Answer:1) Volume of required is 55.98 mL.
2) 0.62577 grams of is produced.
Explanation:
1) Molarity of
Volume of
Molarity of
Volume of
According to reaction, 1 mole of reacts with 3 mole of , then, 0.0041985 moles of will react with:
moles of that is 0.0125955 moles.
Volume of required is 55.98 mL.
2)
Number of moles of
According to reaction, 3 moles of gives 1 mole of , then 0.004485 moles of will give: moles of that is 0.001495 moles.
Mass of =
Moles of × Molar Mass of
= 0.001495 moles × 418.58 g/mol = 0.62577 g
0.62577 grams of is produced.
Answer:
→A space heater warms a room⇒By converting electrical energy into heat energy.
→You eat dinner⇒Our body uses chemical energy to break down the food
→A radio plays⇒By converting electrical energy into sound energy in an electric radio. And by converting chemical energy into sound energy in a radio which runs with a cell.
Explanation:
The solubility of a substance is usually expressed as the mass of a substance, in g, that will dissolve in a fixed amount of solvent (liquid), usually 100 g, at a given temperature.
Some material from meteors lingers in the mesosphere, causing this layer to have a relatively high concentration of iron and other metal atoms. Very strange, high altitude clouds called "noctilucent clouds" or "polar mesospheric clouds" sometime form in the mesosphere near the poles.
I really hope this helps! I wish you the best of luck!
