Answer: (a) The products are
and AgCl. The balanced equation is
.
(b) The type of reaction is double displacement reaction.
Explanation:
(a) The complete reaction equation will be as follows.
![BeCl_{2}(aq) + 2AgNO_{3}(aq) \rightarrow Be(NO_{3})_{2}(aq) + 2AgCl(s)](https://tex.z-dn.net/?f=BeCl_%7B2%7D%28aq%29%20%2B%202AgNO_%7B3%7D%28aq%29%20%5Crightarrow%20Be%28NO_%7B3%7D%29_%7B2%7D%28aq%29%20%2B%202AgCl%28s%29)
Number of atoms on reactant side are as follows.
- Be = 1
- Cl = 2
- Ag = 2
= 2
Number of atoms present on product side are as follows.
- Be = 1
- Cl = 2
- Ag = 2
= 2
Here, number of atoms on both reactant and product side are the same. Hence, it is a balanced chemical equation.
(b) A reaction in which two reactant species tend to change their ions with each other and form new compounds. This type of reaction is called double displacement reaction.
As the given reaction is as follows.
![BeCl_{2}(aq) + 2AgNO_{3}(aq) \rightarrow Be(NO_{3})_{2}(aq) + 2AgCl(s)](https://tex.z-dn.net/?f=BeCl_%7B2%7D%28aq%29%20%2B%202AgNO_%7B3%7D%28aq%29%20%5Crightarrow%20Be%28NO_%7B3%7D%29_%7B2%7D%28aq%29%20%2B%202AgCl%28s%29)
This shows that ions are being exchanges by the reactants
and
. The ions are
,
,
and
.
Therefore, this reaction is a double displacement reaction.

WOW, I gave you the answer, i used a periodic table, i got the mass of gold and i linked a helpful link my teacher gave me because we used it in a lab once.
Answer:
- NH₃ is the limiting reactant.
- Theoretical yield = 120 kg
Explanation:
- 2NH₃ (aq) + CO₂ (aq) → CH₄N₂O (aq) + H₂O (l)
First we <u>convert the given masses of reactants to moles</u>, using their <em>respective molar masses</em>:
- 68.2 kg NH₃ ÷ 17 kg/kmol = 4.01 kmol NH₃
- 105 kg CO₂ ÷ 44 kg/kmol = 2.39 kmol CO₂
2.39 kmol of CO₂ would react completely with (2.39 * 2) 4.78 kmol of NH₃. There are not as many NH₃ kmoles so <u>NH₃ is the limiting reactant.</u>
We <u>calculate how much urea would form with a 100% yield</u>, using the <em>moles of limiting reactant</em>:
- 4.01 kmol NH₃ *
= 2.00 kmol CH₄N₂O
We <u>convert that amount to kg</u>:
- 2.00 kmol CH₄N₂O * 60 kg/kmol = 120 kg CH₄N₂O
Finally we <u>calculate the percent yield</u>:
- 87.5 kg / 120 kg * 100% = 72.9 %
