Answer:
The answer to your question is KNO₃ + PbI₂
Explanation:
Data
Chemical reaction
KI + Pb(NO₃)₂ ⇒
Process
We know that this is a double displacement reaction because there are two reactants and each reactant has a cation and an anion (a positive atom and a negative atom or a polyatomic molecule).
To know the products just interchange the cations in each molecule considering the oxidation numbers.
K⁺¹I⁻¹ + Pb⁺²(NO₃)₂⁻¹ ⇒ K⁺¹NO₃⁻¹ + Pb⁺² I₂⁻¹
or
KI + Pb(NO₃)₂ ⇒ KNO₃ + PbI₂
Answer:
Explanation:
Hello!
In this case, since the decomposition of potassium chlorate is:
We can see a 2:3 mole ratio between potassium chlorate and oxygen (molar mass 32.0 g/mol), thus, via stoichiometry, we compute the mass of oxygen that are produced by the decomposition of 2.50 moles of this reactant:
Best regards!
Answer:
Yes, yield.
Explanation:
N2(g) + 3 H2(g) → 2 NH3 (g) balanced equation
First, find limiting reactant:
Moles H2 = 1.83 g x 1 mole/2 g = 0.915 moles H2
Moles N2 = 9.84 g N2 x 1 mole/28 g = 0.351 moles N2
The mole ratio of H2: N2 is 3:1, so H2 is limiting (0.915 is less than 3 x 0.351)
Theoretical yield of NH3 = 0.915 mol H2 x 2 mol NH3/3 mol H2 = 0.61 moles NH3
Answer:
Students have investigated what's going on in the fictional town of Westfield, they learned that the mysterious reddish-brown substance in the water is actually rust, which formed because of a chemical reaction between the iron pipes and the fertilizer substance in the water.
