Answer:
585 kcal
.
Explanation:
- From the balanced equation:
<em>2Cl₂(g) + 7O₂(g) + 130 kcal → 2Cl₂O₇.</em>
130 kcal are needed to produce 2 mol of Cl₂O₇.
<em><u>Using cross multiplication:</u></em>
130 kcal are needed to produce → 2 mol of Cl₂O₇.
??? kcal are needed to produce → 9 mol of Cl₂O₇.
<em>∴ The energy required to produce 9.00 mol of Cl₂O₇ </em>= (130 kcal)(9 mol)/(2 mol) = <em>585 kcal.</em>
Explanation:
Modeling crustal deformation is a very important process that helps to study plate interaction that clearly can be used to predict the likelihood of an earthquake.
Earthquake is a sudden displacement or movement with the earth that transmits elastic energy.
- Earthquakes can have shallow or deep focus depending on their location and the terrain.
- Movement on the earth are mostly noticeable along plate margins.
- This results in a world-wide movement of the broken slabs of the earth moving on the weak asthenosphere.
- It is impossible to go deep within the lithosphere to identify unstable earth.
- The uneven distribution of stress is very important in this process.
- As plate moves, the lithosphere deforms creating stresses in some area and relieving other places of stress.
- Continuous collection of stress data using strain mapping gives important parameters that can be modeled.
- Areas with high amount of stress and more movement have the highest tendency of producing earthquakes.
- A computer model is used to carry out this prediction.
- Some other factors contributes to the rapid movement but stress are by far the most important of all.
- By this, we can easily and readily hypothesize the causes of an earthquake and possible measures to mitigate it.

Balanced chemical equation for the reaction between sulfuric acid & solid aluminum hydroxide to form liquid water and a soluble salt is 3H₂SO₄ + 2Al(OH)₃ Al₂(SO₄)₃ + 6H₂O.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those in which all entities are present in same amount on both sides of the chemical equation.
Balanced chemical reaction for the given compounds will be shown as:
3H₂SO₄ + 2Al(OH)₃ Al₂(SO₄)₃ + 6H₂O
Above chemical equation is the balanced equation as all atoms are present in same amount on the left side as well as on the right side of the reaction.
Hence balanced equation is 3H₂SO₄ + 2Al(OH)₃ Al₂(SO₄)₃ + 6H₂O.

They speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind.
Answer:
The answer to your question is 2NaCl + 2H₂O ⇒ 2NaOH + Cl₂ + H₂
Explanation:
Original chemical equation
NaCl + H₂O ⇒ NaOH + Cl₂ + H₂
Reactant Element Products
1 Na 1
1 Cl 2
2 H 3
1 O 1
This reactions is unbalanced
2NaCl + 2H₂O ⇒ 2NaOH + Cl₂ + H₂
Reactant Element Products
2 Na 1
2 Cl 2
4 H 4
2 O 2
Now, the reaction is balanced
