Answer: Are there options? I think the answer is continents, but I don't really understand the question. Is continents an option?
Explanation:
Exothermic<span>- the word describes a process that releases </span>energy<span> in the form of heat. Forming a chemical bond releases </span>energy<span> and therefore is an </span>exothermic<span> process. </span>Exothermic<span>reactions usually feel hot because it is giving heat to you. </span>Endothermic<span> - a process or reaction that absorbs </span>energy<span> in the form of heat.</span>
Meteoroids are smaller than comets and asteroids.
Limestone is calcium carbonate Ca(Co3) it's dissociation equation is as follows:
Ca(CO3) <----> Ca+2 + CO3-2
but the solubility is very small
in the presence of acid by LeChatlier's Principle you can shift to the right by adding acid
H+ + CO3-2 <-----> H+CO3- (the bicarbonate ion which is really soluble)
The system will pull more and more limestone out into solution as acid is added and neutralize the acid coming from the rain.
The solution would be like
this for this specific problem:
<span>25.0 g CCl4 x (1 mole CCl4
/ 153.8 g CCl4) = 0.163 moles CCl4
</span>(29.82 kJ / mole)(0.163 moles) = 4.86 kJ
total heat = 1.11 kJ + 4.86 kJ = 5.97 kJ
<span>I hope this helps and if you have
any further questions, please don’t hesitate to ask again. </span>
