Ice has the lowest energy; liquid water has “medium” energy; and water vapor has the highest energy.
<h2>Let us explain about green house gases</h2>
Explanation:
Green house effect
It can be explained as :
- The sun emit radiations that consist of infra red rays , ultra violet rays and visible light .
- The infra red rays (responsible for heating ) when come from sun , it travels through atmosphere and reaches earth surface .
- On striking the earth surface , it gets reflected and reflected infra red ray has greater wavelength .
- Then this reflected rays moves back through atmosphere .
- On doing so , they encounter certain gas molecules like carbon dioxide , methane etc .
- This gases absorb these rays and do not let them to escape through them .
- As a result, they get trapped .
- As we have already mention that they cause heating effect , due to this property they raise the temperature of atmosphere leading global warming .
Explanation:
<em>An</em><em> </em><em>independent</em><em> </em><em>variable</em><em> </em><em>is</em><em> </em><em>defines</em><em> </em><em>as</em><em> </em><em>the</em><em> </em><em>variable</em><em> </em><em>that</em><em> </em><em>is</em><em> </em><em>changed</em><em> </em><em>or</em><em> </em><em>controlled</em><em> </em><em>in</em><em> </em><em>a</em><em> </em><em>scientific</em><em> </em><em>experiment</em><em>. </em>
This statement is true. The rate of the reaction is measured by how fast a reactant is used up, or how fast a product is formed. This all tie's into the usage of energy.
Answer: There are 0.00269 moles of acetic acid in buffer.
Explanation:
To calculate the number of moles for given molarity, we use the equation:
.....(1)
Molarity of acetic acid solution = 0.0880 M
Volume of solution = 30.6 mL
Putting values in equation 1, we get:
Thus there are 0.00269 moles of acetic acid in buffer.
