miss aya heyy: plz answer these qz fe me: important:!! :) and thxx 1.what is the IUPAC NAME OF:H2FC-CF3 2. CAN WE WRITE THIS LIKE THAT: CHHH-CHH-OH?? YE3NE STRCHTURAL FRMULA..CONDENSED ONE 3.DO WE NUBER ALDHYDE..LIKE 2-BUTANOL??? 4.IS PAPER COMPST OR GOOD FR PLANTS? 5.PLOYMERIZATION IS PHYSICAL? AND KEEF MNA3MELA ?? BEE HEAT?? 6.HOW DO WE BALANCE NO2+H2-->NH3 +H20 7.DO WE DEFINE THE LEWIS DOT SYMBOL WHEN WE MAKE IT FOR IONS? I MEAN THE NORMAL DEFITION 8.WE SAY 3 COV. BNDS BW 3H AND N 9. WE A COVALENT BON IS FRMED BW 1C AND H OR 2 COVALENTS BONDS?? LOVEE U MISS AYA AND SOORY IZA RA7 A5REK 3ALA IL PORFOLIO (VERA)..LOL LOVEEEEE UU <3 <3
the iupac name for the compound your prepared it:1,1,1,2 tetra fluoroethane no you can't write CHHH....it's not a correct way Of course polymerization is not a physical change...Since it's a chemical reaction...then it's a chemical change, where we obtain a new substance which is the polymer Yes, we say 3 covalent bonds between N and 3 hydrogens,since a triple covalent bond is 3 covalent bonds but only between 2 atoms... The last question is not clear. Love you too dear, study well
Hello to all, this blog was prepared to answer your questions while studying chemistry for the official examination.
Every now and then, I'll post a problem along with the solution. Try to solve the problem first, then have a look at the solution.
