Nucleosynthesis began when _____ and ended when _____
lutik1710 [3]
<h2>Nucleosynthesis.</h2>

Explanation:

A. the Big Bang occurred; the Big Crunch occurred

Nucleosynthesis is the process by which new atomic nucleus are formed from pre-existing protons and neutrons.

According to cosmic theories, the nucleosythesis began one minute after the occurrence of Big bang and will end with the big Crunch.

The Big bang theory describes all the processes by which the universe came into existence while the big crunch theory explains how universe will come to an end.  A

Which of the following atoms would gain two electrons to fill its valence energy level?
Harlamova29_29 [7]

The atom that would gain two electrons to fill its valence energy level is S(sulfur)

This is because s (sulfur) is in atomic number 16 with 2.8.6 of [Ne] 3s^2 2p^4 electronic configuration. This implies that sulfur has 6 valence electron and therefore it require two electron to fill its valence energy level and obtain 18 rule electrons.

Complete the charge balance equation for an aqueous solution of h2co3 that ionizes to hco−3 and co2−3.
Zielflug [23.3K]

The charge balance equation for an aqueous solution of H₂CO₃ that ionizes to HCO₃⁻ and CO₃⁻² is [HCO₃⁻] =  2[CO₃⁻²] + [H⁺] + [OH⁻]

<h3>What is Balanced Chemical Equation ?</h3>

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

The equation for aqueous solution of H₂CO₃ is

H₂CO₃ → H₂O + CO₂

The charge balance equation is

[HCO₃⁻] =  2[CO₃⁻²] + [H⁺] + [OH⁻]

Thus from the above conclusion we can say that The charge balance equation for an aqueous solution of H₂CO₃ that ionizes to HCO₃⁻ and CO₃⁻² is [HCO₃⁻] =  2[CO₃⁻²] + [H⁺] + [OH⁻]

In the figure below, two nonpolar molecules are interacting.Which interaction would most likely cause these molecules to repel e
Fed [463]
Two non-polar molecules are most likely to interact by
induced dipole-induced dipole interaction.

Non-polar substances do not have a permanently established charge distribution due to similar electron affinities of the atoms that are present. Moreover, due to the absence of a polar hydrogen, they cannot exhibit hydrogen bonding. They interact with one another by induced dipole-induced dipole interactions which arise from the molecules of the substances coming into close vicinity of one another.
