The Equation given in statement is as follow,
<span> 2 C</span>₂H₂<span> + O</span>₂<span> → 4 CO</span>₂<span> + H</span>₂<span>O
According to equation,
Carbon atoms on reactant side are 4 in number, and that on product side are also 4 in number. SO, carbon atoms are balanced.
Hydrogen atoms on reactant side are 4, and on product side are 2. Means Hydrogen atoms are not balance. So, to balance them multiply H</span>₂O with 2. So,
2 C₂H₂ + O₂ → 4 CO₂ + 2 H₂O
Now, calculate number of Oxygen atoms on both sides. There are 2 Oxygen atoms on reactant side and 10 Oxygen atoms on product side. So, to balance them multiply O₂ on reactant side with 5. So,
2 C₂H₂ + 5 O₂ → 4 CO₂ + 2 H₂O
Above Equation is balanced.
Lead (Pb) has the electron configuration [xe] 6s2 4f14 5d10 6p2.
<h3><u>
What is electronic configuration ?</u></h3>
A neutral element's total number of electrons is represented by its electronic configuration. To get the total number of electrons in an atom, we sum all the superscripts.
As the last electron enters the p orbital, the provided element is a p block element. Xenon, a noble gas with 54 electrons, is the closest.
According to Afbau's rule, the electrons are filled in the sequence of increasing energies, and the electronic configuration in terms of the noble gs configuration is as follows:
Total electrons = 54 + 2 + 14 + 10 + 2 = 82
Lead is the element with the symbol whose atomic number is 82 since it contains 82 electrons.

Calcite can be either dissolved by groundwater or precipitated by groundwater, depending on several factors including the water temperature, pH, and dissolved ion concentrations. Although calcite is fairly insoluble in cold water, acidity can cause dissolution of calcite and release of carbon dioxide gas.
