Answer:
Any situation that has a path that stops at the same position that it started from has a displacement of zero.
Explanation:
The chemical reaction that appears between the given compounds, ferrous sulfate and barium hydroxide, is a double replacement reaction. This is due to the activity series of the metals being able to replace either of them in the compound. To balance the chemical reaction, ensure that the number of moles of each of the atoms in both sides of the equation are equal.
The answer to this item is,
FeSO₄(aq) + Ba(OH)₂(aq) --> BaSO₄(s) + Fe(OH)₂ (aq)
As can be seen in the resulting equation, it does not need to be modified to balance it.
Answer:
66 g of CO₂
Solution:
The Balance Chemical Reaction is as follow,
C₂H₂ + 5/2 O₂ → 2 CO₂ + H₂O
Or,
2 C₂H₂ + 5 O₂ → 4 CO₂ + 2 H₂O ------- (1)
Step 1: Find out the limiting reagent as;
According to Equation 1,
56.1 g (2 mole) C₂H₂ reacts with = 160 g (5 moles) of O₂
So,
125 g of C₂H₂ will react with = X g of O₂
Solving for X,
X = (125 g × 160 g) ÷ 56.1 g
X = 356.5 g of O₂
It means for total combustion of Ethylene we require 356.5 g of O₂, but we are only provided with 60.0 g of O₂. Therefore, O₂ is the limiting reagent and will control the yield.
Step 2: Calculate Amount of CO₂ produced as;
According to Equation 1,
160 g (5 mole) O₂ produces = 176 g (4 moles) of CO₂
So,
60.0 g of O₂ will produce = X g of CO₂
Solving for X,
X = (60.0 g × 176 g) ÷ 160 g
X = 66 g of CO₂
20 g is the answer to make it a saturated solution
