Answer:
Potential energy is the energy stored within an object, due to the object's position, arrangement or state. Potential energy is one of the two main forms of energy, along with kinetic energy.
Explanation:
Answer:
185.1 m/s
Explanation:
The average speed of an object is a scalar quantity telling us how fast is the object moving over a certain distance.
This quantity is calculated as
where
d is the distance covered by the object
t is the time elapsed
v is the average speed
In this problem we have:
d = 1500.0 m is the distance covered by Ken
t = 8.1018 s is the time taken
Substituting into the formula, we find the average speed:
Answer:
The answer to your question is below
Explanation:
Organic chemistry studies the compounds that have carbon, hydrogen, oxygen and other elements in their structure.
Carbohydrates are biomolecules that are composed of carbon, hydrogen, and oxygen that is why they are studied by organic chemistry.
Other biomolecules that are also studied by organic chemistry are Proteins, Lipids, and Vitamins.
1. 9.36 moles S
2. 0.213 moles Al
<h3>Further explanation</h3>
Given
Reaction
2Al+3S⇒Al₂S₃
Required
moles of S
moles of Al
Solution
The reaction coefficient in a chemical equation shows the mole ratio of the compounds involved in the reaction (reactants or products)
From equation, mol ratio of Al₂S₃ : S = 1 : 3, so mol S :
= 3/1 x mol Al₂S₃
= 3/1 x 3.12
= 9.36 moles S
From equation, mol ratio of Al : S = 2 : 3, so mol Al :
= 2/3 x mol S
= 2/3 x 0.32
= 0.213 moles Al
Answer:
The answer to your question is Temperature 2 = 244.5°K
Explanation:
Data
Pressure 1 = 3.90 atm
temperature 1 = 298°K
Pressure 2 = 3.20 atm
temperature 2 = ?
Process
1.- Use the Gay-Lussac law to solve this problem
Pressure 1/Temperature 1 = Pressure 2/Temperature 2
-Solve for Temperature 2
Temperature 2 = Temperature 1 x Pressure 2 / Pressure 1
-Substitution
Temperature 2 = 298 x 3.20 / 3.90
-Simplification
Temperature 2 = 953.6 / 3.90
-Result
Temperature 2 = 244.5°K
