True talk

Odilop: correct!!

ATP(energy) + Luciferin (substrate)+ Luciferase(enzyme) + O2(oxidizer) = light (photons)

The product of the reaction btw hydroxylamine and an aldehyde or ketone is called ___

DrPaulB: Transition elemnts form coloured ions due to the definitve property which is an incompletely filled or an unpaired 3d electrons

yes boss

drstan: Hmmm been a while dont really no well about it do, but in one of my mcb course it said something about luciferine in the presence of an enzyme called luciferase, so is d two substance luciferine and luciferase

correct!!

I SEE U #JARYEH.

zhukafa:

thanks all, I appreciate. I also have some more questions for you friends to help me out with. I will post them later. once more, thanks.

welcome bro.more question...

Am in

Yap Dr bode was correct I did a mistake.

Dr_Bode:
Which one exactly? Frm eqn 1 or eqn 2?

the mole is correct.

oluafolabi:

Lmaooo!! Be nice.

how?

What are the two subtance which when react with oxygen and atp produces light in fire flies??

zhukafa: A sample of 0.500g of impure CaC03 was dissolved in 50.0cm³ of 0.100moldm–³ HCL and the remaining acid was titrated against 5.0cm³ of 0.12mol dm–³ NaOH solution. find the percentage of CaCO3 in the sample.

Mole of acid used is. 50/1000*0.1
=0.005moles
No of mole of caco3
2HCL+CaCO3=CO2+CaCL2+H2O
2 mole of HCL=1 moles of CaCO3
0.005mole give 0.005/2 mole of CaCO3
0.0025 moles of cacO3
Mass of caCO3=0.0025*100
=0.25g
Thus, percentage =0.25/0.5
=0.5 *100%
=50%

valdprof: pls wat do we call chem reactions dat release energy to the environment ..pls

exothermic or exergonic reaction
