Answer:
the answer is= NUCLEAR FISSION, NUCLEAR FUSSION, RADIOACTIVE DECAY.
We have to determine if the given compound is soluble or insoluble in water.
The given compound is copper (II) hydroxide, 
. According to the solubility rules the hydroxides of all metal ions are insoluble except that of ammonium and the alkali metal ions. So copper(II) hydroxide will be insoluble in water. In aqueous solution, copper (II) hydroxide would exist as a sparingly soluble compound in which the undissociated compound remains in equilibrium with the ions 
and 
. The equilibrium would remain mostly towards undissociated form.
Therefore, is insoluble in water.
Answer:
63 mL
Explanation:
Data given:
density of CCl₄ = 1.59 g/mL
mass of CCl₄ = 100.0 g
Volume = ?
Solution:
To calculate density formula will be used
d = m/v
rearrange the above equation
v = m/d . . . . . . (1)
where
d = density
m = mass
v = volume
put values in above formula 1
v = 100.0 g / 1.59 g/mL
v = 63 mL
so. the volume of CCl₄ = 63 mL
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)
