You must first get a common denominator by multiplying (1/3) by 5 and (-2/5) by 3 to get the equation (5/15)+(-10/15)= -5/15 which can be simplified to 1/3.
Answer:
we would die, because we need oxygen, and the gravity would just be gone, and then blood would just go to are head and then the air will leave are bodys and we will explode
Explanation:
This is an oxidation-reduction (redox) reaction:
2 Mg0 - 4 e- → 2 MgII
(oxidation)
2 O0 + 4 e- → 2 O-II
(reduction)
1) Calculate the number of moles of Cu SO4 . 5H20 by dividing the specified mass by the molar mass.
2) The ratio of production given by the equation is 1 mol of Cu SO4 . 5 H2O to 1 mol of Cu SO4=> 1:1, meaning that the number of moles of Cu SO4 produced is the same number of moles of Cu SO4.5H20 heated.
3) Finally mutiply the number of moles of Cu SO4 by its molar mass and there you have the mass of Cu SO4 produced.
