36) HCl(aq)+KOH(aq)⇒H₂O(l)+KCl(aq)
37) You can use the equation M₁V₁=M₂V₂
M₁=concentration of acid
V₁=volume of acid in orginal solution
M₂=concentration of base
V₂= the volume of based used to neutralize the acid
M₁=(0.150M KOH x 0.0185L KOH)/0.025L HCl
M₁=0.111M HCl
This equation works since we no based off of the formula in question 36 that 1 mole of KOH will neutralize 1 mole of HCl and <span>M₂V₂ is equal to the moles KOH which means it needs to equal M</span>₁V₁ since that is the number of moles HCl. (if moles HCl did not equal moles KOH the solution would not be neutralized).
Answer:
C. It shows you that the formation of water is a reversible reaction, which contains hydrogen and hydroxide ions.
Explanation:
The equation is
H₂O(ℓ) ⇌ H⁺(aq) + OH⁻(aq)
It also shows that water can behave as either an acid or a base, because it can produce both H⁺ and OH⁻ ions.
A and B are both wrong. Although the statements are correct, they don't say anything about acids and bases.
Answer:
the action or process of filtering something.
Explanation:
Filtration is a physical, biological or chemical operation that separates solid matter and fluid from a mixture with a filter medium that has a complex structure through which only the fluid can pass.
Copper(II) oxide or cupric oxide is the inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu2O or cuprous oxide. As a mineral, it is known as tenorite. It is a product of copper mining and the precursor to many other copper-containing products and chemical compounds
Answer:
See answer below
Explanation:
This is pretty easy to solve. First you need to understand that an ionic compound is usually formed between a metal and a non metal. This usually happens between elements from group 1 through group 10 or 11 of the periodic table. A covalent compound is always given in non metal elements from the periodic table, and it's usually the elements from group 13 through group 17.
Some compounds there are missing some atoms, but I manage to find this question and saw the atoms missing, so, in my answer you will see the corrected compound. so don't be surprised.
According to what I state above, then the covalent compounds are:
C₆H₅N
PCl₃
C₂H₄O
NH₃
N₂
SO₄²⁻
The ionic compounds are:
CaO
CdBr₂
WO₂
Na₂O
CsF
Hope this helps
