Answer: 1. 3.914 × ^10-4 | 2. 4.781 × ^10-1
Explanation:
Answer:
74 g/mol
Explanation:
Using a periodic table, we can determine the molar mass by adding together 1 Ca, 2 O, and 2 H. This turns out to be approximately (40+32+2) = 74 g/mol
Answer:Mass of Potassium chloride =1.762g
Explanation:
Mass of empty beaker = 23.100 g
Mass of beaker with Potassium chloride = 24.862g
Mass of Potassium chloride = Final weight - initial weight = Mass of beaker with Potassium chloride - Mass of empty beaker = 24.862-23.100 = 1.762g
The correct answer of the given question above would be option B. Water is composed of the same elements as carbon monoxide, but their properties compare because they have different properties due to the different arrangement of atoms. Hope this answer helps.
Answer:
-100 K
Explanation:
<em>Kinetic energy is related to temperature.</em> The molecules in water will move faster in warmer temperatures than in colder ones.
100 K is equal to -279.67°F (-173.15°C). So 100 K would have the lowest average kinetic energy.
