Answer:
Callie expect 600 molecules of CO2 to have been released as a waste during the same amount of time.
Explanation:
During cellular respiration 1 molecule of glucose undergoes oxidation to form 6 molecules of CO2 as a waste product.
According to the question callie determined that the germinating corn seed had utilized 100 molecules of glucose.
So 100 molecules of glucose will release 100×6=600 molecules of CO2 as a waste product.
Question:
A student weighed an empty graduated cylinder. It weighed 35.86 g. She then carefully added water to the graduated cylinder until it reached the 7.5 mL mark. When she weighed the graduated cylinder again, this time with the 7.5 mL of water in it, it weighed 43.18 g. What was this student's experimental density of water?
Answer:
0.976 g/mL
Explanation:
Weight of empty cylinder = 35.86g
Volume of water = 7.5mL
Weight of cylinder + water = 43.18g
Experimental density = ?
Density of water = Mass of water / volume of water
Mass of water = (Weight of cylinder + water) - Weight of empty cylinder
Mass of water = 43.18 - 35.86 = 7.32g
Density = 7.32 / 7.5 = 0.976 g/mL
The correct answer is C. Compounds have different properties than their component elements. When compounds are formed, they undergo change resulting to changes in the properties they exhibit. It will have its new set of properties different from the elements.
Answer: D. transverse
Explanation:
Light is a transverse wave, while sound is a longitudinal wave.
