Al(s) + 2AgNO3(aq) = Al(NO3)3(aq) + 3 Ag (s)
is a single replacement reaction
A single replacement reaction is a type of chemical reaction were element react with a compound and the element take place of another element in that compound. In the reaction above Aluminium (Al) take the place of silver (Ag) from it compound.that is AgNO3. single replacement reaction is possible because aluminium is in high in reactivity series as compared to silver.
Hello there!
The correct answer is B
Remember that acceleration is the change in velocity divided by the change in time.
So, what we need to do here is take +25 divide it by 5.0, which equals to 5
So yeah, that's how we got the acceleration :)
I hope this helps!
Good luck with your Science studies!
Answer:
Explanation:
CH₄ + H₂O(g) ⇒ CO(g)+3H2(g)
Equilibrium constant
K₁ = [CO][H₂]³ / [CH₄][H₂O]
CO(g)+H₂O(g) ⇒ CO₂(g) + H₂(g)
Equilibrium constant
K₂ = [CO₂][H₂] / [CO][H₂O]
CH₄(g)+2H₂O(g) ⇒ CO₂(g)+4H₂(g)
Equilibrium constant
K = [CO₂][H₂]⁴ /[CH₄][H₂O]²
= [CO][H₂]³ / [CH₄][H₂O] X [CO₂][H₂] / [CO][H₂O]
K₁ x K₂
K = K₁ x K₂
<span>The average atomic mass of an element is the mass you see on a periodic table for that element. It is a weighted average of all the isotopes for that element based on the percentage of how much of an element is a specific isotope and the mass of each isotope. If an element has an abundance of isotopes, the isotopes with the highest and lowest masses may be more significantly different than the average atomic mass for elements with fewer isotopes.</span>
