Answer:
c Example 1 represents a liquid and Example 2 represents a solid.
Explanation:
Example 1: Young children dancing slowly around one another
The young children dancing slowly around one another can be pictured as the flow of liquid. In liquids, the molecules are held about weakly and they slide on top of each other. They are held by weak attractive forces. This is clear picture of a liquid.
Example 2: Newborn babies sitting in their given spots in a crib
This is clear example of a solid. In a solid the molecules are held about a fixed spot. The attractive forces in liquids is very great and the molecules therein do not move about randomly.
Answer:
ICE Table Figure
a. 67.37 g 
b. 35.62 g 
c. 58.61 g
Explanation:
For the <u>ICE table </u>we have to keep in mind that we have 4 moles of
and 1 mol of
and the reactives are consumed, so for
we will have -4X and for
we will have -X. Follow the same logic we will have -4X for
.
a. <u>Mass of the product</u>
Molar mass of
= 256.52 g/mol
Molar mass of
=70.9 g/mol
Molar mass of
=135.03 g/mol
We have to find the limiting reagent in the reaction:



Divide by the coefficients in the balanced reaction:


The limiting reagent would be 
Now is posible to calculate the amount of
produced:

b. <u>Mass in excess</u>


C. <u>87%Yield</u>

Answer:
Keq = 0.217
Explanation:
Let's determine the equilibrium reaction.
In gaseous state, water vapor can be decomposed to hydrogen and oxygen and this is a reversible reaction.
2H₂(g) + O₂(g) ⇄ 2H₂O (g) Keq
Let's make the expression for the equilibrium constant
Products / Reactants
We elevate the concentrations, to the stoichiometry coefficients.
Keq = [H₂O]² / [O₂] . [H₂]²
Keq = 0.250² / 0.8 . 0.6² = 0.217
Answer:
A product in science is a substance that is formed when two or more chemicals react.
Explanation:
When a chemical reaction takes place, a new substance is often created from the atoms or molecules of the original substances. There are often multiple products formed in a reaction.
