What mass (in g) of lithium metal can be produced by the electrolysis of molten LiCl for 23.93 hr with an electrical current of 17.7?

1.828 g

Explanation:

The half-reaction is:

First we calculate the coulombs:

Then we calculate the number of lithium moles, using Faraday's constant:

Finally we convert moles to grams:

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
