Antarctica is covered in ice. which of the following would you expect to be true of antarctica? a. the ice reflects no radiation. b. the ice has no heat capacity. c. the ice has a high albedo. d. the ice is immune to isolation.

The ice has a high albedo.

Explanation:

C

Explanation:

Albedo is a measure of ‘whiteness’  or reflectivity which is also the rate at which a surface is able to reflect a percentage of solar radiation it receives. White surfaces have a higher albedo which is why Arctic and Antarctic regions with lots of ice sheets have a high albedo. They play a big role in regulating global temperatures. The larger the ice sheet cover in the antarctic and arctic regions, the more they reflect solar radiation back to space hence keeping the temperatures on earth from rising considerably.

Explanation:

The unbalanced nuclear equation is

It is convenient to replace the question mark by an atomic symbol, , where x = the atomic number, y = the mass number, and Z = the symbol of the element .

Then your equation becomes

The main point to remember in balancing nuclear equations is that **the sums of the superscripts and the subscripts must be the same on each side of the equation**.  

Then

74 = x + 0, so x = 74

33 = y + 1, so y = 33 -1 = 32

Element 33 is germanium, so the nuclear equation becomes
