Answer:
D. -1882J
Explanation:
We can solve the energy released in a chemical reaction in an aqueous medium using the equation:
Q = -m*C*ΔT
<em>Where Q is energy (In J),</em>
<em>m is mass of water (45.00g)</em>
<em>C is specific heat of water (4.184J/g°C)</em>
<em>And ΔT is change in temperature (25.00°C - 15.00°C = 10.00°C)</em>
<em />
Replacing:
Q = -45.00*4.184J/g°C*10.00°C
Q = -1882J
Right answer is:
<h3>D. -1882J</h3>

Answer: Ecell = -0.110volt
Explanation:
Zn--->Zn^+2 + 2e^-.........(1) oxidation
Cu^2+ 2e^- --->Cu........(2)reduction
Zn + Cu^2+ ----> Cu + Zn^+2 (overall
For an electrochemical cell, the reduction potential set up is given by
E(cell) = E(cathode) - E(anode)
E(cell) = E(oxidation) - E(reduction)
E(cathode) = E(oxidation)
E(anode) = E(reduction)
Given that
E(oxidation) = -0.763v
E(reduction) = +0.337v
E(cell) = -0.763 - (+0.337)
E(cell) = -0.763- 0.337
E(cell) = -0.110volt
Answer:
<u>False</u>
Explanation:
- The carbon cycle is a process which involves the flow of carbon through all of living things and life forms on Earth. The carbon cycle span over two segments: long-term and short-term, allowing for regulation of atmospheric carbon dioxide.
- While the short term segment deals with Earth forms that are more 'fleeting' like water nd air, the long-term affects the rock which take centuries to process through completely.
- In the short-term reservoir, carbon is stored in the atmosphere, oceans and biosphere with the ocean containing the largest amount of carbon. The biggest player and regulator of atmospheric carbon however is the ocean, not the biosphere. It is what links the long-term segment reserves to the short-term because carbon dioxide is removed from the atmosphere and converted to fossil fuels and rocks which are components of the long-term reserves.
I hope this explanation was clear and comprehensive.
