The answer to this question would be C. Because some natural elements can't be mixed with certain solubles and won't work as effectively as other solutes. And the temperature affects the rate the solute works in. So, C is your answer.
When two waves come in contact with each other while traveling on the same medium, its called constructive interference. Constructive interference happens when two waves come together.
MZn: 65 g/mol
mZnCl₂: 65g+35,5g×2 = 136 g/mol
.....................
Zn + 2HCl -----> ZnCl₂ + H₂
65g.......................136g............
65g Zn ---- 136g ZnCl₂
3,57g Zn ---- X
X = (3,57×136)/65
X = 7,47g ZnCl₂
The answer is C. They lower the activation energy of an elementary step of a reaction
This makes the reaction rate to increase since less energy is required to make a reaction occur.
Answer:
See explanation
Explanation:
We have to remember that for any <u>equilibrium expression constant</u> we can use the general reaction:
With a equilibrium expression:
We have to <u>divide products by reagents and use the coefficient (in the balanced reaction) as exponents</u>. So:
The reaction is <u>already balanced</u>. So, we can write the equilibrium expression:
In this case, all the compounds have <u>gaseous state (g)</u>. So, we can change the concentration ([]) by the <u>pressure of each compound</u>:
