Iron oxide, known as hematite, is the main source of iron for the steel industry. It is created when iron and oxygen combine. It can be described using the following equation:

4Fe + 30, -- 2Fe,0,

What type of reaction took place?

A Double replacement
B. Decomposition
C. Single replacement
D. Synthesis

battery with hi vtge high val resist in series

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

a=d/t

a="triangle"v/t

explanation:

a = acceleration

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
