Answer:

salt water freezes just like fresh water, but at lower temperatures. Fresh water freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit , because of the salt in it. When salt water freezes, however, the ice contains very little salt because only the water part freezes.

Answer this question and you’ll get 20 points Explain how energy is transfers using the major forms of energy in a circuit descr

svetlana [45]

Answer:

When the fuel is burnt, the hot gas rushes out of the rocket due to the great heat and pressure produced by the release of chemical energy in burning. Energy transfer is the movement of energy from one location to another. Energy transformation is when energy changes from one type to another.

Which element or compound has lost electrons in this oxidation-reduction reaction? 4li 2coo â†’ 2co 2li2o a. coo b. li2o c. li d

Nady [450]

Answer:

Correct option is C.

Explanation:

Such type of chemical reaction that involves a transfer of electrons between two species is known as oxidation-reduction or redox reaction.

Redox reaction is oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.

For this reaction:

On reactant side:

Oxidation state of oxygen, cobalt, lithium = -2 ,+2, 0

While on product side of reaction:

Oxidation state of cobalt, oxygen, lithium = 0, -2, +1

Here, oxidation reaction take place because oxidation state of lithium is increased. While the oxidation state of cobalt in reducing, it is gaining electrons and so it undergoes reduction reaction.

So, Option C (Li) is correct.
