nlinux.org: cellular respiration is the process through which chemical energy in organic molecules such as carbohydprices is released by stepwise oxidative process, catalyzed by enzymes and made accessible in the for of ATP. It have the right to be divided as
aerobic respiration - synthesize of ATP from respiratory substrates in the presence of molecular oxygen
anaerobic respiration - breaking down of glucose in the lack of molecular oxygen which is regulated by enzymes of the cells occuring in cytosol.
the nlinux.org i offered over quite meet the question unless it is an essay question. if it is an essay it needs even more explaination

What is the pH of an acidic solution?
The nlinux.org is A, between 0 and 7.In a pH range from 0 to 14, we deserve to teams these numbers into acidic, neutral, and alkaline. 7 is the neutral pH value, therefore, 0-7 is always acidic, and 7-14 is alkaline.The smaller sized the number is, the even more acidic the solution will be. This uses same in alkalis, the larger the pH value is, the even more alkaline the solution is.We have the right to measure the pH of solution via many techniques, the simplest method encompass using a pH paper, even more advanced and precise methods has utilizing a pH meter.

In a synthesis experiment you attain a sample of product on which you perform a melting suggest determicountry and also discover a melting allude
nlinux.org:1) the sample is more than likely impure
Explanation:this is because pure samples have sharp melting points. If the sample is expect to be benzoic acid, and also the melting suggest of pure benzoic acid is 122.3oC, then it is definitely impure. The visibility of Impurities lowers melting points of purr substances with melting points depression. So the sample is impure benzoic acid. You also have to calibrate the thermometer prior to taking measurements.

Given the reactions, X ( s ) + 1 2 O 2 ( g ) ⟶ XO ( s ) Δ H = − 607.3 kJ XCO 3 ( s ) ⟶ XO ( s ) + CO 2 ( g ) Δ H = + 356.9 kJ wh
The nlinux.org to your question is ΔH = -964.2 kJ
Reactivity 1 X + 12O₂ ⇒ XO ΔH = -607.3 kJ
Reaction 2 XCO₃ ⇒ XO + CO₂ ΔH = 356.9 kJ
ΔH for Reaction 3 X + 12O₂ + CO₂ ⇒ XCO₃
1.- Write the Reaction 1 the very same
2.- Invert the order of reactivity 2, and change the sign of the Enthalpy
Reaction 1 X + 12O₂ ⇒ XO ΔH = -607.3 kJ
Reaction 2 XO + CO₂ ⇒ XCO₃ ΔH = - 356.9 kJ
3.- Sum up the reactions
X + 12O₂ + XO + CO₂ ⇒ XO + XCO₃
X + 12O₂ + CO₂ ⇒ XCO₃ ΔH = -964.2 kJ
