Explanation:
Different heating process affect the microstructure of the steel in different ways. Thus, imparting different properties to the steel. For example, annealing is done is done to impart softness to steel, hardening is done to hardened the steel( eg: carburizing, nitriding, cyaniding) whereas tempering is done to improve the ductility of the steel.
Steel mainly contains iron and carbon. This percentage of carbon and iron decides the property of the steel. It is the % of carbon which is altered in different heating process that to obtained the desire microstructure in steel.
32 grams of sulfur will contain 6.022 X 1023 sulfur atoms.
Answer:
d. The air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down.
Explanation:

From the given chemical formula or equation, it can be seen that for every molecule of the given chemical, there are 2 moles of NH4+ ions. Thus, to calculate for the concentration of the ion in the solution, we multiply 0.30M by 2 giving as an answer of 0.60M.
