Iron is produced from its pretty according to the equation : 2Fe2O3 + 3CO --- 4Fe + 3CO2 Calculate the percentage yield, if 500 tonnes of the one produced 145 tonnes of iron.. 3. Glycine, an amino acid, has one nitrogen atom per molecule. If the percentage by mass of Nitrogen in glycine is 18.7%. Calculate the relative molecular mass of the amino acid 4. Why is Hydrogen fluoride a liquid at room temperature, unlike hydrogen chloride 5. Orbitals with the same energy are called what? 6. When Cao is heated to a very high temperature, it emits a light termed? 7. All the following properties are true of solids Except A. cannot be compressed B. Does not evaporate C. Has a definite weight D. Has a definite shape E. Has a definite volume 8. Calculate the volume of CO2 released when 30dm^3 of air was ed over an excess of red hot coke. (All gas volumes measured at the same temperature and pressure. Air is about 20% oxygen by volume) 9. What is the colour of bromothyl blue in acidic solution 10.

Medical student I can see you are brainstorming seriously. My cousin wants to study biochemistry and he had 267 in jamb pls is he good to go with that score.

abeylysis92:pm me thru Nairaland. |
Eben331: 6:55pm On Sep 01, 2018 |
abeylysis92:No. You can make changes since your biodata is still there. |
abeylysis92(m): 9:46pm On Sep 01, 2018 |
Bigboy289: [C] It prolongs the life of the filament, since it is inert and it's not easily oxidized.. I think |
Bigboy289(m): 10:57pm On Sep 01, 2018 |
abeylysis92:i also have the same thought |

Eben331: I got 60cm(c)... for the image to be at 2F, that mean the object is also from d extreme 2F1. therefore U equals V 1/v+1/u equals 1/F I/120+1/120 equals 1/F 2/120 equals 1/F therefore, F equals 120/2 which is 60cm I think the magnification is just there to cause confusion or so I'm open to correction, bosses in the house |
