it is a combination reaction or oxidation reaction.
Answer : The chemical reaction which takes place when Magnesium wire is burnt in air is Combination Reaction. Another type of reaction also takes place which is called Exothermic Reaction because heat or energy gets released when it is burnt in air.
The energy that was released by the candy is calculates using the below formula
Q=Mc delta T
Q= heat energy
m= mass (500g)
C= specific heat capacity) = 4.18 j/g/c
delta t =change in temperature = 25- 21 = 4 c
Q= 500 g x 4.18 j/g/c x 4c = 8360 j
0.83 m/s seems the correct answer, hope it helps
The smallest particle is the white blood cells because they are the ones that help you breathe
Boiling water results in no chemical change. If water is just heated to its boiling temperature then there is a physical change.
