<h3>What is pH?</h3>
The term pH, which originally stood for "potential of hydrogen" (or "power of hydrogen"), is used in chemistry to describe how acidic or basic an aqueous solution is. Lower pH values are summarized for acidic solutions (solutions with higher H+ ion concentrations) than for basic or alkaline solutions.
The pH scale is inversely indicates to the concentration of hydrogen ions in the solution and is logarithmic.
⇒pH = -log()
Acidic solutions are those with a pH below 7, and basic solutions are those with a pH above 7, at a temperature of 25 °C (77 °F). At this temperature, solutions with a pH of 7 are neutral (e.g. pure water). The pH neutrality relies on temperature, falling below 7 if the temperature rises above 25 °C.

<span>Nuclear reactions have two main types: fission reactions and fusion reactions. When two light nuclei are joined to create a heavier and more stable nucleus, this process is called the fusion reaction. In the fission reaction, the heavy nucleus split into two nuclei with a smaller mass number. In other words, fission is splitting of atoms although not all atoms undergo fission, only few went through normal circumstances (that is a fact). </span>
Answer:
when they form a bond, Atom B has higher electronegativity than atom A.
Explanation:
Electronegativity is the tendency of an atom in a bond pair to attract the shared pair of electron towards itself.
Covalent bond is the bond which is formed with the sharing of the electrons between the two atoms which are taking part in the bond. It is generally formed between the atoms with similar electronegativity values.
It is the bond which is generally occurs within non metals as they share electrons to complete their octet.
The difference in the electronegativity values of the atoms involving in a covalent bond must not exceed the value of 1.7 .
The electrons in case of atom B are close to the nucleus and in case of atom N are far from the nucleus. Thus, when they form a bond, Atom B has higher electronegativity than atom A.
Answer:
the last one is the correct anwser
Answer:
Explanation:
usually, the first step is to calculate the moles but since that is already given in the question we can move onto the next step
<em><u>least molar ratio:</u></em>
<em>Cu = </em> = 3
P = = 1
thus, empirical formula =
