Answer:
The Californian red wine (pH 3.5) has a hydrogen concentration of 0.00032M
The italian white wine (pH 2.9) has a hydrogen concentration of 0.00126 M
Explanation:
<u>Step 1:</u> Data given
Wine 1 has a pH of 3.5
Wine 2 has a pH of 2.9
Wine 2 is more acid so should have more hydrogen ions
<u>Step 2:</u> Calculate hydrogen concentration
pH = -log [H+]
Wine 1: pH = 3.5 = -log[H+]
[H] = 10 ^-3.5 M = 0.00032 M
Wine 2: pH =2.9 = -log[H+]
[H+] = 10^-2.9 = 0.00126 M
The Californian red wine (pH 3.5) has a hydrogen concentration of 0.00032M
The italian white wine (pH 2.9) has a hydrogen concentration of 0.00126 M
The italian white wine has a higher concentration of hydrogen ions, what means it's more acid than the californian red wine.
The answer to your question is an Egg
Answer:
By definition, there are 6.022×1023 such molecules, or NA such molecules in ONE mole of water. And thus in such a quantity there are NA oxygen atoms, and 2×NA hydrogen atoms...and the mass associated with this numerical quantity of water molecules is approx. 18⋅g ...
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. (Put it in ur own words if u can) !!
<em>Answer:</em>
- Such a alkane has only one ring that is cyclooctane.
<em>Explanation:</em>
- The general formula of alkane is CnH2n+2. Such general formula is applicable for only open chain alkane.
- When alkane form ring, then this formula does not remain valid.
- The general formula of Cycloalkane is CnH2n.
As in this case, there are 8-carbon and 16-hydrogen that is according to above cycloalkane formula.
