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)
I believe it is convection
Answer:
58425.84 kJ is released when 4.337 pounds of liquid ethanol are burned.
Explanation:
Given that:-
When 1 gram of liquid ethanol is burnt, 29.7 kJ of energy is released.
The conversion of pounds to gram is shown below as:-
1 pound = 453.6 gram
Given mass of liquid ethanol = 4.337 pounds.
So,
4.337 pounds = 453.6*4.337 grams = 1967.2 grams
Thus,
When 1967.2 gram of liquid ethanol is burnt, 29.7*1967.2 kJ of energy is released.
<u>58425.84 kJ is released when 4.337 pounds of liquid ethanol are burned.</u>
Answer:
No, the metal is not pure gold because density is equal to mass divided by volume and in this case we end up with about 15.3, making this metal less dense than gold.
