) turn red litmus paper blue and acids (more hydronium ions than hydroxide ions) turn blue
litmus paper red.
</span><span>Acids and bases have opposite properties and have the ability to
neutralize each other. Acids taste sour, give sharp stinging pain
in a wound and react with metals to produce hydrogen gas.</span>
Answer:
<span>Primary alcohols oxidize to form Carboxylic Acids.
Explanation:
Primary Alcohols when treated with Oxidizing agents like </span>K₂Cr₂O₇ and CrO₃<span> produces carboxylic Acids as a final product. This oxidation to Carboxylic Acid first passes through Aldehydes and then is oxidized to carboxylic Acid.
</span> As K₂Cr₂O₇ and CrO₃ are strong oxidizing agents, if a mild oxidizing agent like <span>Pyridinium Chlorochromate (PCC) is used then primary Alcohol will convert into Aldehyde.</span>
So, on reacting with strong oxidizing agent primary alcohol will produce carboxylic acids via aldehydes and when treated with mild oxidizing agent primary alcohol will produce aldehyde.
Answer:
Chemical element, metallic, symbol Mg, situated in group IIa in the periodic table, atomic number: 12, atomic weight: 24,312. ... Magnesium is known for a long time as the lighter structural metal in the industry, due to it's low weight and to it's capability of forming mechanically resistant alloys.
The correct answer is 2.73.
HF is a weak acid which partially dissociates to release H+ and F-
HF → H⁺ + F⁻
Initial 0.0050 0 0
Change -x +x +x
Equilibrium 0.0050–x +x +x
Solve by using the equilibrium expression: = [H⁺] [F⁻]/ [HF]
6 .8 x 10⁻⁴= x. x / 0.0050 –x
6 .8 x 10⁻⁴= x² /0.0050
x² = 6 .8 x 10⁻⁴ x 0.0050
x² = 3.4 x 10⁻⁶
x = 3.4 x 10⁻⁶
[H⁺] = 1.84 x 10⁻³
pH = - log [H⁺] = - log (1.84 x 10⁻³)
pH = 2.73
