harshita2003gaur: Thank you so much dear❤

jassmanakfanclub10: welcome..plz mark it as brainliest:-)

krishnakant8544: boss.. the reaction is highly EXOTHERMIC as it releases a lot of heat madam...

krishnakant8544: they are not allowing my answer they say i have put something rude but i was answering the same thing.. only correct 4th part.. i don't know why its happening..

jassmanakfanclub10: but it is written in this question that we r burning a metallic ribbon so it is clear that it is a endothermic reaction we required heat for this reaction

jassmanakfanclub10: ok we can also consider this exothermic reaction bcz heat & light is also produce when we burn a magnesium ribbon.:-)

krishnakant8544: apni galti nhi man lena aachi baat hoti hai

jassmanakfanclub10: ya:-)
