Classify each material as an alloy or ceramic
alloy- Bronze,brass, steel and glass
Ceramic- brick and tile
<u><em> Explanation</em></u>
<u><em>Alloy</em></u> is a metal made up by combining two or more metallic elements.
for example, bronze is made up by alloying tin with copper.
<u><em>Ceramic </em></u>materials is an inorganic,non metallic which is often crystalline oxide,nitride or carbide material.
For example, Tiles are made up of natural clay sand and water.
Answer:
carbohydrates are energy giving foods that warm the body and could be in different forms
Hey there!
The correct answer is sodium or sodium chloride. Basically, table salt.
Hope this helped!
The
chemical reaction is represented as:<span>
2A(g) = B(g) + C(g)
To determine the equilibrium concentration of A, we make use of the equilibrium
constant, Kc, given above. It is expressed as the ratio of the equilibrium
concentrations of the products and the reactants. For this reaction, it is
expressed as:
Kc = [B] [C] / [A]^2
From the problem statement, we are given the following
Kc = 0.035
Volume = 20.0 L
Initial concentrations: [B] = 8.00 mol / 20.0 L = 0.4 M
[C] = 12.00 mol / 20.0 L = 0.6
M
Since the initial reactants are B and C, the reaction is reversed as well as
the Kc.
Kc = [A]^2 / [B][C]
We use the ICE table:
B
C A
I 0.4 0.6
0
C -x -x
+x
------------------------------------------
E 0.4 - x 0.6 - x
x
Kc = x^2 / (0.4-x) (0.6-x) = 0.035
solve for x,
x = 0.07691 = [A]</span>
