Answer:
Properties
Explanation:
Mendeleev realized that the physical and chemical properties of elements were related to their atomic mass in a 'periodic' way, and arranged them so that groups of elements with similar properties fell into vertical columns in his table.
Question A is more testable through a scientific experiment because you have a specific thing you are trying to find out, "which gelatin takes longer to set".
Answer:
Aerobic Respiration
It can be found in the cytoplasm and the mitochondria.
Glucose breaks down into carbon dioxide and water.
Anaerobic Respiration
It can be found only in the cytoplasmic.
Glucose breaks down into ethyl alcohol, carbon dioxide and energy
Different boiling point.
Because in distillation the substance with lower boiling point is evaporated, leaving the other material(s).
Answer:
[MCHM] = 7.52 M
Explanation:
This all about unit conversion
1 feet = 0.3048 meters
1 yard = 0.9144 meters
7.60 feet . 0.3048 = 2.31 meters deep
100 yd . 0.9144 meters = 91.44 meters long and 91.44 meters wide
In the river we have a volume of:
2.31 m . 91.44m . 91.44m = 19314.5 m³
1 dm³ = 1 L
1 dm³ = 0.001 m³
19314.5 m³ / 0.001 m³ = 19314542 L (The final volume of the river)
3.785 L = 1 gallon
In 19314542 L, we have (19314542 / 3.785) = 5102917 gallons
1 gallon = 128 oz
5102917 gallons . 128 = 653173376 oz
1 oz = 28.3495 g
653173376 oz . 28.495 = 1.86x10¹⁰ grams
Molar mass MCHM = 128 g/m
Moles of MCHM = 1.86x10¹⁰ grams / 128 g/m = 145312500 moles
Molarity = mol /L → 145312500 moles / 19314542 L = 7.52 M
