السلام عليكم ورحمة الله وبركاته
وطبعا يا شباب مش هننسى الكيمياء التحليلية
اللى هيكون مكانها هنا باذن الله

اولا لسلام عليكم ورحمة الله وبركاته
ثانيا نبدأ الاسئلة فى جزء الدكتورة منال

[د\بوسى ربيع]

أكيد بيصلوا وزمانهم جايين
خلينا نشتغل احنا وهما يجو براحتهم

[dr/noony]

COMPLETE

4-THE easier the ****l to loss electrons the more it act as .......and need ......potential
5-there must be potential differance =..........to cause 2 half reaction

[dr/noony]

1-How can you get standered electrode potential
2-If you have an un known electrode potential What will you do to know it
3-How can you calculate the following
A-oxidation number
B-electrode potential
4-How can you balance a redox equation

[dr/noony]

انتوا فين يا شباب
هو ده كان اتفاقنا ؟؟؟؟؟؟؟؟؟؟؟

[dr/noony]

على كل حال أنا هكمل الاسئلة وانتوا ابقوا حلوها براحتكم
