The energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
Conversion factor : molar mass/molecular weight
Mass of H₂O produced = 72 g
<h3>Further explanation</h3>
Given
Reaction
2H2 + O2- 2H20
8 grams of H2
Required
Conversion factors
Solution
We can use the molar mass of the components and the mole ratio as conversion factors for the above equation
mol H₂ (MW = 2 g/mol) :
From the equation, mol ratio of H₂ : H₂O = 2 : 2, so mol H₂O = 4 mol
mass H₂O(MW = 18 g/mol) :
mass = mol x MW
mass = 4 x 18
mass = 72 g
I believe it is newton`s first law of motion
Answer:
The correct answer is: <em>There must be potential energy in the bonds due to its particles position.</em>
Explanation:
Potential energy is a kind of energy which is stored in an object due to its position or configuration. For example, if there is a ball in the fifth floor of a building, it has a determined potential energy which is converted to kinetic energy when the ball fall down. The same is in the case of the chemical bonds: the particles or atoms have potential energy related to their relative positions in the system. In fact, chemical energy is considered a form of potential energy (stored in chemical bonds).
Answer:
In order to take steps by humans for controlling the change in climate.
Explanation:
It is important that scientist find out the change which occurs in the climate with the passage of time by performing experiments and also repeat the experiments in order to verify their findings. Due to these experiments, scientists also find out the reasons behind of climate change which enable us to take steps in preventing the change that occurs in the environment. it is also important for scientists to be able to explain how they know that climate has changed over time in order to explain that he is not assuming or making predictions, he has to provide evidence for his statement which is only be possible through experiments.
