If the bonds of the product store 27 KJ more energy than the bonds of the reactants, It means the surroundings absorb 27 kj of energy from the reaction system Hence, Option (D) is the correct answer
<h3>What is the Exothermic reaction ?</h3>
An exothermic process releases heat, causing the temperature of the immediate surroundings to rise.
The bonds of the product store 27 KJ more energy than the bonds of the reactants, It means that energy has been absorbed by the surrounding as the product formed is more stable due to more stronger bond
This can be inferred from more stored energy with in the bonds and Thus, It is a exothermic reaction.Hence, Option (D) is the correct answer

Answer:
The correct alternative is "Option a".
Explanation:
Oxidation has become a mechanism whereby the physicochemical properties transform attributed to the formation of O₂.
- The connection involving magnesium as well as O₂ requires the oxidation of the component named magnesium.
- Even before exposed to the air, silicon is oxidized as well as generates silicon dioxide.
Other possibilities are not connected to the scenario in question. So Choice A is the best option.
This is a incomplete question. The complete question is:
It takes 348 kJ/mol to break a carbon-carbon single bond. Calculate the maximum wavelength of light for which a carbon-carbon single bond could be broken by absorbing a single photon. Round your answer to correct number of significant digits
Answer: 344 nm
Explanation:
E= energy = 348kJ= 348000 J (1kJ=1000J)
N = avogadro's number = 
h = Planck's constant = 
c = speed of light = 
Thus the maximum wavelength of light for which a carbon-carbon single bond could be broken by absorbing a single photon is 344 nm
Answer:
32
Explanation:
0.56dm of gas has 0.8g
22.4dm of gas Z has a mass of 22.4/0.56X0.8
the relative molecular mass of gas Z is 32
