Answer:
Lead (II) iodide
Explanation:
The reaction of lead (II) nitrate, Pb(NO₃)₂ with KI is:
Pb(NO₃)₂(aq) + 2KI(aq) → KNO₃(aq) + PbI₂(s)
This is a typical double-replacement reaction where anions and cations exchange its couple.
All nitrates are solubles, thus, KNO₃ is not the precipitate.
The only possibility of precipitate is PbI₂,
Lead (II) iodide, a yellow and insoluble solid...
Calcium citrate malate contains the calcium salt of citric acid and malic acid
Answer:
D. ![2NaBr + Cl_2\rightarrow 2NaCl + Br_2](https://tex.z-dn.net/?f=2NaBr%20%2B%20Cl_2%5Crightarrow%202NaCl%20%2B%20Br_2)
Explanation:
Hello!
In this case, for the given set of chemical reactions, it is possible to infer that D. is a categorized as redox due to the following:
Since both chlorine and bromine remain as diatomic gases, their oxidation states in such a form is 0, but as anions with lithium cations they have a charge of - according to the following reaction and half-reactions:
![2NaBr + Cl_2\rightarrow 2NaCl + Br_2](https://tex.z-dn.net/?f=2NaBr%20%2B%20Cl_2%5Crightarrow%202NaCl%20%2B%20Br_2)
![Cl_2^0+2e^-\rightarrow 2Cl ^-\\\\2Br^- \rightarrow Br_2^0+2e^-](https://tex.z-dn.net/?f=Cl_2%5E0%2B2e%5E-%5Crightarrow%202Cl%20%5E-%5C%5C%5C%5C2Br%5E-%20%5Crightarrow%20%20Br_2%5E0%2B2e%5E-)
Unlike the other reactions whereas no change in the oxidation states is evidenced.
Answer:
50 mol
Explanation:
Mass of methane = 800 g
Number of moles of CO₂ produced = ?
Solution:
Chemical equation:
CH₄ + 2O₂ → CO₂ + 2H₂O
Number of moles of methane:
Number of moles = mass/molar mass
Number of moles = 800 g/ 16 g/mol
Number of moles = 50 mol
Now we will compare the moles of methane and carbon dioxide from balanced chemical equation.
CH₄ : CO₂
1 : 1
50 : 50
