Answer:

okay but give me brainliest

Explanation:

A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth's surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope. Volcanic flows are called lahars.

Iron metal reacts with elemental oxygen to form rust according to the unbalanced reaction, Fe(s) + O2(g) → Fe2O3(s),. What is th

pochemuha

Answer:

c. 3

Explanation:

The unbalanced reaction expression is given as:

Fe + O₂ → Fe₂O₃

To balance the expression gives the coefficient of oxygen.

Assign the coefficients a,b, c and use a mathematical approach to solve this problem:

aFe + bO₂ → cFe₂O₃

Conserving Fe: a = 2c

O: 2b = 3c

Now let c = 1, a = 2, b = $\frac{3}{2}$

Multiply through by 2,

a = 4, b = 3 and c = 2

4Fe + 3O₂ → 2Fe₂O₃

The coefficient of O₂ is 3
