Copper is a good conductor of heat. This means that if you heat one end of a piece of copper, the other end will quickly reach the same temperature. Most metals are pretty good conductors; however, apart from silver, copper is the best.
Aluminum is an excellent heat and electricity conductor and in relation to its weight is almost twice as good a conductor as copper.
Glass is a very poor heat conductor. It has one of the lowest possible heat conduction a solid (without air trapped in it) can possibly have, this is mostly due to its lack of ordered crystal structure. Since it's an insulator, the electronic contribution to the thermal conductivity is very small.
Metals and stone are considered good conductors since they can speedily transfer heat, whereas materials like wood, paper, air, and cloth are poor conductors of heat. ... These include copper (92), iron (11), water (0.12), and wood (0.03).
Wood and Glass do not conduct heat well, aluminum is the best for him to choose because
aluminum conducted heat the fastest at an average of 14 seconds. ... Aluminum has the ability to absorb heat faster than copper, and when removed from the heat source, will cool faster because it is less dense than copper
I'm almost certain that it is Magnesium Nitrate

Answer:
1.4952 grams of sodium bicarbonate she would need to ingest to neutralize this much HCl.
Explanation:
Moles of hydrochloric acid = n
Volume of hydrochloric acid solution = 200.0 mL = 0.200 L
Molarity of the hydrochloric acid = 0.089 M
of HCL
According to reaction, 1 mole of HCl is neutralized by 1 mole of sodium bicarbonate.
Then 0.0178 moles of HCl wil be neutralized by :
of sodium bicarbonate
Mass of 0.0178 moles of sodium bicarbonate:
0.0178 mol × 72 g/mol = 1.4952 g
1.4952 grams of sodium bicarbonate she would need to ingest to neutralize this much HCl.
