All of them are soluble salt.
First one dissociates into two ions.
The second one dissociates into 3 ions.
The third dissociate into 4 ions. therefore, Al(NO3)3
Answer
Hello
I think the reaction is like this FeO+OFe²O³
And the balance reaction is 2Fe+OFe²O³
Explanation:
At first we should find sth that has more atoms than the other then for example we realized that we have two atoms of Fe in Fe²O³ then put 2 before FeO and now we have 2 atoms of Fe in right side and 2 atoms of Fe in left then Oxygen in FeO change to 2 atoms of Oxygen and we have an other one in right side that they become 3 atoms of Oxygen and now we have 3 atoms of Oxygen in both right and left side.
Finally our reaction balanced.
Good luck
When the reaction equation is:
HgBr2(s) ↔ Hg2+(aq) + 2Br-(aq)
So Ksp expression = [Hg2+] [Br-]^2
assume the solubility S = X = 2.66 x 10^-7 M
and from the reaction equation :
we can see that [Hg2+] = X
and the [Br-] = 2 X
so by substitution in Ksp formula will can get the Ksp value:
∴ Ksp = X * (2X)^2
= 2.66 x 10^-7 * (2*2.66 x 10^-7)^2
= 7.53 x 10^-20
Answer:
The answer to your question is below
Explanation:
There are 4 types of chemical reactions:
- Synthesis is when two elements or compounds form only one compound.
- Decomposition is when 1 compound is broken into 2 or more products.
- Single replacement is when one element is replaced by another element.
- Double replacement is when the cations of two compounds are interchanged.
6.- Synthesis Al + 3Cl ⇒ AlCl₃
7.- Double replacement 2NaOH + H₂SO₄ ⇒ Na₂SO₄ + 2H₂O
8.- Decomposition Ni(ClO₃)₂ ⇒ NiCl₂ + 3O₂
9.- Combustion 2C₄H₁₀ + 13O₂ ⇒ 8CO₂ + 10H₂O
10.- Single replacement Zn + 2HCl ⇒ ZnCl₂ + H₂
Answer:
2.94 grams Nickle
Explanation:
All they are asking is to convert moles to grams
To do this, find the atomic mass of nickel using the periodic table: 58.693 g
0.05 mol * 58.693 g/1 mol = 2.93465 grams
