The balanced equation :
<em>2Al₂O₃⇒ 4Al+3O₂</em>
<h3>Further explanation</h3>
Given
Reaction
Al₂O₃⇒ Al+O₂
Required
Balanced equation
Solution
A chemical reaction is said to be balanced if the number of elements involved in the reaction is the same (either the reactants or the products)
The reaction above is said to be unbalanced because the number of elements Al and O in the reactants and products is not the same.
The balancing step
1. Give a coefficient
Al₂O₃⇒ aAl+bO₂
2. Make an equation
Al, left = 2, right = a⇒a=2
O, left = 3, right = 2b⇒2b=3⇒b=3/2
The equation becomes :
Al₂O₃⇒ 2Al+3/2O₂ x2
<em>2Al₂O₃⇒ 4Al+3O₂</em>
Answer:
How will it affect the environment? Is its benefit worth the cost?
Explanation:
when creating environmental policies you should always look into if it is worth it or not and how it will affect the environment
Answer: sorry can't help ya
Explanation:
Sorry it's just I don't really know how to answer this question myself wish you the best of luck ;3
The ph of a solution is 3.7
Solution:
According to the equaiton of Henderson-Hasselback
pH= pKa+ log(salt/acid)
here it is given the value of
pKa= 4.7
So,
pH = pKa+ log(0.1/0.01)
= 4.7 + log(0.1)
= 4.7–1
= 3.7.
The following problem illustrates how the Henderson-Hasselbalch equation can be used to determine how much acid and conjugate base should be combined to create a buffer solution with a specific pH.

Answer:
B
Explanation:
We are talking about the periodic table in which elements where put under different rows and columns according to their atomic number (number of protons) in ascendant order.
In rows or periods we can find trends in some properties like atomic radius, electronegativity, etc...). So they are not similar in size. Option A is a false statement.
Also, they were organized in groups or columns according to their similar electronic configuration and chemical properties (like noble gases, halogens, etc...) This means option B is the correct statement.
