I'm pretty sure your answer should be CaCl2. Hope this helps! =^-^= (if I need to explain more just let me know.)
Answer:
C.
Fe goes from 0 to 2+, oxidation. It is reducing agent
N goes from 5+ to 2+, reduction. It is oxidizing agent
Explanation:
Oxidation number
Fe (s) has 0
FeSO4 has 2+
HNO3 N has 5+
NO N has 2+
The water cycle is the endless process that connects all of that water. It joins the Earth's oceans, land, and atmosphere. The Earth's water cycle began about 3.8 billion years ago when rain fell on a cooling Earth, forming the oceans. ... Precipitation that falls onto land flows into rivers, streams, and lakes.
The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid (ice) and vapor.

Oxygen is gas. It has 2 O atoms. Atomic mass of 1 O atom is 16 amu. So molecular mass of O2 = 2 x 16 = 32 amu.
Now, mass of 6.023 x 10 ^23 = 32 amu.
Therefore mass of 3.01 x 10^23 = 32 x 3.01 x 10^23 / 6.023 x 10 ^23 = 15.99
= ~16 gm
Answer:
Explanation:
Continental tropical air masses are extremely hot and dry. Arctic, Antarctic, and polar air masses are cold. The qualities of arctic air are developed over ice and snow-covered ground. Arctic air is deeply cold, colder than polar air masses.
