Answer: Uranium enrichment. Uranium is used to fuel nuclear reactors; however, uranium must be enriched before it can be used as fuel. Enriching uranium increases the amount of uranium-235 (U235) that can sustain the nuclear reaction needed to release energy and produce electricity at a nuclear power plant.
Options:
- NaOH(aq)
- NaOH(l)
- N2(g)
- NO(g)
Answer: <em>NaOH (aq)</em>
Explanation:
Defining state terminologies, '<em>aq' </em>means aqueous, meaning the analyte is in solution, as opposed to gaseous (g), or liquid (l).
Pressure - Force per unit area

Answer:
2 Answers. Most transition metals have 2 valence electrons. Valence electrons are the sum total of all the electrons in the highest energy level (principal quantum number n). Most transition metals have an electron configuration that is ns2(n−1)d , so those ns2 electrons are the valence electrons.
