Precipitate is silver sulfate and the net ionic equation is
2Ag⁺(aq) + SO₄²⁻(aq) → Ag₂SO₄(s)
<u>Explanation:</u>
The given reaction is the reaction of sodium sulfate with silver nitrate and as the reaction goes we will get the precipitate of Silver sulfate and the balanced reaction is given as,
Na₂SO₄ + 2 AgNO₃→ Ag₂SO₄↓ + 2 NaNO₃
Here silver sulfate is obtained as a precipitate.
Net ionic equation is the equation in which the ions involved in the reaction only taken into account that is ions forming precipitate, whereas the other ions are considered as spectator ions, ions do not involved in the reaction.
Here the net ionic equation is:
2Ag⁺(aq) + SO₄²⁻(aq) → Ag₂SO₄(s)
All the elements in one group have the same number of valence electrons.
An isotope is different from an element by the number of neutrons it has.
Answer:199mL
Explanation:
Let V ml be the volume of blood in animal.
When 1.0 ml sample is added, total volume becomes V+1.0ml. Its activity is 1000 dpm.
After equilibrium, 2.0 ml of the sample had activity of 10 dpm.
Hence, after equilibrium, the activity of V+1.0 ml of blood sample will be 10/2 (V+1.0ml)=1000dpm
Hence, V=199ml.
