2 nf3 + 225 kj -> n2 + 3f2 is it exothermic or endothermic

Due to energy being a reactant instead of a product, the process is endothermic. The system must absorb a quantity of energy before it can react, so it must be an endothermic system.

A standard galvanic cell is constructed so that the overall cell reaction is as given below where M is an unknown metal. 2 Al3+(
jasenka [17]

Answer:

magnesium metal

Explanation:

According to the redox reaction equation, six electrons were transferred hence n=6 and F= Faraday's constant 96500C. ∆G° is given hence E°cell can easily be calculated as follows:

From ∆G°= -nFE°cell

E°cell= -∆G°/nF= -(-411×10^3/96500×6)

E°cell= 0.7098V

But for Al3+(aq)/Al(s) half cell, E°= -1.66V from standard table of reduction potentials.

E°cell= E°cathode- E°anode but Al3+(aq)/Al(s) half cell is the cathode

Hence

E°anode=E°cathode - E°cell

E°anode= -1.66-0.7098= -2.37V

This is the reduction potential of Mg hence the anode material was magnesium metal

C. A 75 lb (34 kg) boy falls out of a tree from a height of 10 ft (3 m). (3 points)
KatRina [158]

(I) kinetic energy of the boy when he hits the ground =potential energy

I. e ½mv²=mgh where g is 10ms-²

m=34kg, g=10ms² , h=3m

=34×10×3

=1020j

(i i) v²=u²+2gh

v²=0²+2×10×3

= 60

v=sqrt of 60
