MAXImum [283]

Answer:

Physical changes example is sugar dissolves in coffee
Chemical changes examples are iron rusts, gasoline burns in an engine and a candle burns.

Explanation.

Physical changes depend on only physical state, not on composition, which can be separated by physical means while chemical changes depend on composition and only separated by chemical ways.
As in case of iron rusting, gasoline and candle burn are cases chemical changes bcz they convert into another substance whose composition is different from other as compare to sugar which has same composition in coffee ,only state is changed from solid to liquid.

The balanced equation for the reaction between iron sulfied and water is best represented by?

nika2105 [10]

FeS + H₂O → FeO + H₂S

Explanation:

Iron Sulfide = FeS

Water = H₂O

FeS + H₂O → FeO + H₂S

To balance this equation, we can use a mathematical method. This involves solving simple algebraic equations

aFeS + bH₂O → cFeO + dH₂S

a,b,c and d are the coefficients needed to balance up the equation:

Conserving Fe: a = c

S: a = d

H: 2b = 2d

O: b = c

let a = 1, c= 1, b = 1 d = 1

The balanced equation is: FeS + H₂O → FeO + H₂S
