Answer:
9.9 ml of 0.200M NH₄OH(aq)
Explanation:
3NH₄OH(Iaq) + FeCl₃(aq) => NH₄Cl(aq) + Fe(OH)₃(s)
?ml of 0.200M NH₄OH(aq) reacts completely with 12ml of 0.550M FeCl₃(aq)
1 x Molarity NH₄OH x Volume Am-OH Solution(L) = 2 x Molarity FeCl₃ x Volume FeCl₃ Solution
1(0.200M)(Vol Am-OH Soln) = 3(0.550M)(0.012L)
=> Vol Am-OH Soln = 3(0.550M)(0.012L)/1(0.200M) = 0.0099 Liter = 9.9 milliliters
Answer:
38 L
Explanation:
There is some info missing. I think this is the original question.
<em>Consider the chemical reaction: C(s) + H₂
O(g) ⟶ CO(g) + H₂
(g). How many liters of hydrogen gas is formed from the complete reaction of 15.2 g C? Assume that the hydrogen gas is collected at a pressure of 1.0 atm and a temperature of 360 K.</em>
<em />
Step 1: Write the balanced equation
C(s) + H₂
O(g) ⟶ CO(g) + H₂
(g)
Step 2: Calculate the moles corresponding to 15.2 g of C
The molar mass of C is 12.01 g/mol.
Step 3: Calculate the moles of H₂ produced from 1.27 moles of C
The molar ratio of H₂ to C is 1:1. The moles of H₂ produced are 1/1 × 1.27 mol = 1.27 mol.
Step 4: Calculate the volume of H₂
We will use the ideal gas equation.
Answer:
B) The molecules were closer together when the juice pop was frozen.
Correct Answer: <span>They have small differences in electronegativity (statement 3)
Reason:
The nature of chemical bond between atoms is primarily driven by the electronegativity difference between constituent atoms. If electronegativity difference between constituent atoms is significantly higher, ionic bond formation is preferred. On other hand, low difference in electronegativity values, favours formation of covalent bond.
