<span>Welding in confined spaces or on stainless steel generates (B) Hexavalent Chromium a very toxic chemical. Hexavalent chromium are chemical compounds that has a chromium with an oxidation state of +6. It is commonly used in textile dyes and wood preservation to avoid corrosion and conversion coatings.</span>
Oxidation: a chemical change resulting form a reaction with oxygen
Endothermic:a reaction that takes in energy
Exothermic: a reaction that releases energy
Decomposition:chemical change whereby a molecule breaks down into simpler moles clues or elements

Explanation:
here's the answer to your question about
Answer:
The solubility of a substance in water increases as the temperature rises, especially for gases.
The solubility of a substance in water with temperature generally increases for ionic solids.
Explanation:
Solid substances dissolved in liquid water, the solubility increases with temperature. Gases tend to naturally have high entropy or kinetic energy than solid substances so the same still applies.
This phenomenon is due to the increase in kinetic energy acquired by the particles of the solid at higher temperatures which allows the solvent molecules to effectively break apart the solute molecules that are held together by intermolecular attractions
