Answer: 13.31 moles.
Explanation: So take 452 grams of Argon and multiply by the molar mass of Argon. Your units will cancel out, leaving you with moles of Argon.
Answer:
To know if a reaction/experiment is exothermic or endothermic depends on the temperatures of the two liquids you are trying to mix. First before mixing your liquids take the temperature of both of them and write it down. then mix both liquids together to get your reaction and take the temperature of both mixed together. write it down. Did the temperature of your liquids increase or decrease? this question will determine weather the reaction was endothermic or exothermic. Endothermic meaning the temperature got cooler and Exothermic meaning the temperature got hotter/warmer
EX. | starting temperature- 72 F | ending temperature- 82 F | Exothermic
EX 2. | starting temperature- 72 F | ending temperature- 69 F | Endothermic
Explanation: I hope this helped you :)
B
A mixture can be separated by a physical means because there is no chemical bond between the constituents
Its used to increase intestinal absorbance of calcium, magnesium etc
