Answer:
2Na⁺ (aq) and 2OH⁻(aq)
Explanation:
Spectator ions:
Spectator ions are those ions which are same on both side of chemical reaction. These ions are same in the reactant side and product side. Their presence can not effect the chemical equilibrium that's why when we write the net ionic equation these ions are neglect or omitted.
Given ionic equation:
Ba⁺²(aq) + 2OH⁻(aq) + 2Na⁺ (aq) + CO²⁻₃(aq) → BaCO₃(s) + + 2Na⁺ (aq) + 2OH⁻(aq)
In given ionic equation by omitting the spectator ions i.e, 2Na⁺ (aq) and 2OH⁻(aq) net ionic equation can be written as,
Net ionic equation:
Ba⁺²(aq) + CO²⁻₃(aq) → BaCO₃(s)
Answer:
test or trial
Explanation:
When somone is doing an expirement they usually conduct tests to see if their hypothesis was valid. They could so small trials like this,
Example:
Problem: Can people taste the difference between Coca Cola and Pepsi?
Trials:
1. Yes
2. Yes
3. No
4. Yes
5. Yes
6. No
7. No
8. Yes
9. Yes
10. Yes
Based on the majority, the solution to our problem is yes, most people can taste the difference between Coca Cola and Pepsi.
