So your question ask to complete the table in your problem using the law of constant composition and the table summarize the amount of iron and chlorine produced upon the decomposition of the sample iron and the data that would complete the table is FeCi3(162.2), Fe(0.508), Cl(0,967)

Answer : The mass of Fe and Cl in sample B is 3.341 g and 6.371 g respectively.

Explanation :

Law of definite proportion : It is defined as a given compound always contains exactly the same proportion of elements by weight.

The balanced chemical reaction will be,

2FeCl_3\rightarrow 2Fe+3Cl_2

First we have to calculate the ratio of mass of FeCl_3.

\text{Ratio}=\frac{\text{Mass of }FeCl_3 \text{in sample A}}{\text{Mass of }FeCl_3 \text{in sample B}}

\text{Ratio}=\frac{3.785g}{1.475g}=2.566

Now we have to calculate the mass of Fe and Cl in sample B.

\text{Mass of Cl in sample B}=2.566\times \text{Mass of Cl in sample A}

\text{Mass of Cl in sample B}=2.566\times 2.483g=6.371g

and,

\text{Mass of Fe  in sample B}=2.566\times \text{Mass of Fe in sample A}

\text{Mass of Fe in sample B}=2.566\times 1.302g=3.341g

Therefore, the mass of Fe and Cl in sample B is 3.341 g and 6.371 g respectively.

pickupchik [31]

Answer: I italicize for checking

  1. <em>Rocks are preserved through the process.</em>
  2. <em>Rocks change from one type to another.</em>
  3. <em>Different rock groups are interrelated.</em>
  4. Rocks change from one type to another in a specific order.
  5. <em>Environmental conditions influence a change in rock type.</em>

Explanation:

Rocks are preserved, as in you can't destroy them completely, but no, they don't <em>stay </em>the same they change.

Discussion Questions 1. Given the equilibrium equation for a general reaction, A + B  C + D, explain what happens to the reacta
ANTONII [103]

Answer:The equilibrium constant for a given reaction is [concentration of products]/[concentration of reactants].

Explanation:

Equilibrium constant=[concentration of products]/[concentration of reactants]

The concentration of reactant  molecules is maximum at time 0 and it  decreases as the reaction proceeds, The concentration of product molecules increases.At equilibrium the concentration of reactants and products are equal.

All the changes would occur in accordance with the LeChateliers principle.

For the given reaction the following changes would occur:

a When CO is removed from the reaction mixture so the reaction would shift towards right that is in forward direction as we are decreasing the concentration of CO so the system would try to increase the concentration of CO and that can happen by more production of CO.

b Since the above reaction is an endothermic reaction so when we would be adding heat to the system that is when we would increase the temperature  the reaction would shift forwards as  more heat energy is absorbed by reactants  to form more products.

c When more CO₂ is added so more amount of reactants are added to the system so the system would try to decrease the amount of reactants that is CO₂ and hence more amount of products would be formed.The reaction would shift in forward direction.

d Since  this reaction is endothermic in nature so when we remove the heat from reaction hence even less amount of heat is present in the system and so the reaction shift in backward direction as the reaction cannot proceed without enough amount of heat.
