Answer: The reaction does occur.
Explanation: For the reaction of aqueous strontium sulfide and aqueous copper(II) sulfate, the reaction follows:
This reaction is a type of precipitation reaction.
The precipitate formed is CuS which is black in color.
Answer:
75 ml of 0.1M base neutralizes 25 ml of 0.1M acid, which means the acid has 0.3 moles/L of H ion
but that means each molecule of the acid has 3 times as many H ions aH ions in a molecule of NaOH
which means the formula for the acid must be H3A and
the value of x in
HxA is 3
Explanation:
75ml of a solutipn of 0.1moL l-1 NaOH neutralises 25ml of a solution of an acid. The formula of the acid is HxA and the concentration of the acid is 0.1mol l-1. What is the value of x?
the concentration of both the and the base are the same at 0.1M
the base...NaOH has 0.1 moles/L of OH ion
75 ml of 0.1M base neutralizes 25 ml of 0.1M acid, which means the acid has 0.3 moles/L of H ion
but that means each molecule of the acid has 3 times as many H ions aH ions in a molecule of NaOH
which means the formula for the acid must be H3A and the value of x in
HxA is 3
The answer to this question is particles yes girl work slay that chem
Answer:
Water has the greatest ΔEN
ΔEN H₂O → 3.4 - 2.1 = 1.3 Option D.
Explanation:
We should find the Electronegativity data in the Periodic table for all the elements:
C : 2.6
O: 3.4
H: 2.1
S: 2.6
N: 3.0
a. ΔEN CO₂ → 3.4 - 2.6 = 0.4
b. ΔEN H₂S → 2.6 - 2.1 = 0.5
c. ΔEN NH₃ → 3 - 2.1= 0.9
d. ΔEN H₂O → 3.4 - 2.1 = 1.3
