Answer:
Yes.
General Formulas and Concepts:
<u>Chemistry - Stoichiometry</u>
- Balancing reactions
- Reaction prediction
Explanation:
<u>Step 1: RxN</u>
Zn + HCl → ZnCl₂ + H₂
<u>Step 2: Balance RxN</u>
Zn + 2HCl → ZnCl₂ + H₂
- Need 2 H's on both sides
- Need equal amount of Cl's on both sides
e. ice changed to gas
f.the specific heat of vaporisation is greater than heat of fusion because eventually all the ice changed to gas it becomes vaporisation
Answer:
Reaction rate
Explanation:
We are told that Ben observes how quickly some dry wood is burning in a campfire.
This is an example of reaction rate because it tells us the speed i.e. how fast the dry wood is reacting with the camp fire.
The correct answer would be D. Ca^2+ has 18 electrons. This is because 2+ means that 2 electrons have been removed, and Ca starts out with 20 electrons. As 20 - 2 = 18 electrons, D is the correct answer.
Hope this helps!
The concentration of solids is constant and usually taken equal to unity ,therefore it does not appear in the equilibrium constant ,so adding or removing solid has no effect. So According to Le Chatelet's Principle the amount of solid reactant or product present does not have an impact on the equilibrium
What is Le Chatelet's Principle ?
The position of the equilibrium in a chemical reaction can be predicted with the aid of Le Chatelet's Principle in response to changes in temperature, concentration, or pressure. This is crucial, especially for industrial applications where it's crucial to predict and maximize yields.
According to Le Châtelet's principle, if a dynamic equilibrium is upset by changing the conditions, the equilibrium position will move to compensate for the change and restore the equilibrium.
