Answer:
More precisely, in centipede, the excretory system consists of a pair of Malpighian tubules that run from the midgut to the hindgut. Waste exits the body through the anus at the posterior end. Excretory organs of Prawn are known as green glands or antennal glands

Answer:
0.5
Explanation:
Magnesium has valency +2 and iodine has valency -1
they react to form MgI2
This shows that to form one Mole of MgI2 we need one Mole of Mg and 2 moles of I.
But here we have only one Mole of Iodine which completely reacts with half mole of Mg. To find the amount (i.e mass) of MgI2 we multiply 0.5 × (240+2(1270)) we get 1390g.
I hope you understood
