The science is based on the whole data you can get and make adjustments only from data. While pseudoscience based on part of the data and get the results that they want.
Answer:
c. CH₃COO⁻
Explanation:
The task is not very clear but I think this is the original question.
<em>Identify the conjugate base of CH₃COOH in the reaction:
</em>
<em>CH₃COOH + HSO₄⁻ ⇄ H₂SO₄ + CH₃COO⁻
</em>
<em>a. HSO₄⁻
</em>
<em>b. SO₄²⁻
</em>
<em>c. CH₃COO⁻</em>
<em>d. H₂SO₄</em>
<em>e. OH⁻</em>
Let's consider the following reaction
CH₃COOH + HSO₄⁻ ⇄ H₂SO₄ + CH₃COO⁻
According to the Bronsted-Lowry acid-base theory, an acid is a species that donates H⁺ and a base is a species that accepts H⁺.
CH₃COOH is an acid because it donates H⁺ to HSO₄⁻, whereas CH₃COO⁻ is its conjugate base, because it accepts H⁺ from H₂SO₄ to form CH₃COOH.
Another acid-base pair is H₂SO₄/HSO₄⁻
They're the Isotopes of nitrogen atoms.
the atoms of the same kind of element, which has a same number of protons but a different number of neutrons, they're referred as the Isotopes of the element.
Not all elements has Isotopes, and each element's Isotopes are different. Some may be unstable, some may be stable.
Isotopes of the element must have the same number of protons, as proton is never changed in an element, it's like an ID number. Only the number of neutron is different, and not the electron numbers too, or else it'll become an ion. When we talk about Isotopes of an element, we usually say it in form of the element name, then followed by the mass number (proton + neutron), therefore, for example in the question, nitrogen has a proton number of 7, so the isotope with 7 neutrons is regarded as nitrogen-14.
