How do waves interact with matter ?
velikii [3]
Waves interact with matter in several ways. The interactions occur when waves pass from one medium to another. Besides bouncing back like an echo, waves may bend or spread out when they strike a new medium. These three ways that waves may interact with matter are called reflection, refraction, and diffraction.

-FeS2+-O2-&gt;-Fe2O3+-SO2 What coefficient should be placed in front of SO2 to balance the equation?
NISA [10]

Answer:

8 should be placed in front of SO₂.

Explanation:

The easiest way to solve this question is by writing the <u>entire</u> balanced equation:

4FeS₂ + 11O₂ -> 2Fe₂O₃ + 8SO₂

We can achieve this by first balancing the Fe, then S, and finally the O.

We can also double check our answer by counting the number of each element on both sides:

-Reactants: 4 Fe, 8 S, 22 O

-Products: 4 Fe 8 S, 22 O

Since they match, our equation is balanced, and the coefficient in front of SO₂ is 8.

Elis [28]

First we need to calculate the number of moles of FeS_{2}:

number of moles = mass (grams) / molecular mass (g/mol)

number of moles of FeS_{2} = 198.2/120 = 1.65 moles

From the chemical reaction we deduce that:

if            4 moles of FeS_{2} produces 8 moles of SO_{2}

then  1.65 moles of FeS_{2} produces X moles of SO_{2}

X = (1.65×8)/4 = 3.3 moles of SO_{2}

Now we can calculate the mass of SO_{2}:

mass (grams) = number of moles × molecular mass (grams/mole)

mass of SO_{2} = 3.3×64 = 211.2 g
