Express your answer as a chemical equation. Identify all of the phases in your answer. Enter noreaction if there is no reaction.

Answers

1- The original equation of the reaction is :
CrI3 + NaOH → Cr(OH)3 + NaI 
but this is not a balanced equation so we have to balance it :
-first, we have 3 I atoms on the left side and 1  I atom on the right side 
so to makes the no.of atoms on both sides equal we put 3NaI instead of NaI
CrI3 + NaOH → Cr(OH)3 + 3NaI
- then no.of Na atoms on the left side is 1 and on the right side is 3 so, we put 3NaOH instead of NaOH
CrI3 + 3NaOH → Cr(OH)3 + 3NaI
now we have :
Cr atoms = 1 on both sides
I atoms = 3 on both sides
Na atoms = 3 on both sides
O&H atoms = 3 on both sides
So the final balanced equation of our reaction is:
CrI3(aq) + 3NaOH(aq)  Cr(OH)3(s) + 3NaI(aq)

2 - the chemical equation of the second reaction is :
FeSO4 + Ba(NO3)2 → BaSO4 + Fe(NO3)2
let's see if it is the balanced equation or not?
we have:
no of Fe atom on both sides = 1
no of (SO4) atom on both sides are equal
 no of Ba atom on both sides = 1
no of (NO3) group on both sides= 2 
so this is our balanced equation, so the final equation for this reaction is:
FeSO4(aq) + Ba(NO3)2(aq) BaSO4(s) + Fe(NO3)2(aq)

4Fe + 3O2 → 2Fe2O3Iron combines with oxygen to form rust. Given the chemical reaction, how many grams of 4Fe + 3O2 would produce 10 g of rust?
A) 7 g
B) 10 g
C) 30 g
D) 70 g

Answers

Answer:

b) 10 g

Explanation:

Hi, the answer in simply: during a chemical reaction (that doesn't involve nuclear processes) the total mass involved is constant.

The total mass of the reactants equals the total mass of the products, althought the number of molecules may vary.

n(2Fe2O3)=10g/319.374amu=0.03mol

n(4Fe+3O2)=0.03 mol

m(4Fe+2O2)=Mn=319.374×0.03=9.58=10

Why do scientist use models to study atoms

Answers

Models are used to study atoms because we can never really see an atom up close, and a model is like a super magnified version of the atom. Plus, its easier to study from them because we can pin point the different characteristics of the atom (Protons, Neutrons, etc.)

Scientist use models to study atoms because you cannot either see or perceive directly what do atoms look like.

Models permit to explain in a simplified way how the atoms are constituted, and, so, figure out how they behave and how they are the bulding blocks of the matter (elements and compounds).

A model can be a drawing or structure with balls and sticks, which show in an idealized way what an atom is.

Since the scientists have discovered different facts about the atoms along the last 200 years the models of the atoms have also evolved.

The plum pudding model of the atom proposed by JJ Thompson was different of the nuclear model proposed by Rutherford, and Rutherford's was different from the planetary model proposed by Bohr, and this is different from the quantum model.
