Is it possible for the instantaneous speed to be greater than the average speed? Explain.

Chemistry
1 answer:
USPshnik [31]3 years ago
7 0

Answer:

The mean value theorem tells us the average velocity must be between the minimum velocity and the maximum velocity. The only way it can be either the minimum or the maximum is if velocity is constant. So of course instantaneous velocity can be greater and can be less.

2. How is the layer of iridium used to tell the relative age of different rock strata and fossils?
Fantom [35]

Answer and Explanation:deposition has been occurring on earth for a very long time. as time goes by, more deposits form layers on the earth, including the remains of animals and plants that would later become fossils, burying the previous deposits in another layer of newer deposits. therefore it follows that layers which are found deeper are older than those found in layers near the surface....

When methane, CH4, is combusted, it produces carbon dioxide, CO₂, according to the unbalanced equation: CH4 +0₂ - CO₂ + H₂O.
nevsk [136]

The balanced equation will be CH_4 + 2O_2 --- > CO_2 + 2H_2O

<h3>Stoichiometric problems</h3>

The balanced equation of the reaction would be as follows:

CH_4 + 2O_2 --- > CO_2 + 2H_2O

The mole ratio of methane to carbon dioxide is 1:1.

10 grams of methane will give 10/16 = 0.625 moles

0.625 moles of carbon dioxide would give 0.625 x 44.01 = 27.506 grams.

Thus, 10 grams of methane will produce approximately 27 grams of carbon dioxide stoichiometrically.

The reaction obeys the law of conservation of mass because the atoms of all the elements before and after the reaction are balanced.
