The air is less dense at higher altitudes. How does this affect climate? The climate tends to be warmer due to the intensity of

sun's radiant energy at higher elevations. The climate tends to be cooler than the surrounding areas at lower elevations. The climate is the same as the surrounding locations at lower elevations.​

Calculate the number of moles of magnesium, chlorine, and oxygen atoms in 4.90 moles of magnesium perchlorate, Mg(ClO4)2.]\
Leviafan [203]

Answer:

 4.90  moles of  Mg(ClO_4)_2   will produce  (9.8) moles of  Cl^{-} ,

                                                    (4.90) moles of Mg^{2+} and

                                                    (39.2) moles of  O^{2-}

Explanation:

From the question we are told that

  The number of moles of  is  n =  4.90  \ mols

The formation reaction of Mg(ClO_4)_2  is

             Mg^{2+} + 2 Cl^{-} + 8O^{2+} \to Mg(ClO_4)_2  

From the reaction we see that

   1 mole of  Mg(ClO_4)_2  is formed by 2 moles of Cl^{-} 1 mole of  Mg^{2+} and 4  O^{2-}

 This implies that

   4.90  moles of  Mg(ClO_4)_2   will produce  (2 * 4.90) moles of  Cl^{-} ,

                                                    (1 * 4.90) moles of Mg^{2+} and

                                                    (8 * 4.90) moles of  O^{2-}

So

  4.90  moles of  Mg(ClO_4)_2   will produce  (9.8) moles of  Cl^{-} ,

                                                    (4.90) moles of Mg^{2+} and

                                                    (39.2) moles of  O^{2-}

Given the following thermochemical equation 2N2O(g) → 2N2(g) + O2(g) ∆Hº = –166.7 kJ/mol find the amount of heat that will be pr
soldi70 [24.7K]

Answer:

Explanation:

2N₂O(g) → 2N₂(g) + O₂(g)

molecular weight of N₂O = 44

∆Hº = –166.7 kJ/mol

44 g of N₂O decomposes to give 166.7 kJ of heat

2.25 g of N₂O decomposes to give 166.7 x 2.25 / 44 kJ of heat

= 8.51 kJ of heat .
