Answer:
32° fahrenheit
Explanation:
I hope this helped! I took a test and got it correct.
Density = Mass / Volume
Density = 2.74g / 3.10cm³
Density = 0.88 g/cm³
In my opinion, the correct answer among the choices above is option B. AN atom having four electrons in its valence shell is capable of single, double, or triple covalent bonds. This is because 4 electrons of the atom can be shared with other atoms.
Answer:
No, it isn't a spontaneous reaction.
Explanation:
A spontaneous reaction is a reaction that requires no outside intervention to start.
All chemical reactions require energy.

net ionic equation:
SO₄²⁻ (aq) + Ba²⁺ (aq) → BaSO₄ (s)
Explanation:
We have the following chemical reaction:
H₂SO₄ (aq) + Ba(OH)₂ (aq) → BaSO₄ (s) + 2 H₂O (l)
Now we write the ionic equation:
2 H⁺ (aq) + SO₄²⁻ (aq) + Ba²⁺ (aq) + 2 OH⁻ (aq) → BaSO₄ (s) + 2 H⁺ + 2 OH⁻ (aq)
We remove the spectator ions to obtain the net ionic equation:
SO₄²⁻ (aq) + Ba²⁺ (aq) → BaSO₄ (s)
where we have:
(aq) - aqueous
(s) - solid
(l) - liquid
