Answer:
8.17 × 10^-7
Explanation:
You would divide 3 + 10^8 with 3.67 ×10^14, Which gives you the number 8.174369 = 8.17 :)
Answer:
<em>249 kJ</em>
Explanation:
To obtain the energy change of the reaction:
H₂O → H₂ + ¹/₂ O₂
It is necessary to obtain the difference between bond energy of the products and bond energy of the reactant, thus:
Energy of products:
1 mol of H-H bond × 436 kJ/mol = 436 kJ
¹/₂ mol of O=O bond × 498 kJ/mol = 249 kJ
Energy of reactant:
2 mol of H-O bond × 467 kJ/mol = 934 kJ
Energy change of the reaction is:
934 kJ - (436 kJ + 249 kJ) = <em>249 kJ</em>

Multiply the weight of the object by the distance it traveled to find the amount of work output. For the example: 10 lbs. x 1 foot = 10 foot-pounds. Find the work efficiency by dividing the work output by the work input and multiplying by 100.
Answer:
The chemical reactions in which oxidation and reduction takes place are called redox reaction.
Explanation:
CH4. + O2----> CO2. + H2O
The other answer was very rude. Anyways I think the answer is Salt. Also if you view my profile don't mind the age I am actually 13. e.e
