The pH of a neutral aqueous solution at 37°C is 6.8.
<h3>What is Kw? </h3>
Kw is defined as the dissociation, which is also known as self-ionization, constant of water. this is an equilibrium constant, and its expression is:
Kw = [OH⁻] . [H₃O⁺]
Neutral pH determines that the concentrations of OH⁻ and H₃O⁺ are equal.
<h3>Calculation</h3>
Let us suppose concentration of OH and H₃O⁺ is x, to calculate it:
Kw =[OH⁻] . [H₃O⁺] = x²
x² = 2.4 × 10⁻¹⁴ M²
x = 1.5919 × 10⁻⁷ M
Hence, the concentration of OH and H₃O⁺ (x) = [H₃O⁺] = [OH⁻] = 1.5919×10⁻⁷ M
pH = -log[H₃O⁺] = -log( 1.5919×10⁻⁷ M)
pH = 6.8
Thus, we find that the pH of a neutral aqueous solution at 37 °c (which is the normal human body temperature) is 6.8.

#SPJ4
120.38 g/mol is the answer
Gases in which the molecules that make it up naturally consist of two atoms of the same type.
Answer:
Explanation:
A tetrahedral carbon is__sp³__hybridized while a linear carbon is__sp___hybridized. Two different compounds that have the same molecular formula are known as___isomers____. Pi (π) bonds are generally_weaker (because they overlapped side ways)___than sigma (sigma) bonds. Hybridization is the combination of two or more__atomic ____orbitals to form the same number of__hybrid (combined s and p)__orbitals, each having the same shape and energy. A_pi (π)____bond is formed by side-by-side overlap of two p orbitals. The_electronegativity___is a measure of an atom's attraction for electrons in a bond and indicates how much a particular atom ''wants" electrons. Two Lewis structures that have the same atomic placement and a structure but a different arrangement of pi electrons are called_Resonance structure____. All single bonds are___sigma__bonds.
