One conclusion from Rutherford's experiment that greatly contradicted Thompson's experiment is that 'atoms are mostly empty space, with positively charged nucleus'. While Thompson concluded that there are negatively charged particles as part of the internal structure of the atoms.
<u>Answer:</u> The hydrogen ion concentration in apple juice is
<u>Explanation:</u>
pH is defined as negative logarithm of hydrogen ion concentration. It is basically defined as the power of hydrogen ions in a solution.
Mathematically,
We are given:
Putting values in above equation, we get:
Hence, the hydrogen ion concentration in apple juice is
Answer:
Sour taste, low pH, and dissolves metals
Explanation:
Acids have a pH below 7.0. Acids turn litmus paper red as they have pH below 7.0. Bases on the other hand have pH above 7.0. Water has a neutral pH of 7.0.
Acids have a sour taste. For example citric acids found in lemons make it sour. Vinegar has acetic acid which makes it sour.
Acids dissolve metals to form salts and hydrogen gas
2HCl + Zn → ZnCl₂ + H₂
Answer:
The valence shell (the 3s and 3p sublevels) contains six electrons, but it needs eight to become stable. Think of the octet rule. Therefore a sulfur atom will gain two electrons to form the sulfide anion with a charge of 2− , with the symbol S2− .
