السلام عليكم ورحمة الله وبركاته
البنات الي ماخذين تمهيدي كيميا هالكورس
فيه كوزات على الويب سايت مال الدكاتره الي منزلين تمهيدي كيمياء
فياريت الي تعرف الاجوبه مالت كوز جابتر2 لا تبخل علينا
وجزاكم الله الف خير
بالتوفيق يارب
و إنشالله أقدر أساعدج !!
يالغلا انا عندي مذكرررة اخذتها من قائمة المستقله فيها كل الاجوبه حقت الكويزات ملوووت الجابترات كلها
اذا تبينها انا بالخدمة
