Answer: The sentence given is false.
Explanation:
The question requires us to determine if the sentence given by the question ("pH can only be between 1 and 14") is true or false.
The pH value is matematically defined as:
where [H+] is the concentration of H+ ions in solution.
If the concentration of H+ is too high, such as in an acid battery, the pH of a solution can reach 0. However, its value cannot be negative. Therefore, we can say that the pH scale ranges from 0 (very acidic medium) to 14 (very alkaline medium).
Considering the sentence given, we can say that it is false.
B) 40%
The balanced equation indicates that for every 3 moles of H2 used, 2 moles of NH3 will be produced. So the reaction if it had 100% yield would produce (2.00 / 3) * 2 = 1.333333333 moles of NH3. But only 0.54 moles were produced. So the percent yield is 0.54 / 1.3333 = 0.405 = 40.5%. This is a close enough match to option "b" to be considered correct.
⁷⁰₂₉Cu
Explanation:
Copper-70 isotope in nuclide form.
A nuclide is designated as: ₙᵇX
Where X is the symbol of the atom
b is the mass number of the atom
n is the atomic number
Mass number is the number of protons and neutrons in an atom. These particles makes up the bulk of the mass of an atom.
Atomic number is the number of protons in an atom. For neutral atom, it is the same as the number of electrons.
To write Copper-70 in nuclide format:
Symbol of Copper is Cu
Mass number is 70
Atomic number from periodic table is 29
⁷⁰₂₉Cu

The name given to an ion that has lost electrons is cation. Details about cations can be found below.
<h3>What is a cation?</h3>
A cation is a positively charged ion i.e. the one that would be attracted to the cathode in an electrolytic procedure.
Generally, an ion is an electrically charged atom. An ion can either be positively charged or negatively charged. The latter is called an anion while the former is called a cation.
A cation is formed when an atom loses electrons to become positively charged while an anion is formed when an atom accepts electrons to become negatively charged.
Therefore, it can be said that the name given to an ion that has lost electrons is cation.
