<u>Answer:</u>

X = 350 kJ/mol

<u>Explanation:</u>

According to the question:

<em>Energy needed when breaking bonds  +  1640 kJ/mol   =   Energy released when forming bonds</em>

<em>∴ </em>2 (C - C) + 8 (C - H) + 5 (O = O) + 1640 = 6(C = O) + 8(O - H)

⇒ 2 (X) + 8 (410) + 5 (500) + 1640 = 6 (740) + 8 (460)

⇒ 2X  +  7420  =  8120

⇒ 2X = 700

⇒ X = 350 kJ/mol

26 Given the balanced equation representing a reaction:4Al(s) + 3O2(g) ==&gt; Al2O3(s)
dsp73
(2) gains 12 moles of electrons, easy, because it must retain the same mass in a balanced equation, so if there is no exterior mention of any electrons, such as the notation +12e-, than we must assume that the Oxygen took it at any rate.

How can water and gravity work together to erode soil,sediment,and rock
Sunny_sXe [5.5K]
Ever seen a waterfall ? what do you think happens when all that water slams into the ground below ? same as when you turn a hosepipe on a flowerbed.

also, there's hydraulic cracking where water gets into cracks and freezes, splitting rocks apart.

fast moving water can carry sediment and roll rocks along the bottom. if the water slows down, it drops the rocks and heavier sediment. if it floods a field, say, then drains away, the grass will also filter smaller particles out, or the water might evaporate and leave fine sediment behind.
