Answer:
D. 4, 3, 2.
Explanation:
Oxygen exists as the molecule O2. So it is:
4Fe + 302 ---> 2Fe2O3
Answer:
Answer below
Explanation:
A - false
B - true
C - false
In chemistry there is a principle that polar compounds are soluble with other polar compounds and non-polar compounds are mutually different.
Thus, sodium chloride is an ionic salt (polar) so it is not soluble in the benzene (non-polar) covalent compound, but it is soluble in water that is polar.
The ionic compounds will be soluble in polar solvents and not soluble in non-polar solvents, regardless of whether they are organic or inorganic.

Hello mr/mrs (name) I unfortunately couldn't pay attention to the class due to some issues I had therefore I don't know what we are doing in class
OR
Hello mr/mrs (name) I could understand what we were doing in class I would like it if you could break it down more or explain better to me
OR just say something it had something to do with your internet such as
Hello mr/mrs (name) I didn't understand what you were saying during our class due to some of my internet issues I was have throughout the day. I hope you can explain what we did during the class.
Those may be some of my excuses I've used before
they have worked for me:)
I don't know if that helped?:/
Answer:
SO₄²⁻(aq) + Ba²⁺(aq) ⇒ BaSO₄(s)
Explanation:
Let's consider the molecular equation that occurs when aqueous solutions of ammonium sulfate and barium nitrate are mixed.
(NH₄)₂SO₄(aq) + Ba(NO₃)₂(aq) ⇒ BaSO₄(s) + 2 NH₄NO₃(aq)
The complete ionic equation includes all the ions and insoluble species.
2 NH₄⁺(aq) + SO₄²⁻(aq) + Ba²⁺(aq) + 2 NO₃⁻(aq) ⇒ BaSO₄(s) + 2 NH₄⁺(aq) + 2 NO₃⁻(aq)
The net ionic equation includes only the ions that participate in the reaction and the insoluble species.
SO₄²⁻(aq) + Ba²⁺(aq) ⇒ BaSO₄(s)
Answer: idk I have that question too , sorry to get ur hopes up high thinking this was an answer. PERIOTTTT
