Potassium and iodine have formed a bond. Prior to this the potassium gave up an electron. It became a _____. positive ion neutra

Clarification:

The pertinent information is outlined as follows.

m = 10.0 kg = 10,000 g (since 1 kg = 1000 g)

Starting temperature of block 1, = (100 + 273) K = 373 K

Starting temperature of block 2, = (0 + 273) K = 273 K

Therefore, the heat lost by block 1 equals the heat received by block 2

It's important to convert the temperature into Kelvin as (50 + 273) K = 323 K.

Additionally, the relationship between enthalpy and temperature change is as follows.

=

= 1243550 J

or, = 1243.5 kJ

Next, determine the entropy change for block 1 as follows.

=

=

= -554.12 J/K

Now, the entropy change for block 2 is as follows.

           =

           =

           = 647.49 J/K

Thus, the total entropy is the sum of the entropy changes of both blocks.

                   = -554.12 J/K + 647.49 J/K

           = 93.37 J/K

In conclusion, for this reaction, the outcome is 1243.5 kJ and is 93.37 J/K.

Answer:- 0.134 seconds

Solution:- The speed is given as and the circumference is 24900 miles which is same as the distance light have to covered. It asks to calculate the time required to cover this distance by the light.

Unit conversion is needed from miles to meters since the speed is given in meters per second.

1 mile = 1609.34 meters

Thus,

= 40072566 meters

Now,

Rearranged for time, that gives:

Inserting the values:

= 0.134 seconds

Hence, light would take 0.134 seconds to traverse the indicated distance. The answer without the unit is 0.134.
