The <u>correct net ionic equation</u> for the chemical equation involving the reactants Ba(OH)2(aq) and H2SO4(aq) is Ba²⁺ (aq) + 2OH⁻ (aq) + 2H⁺(aq) + SO4²⁻ (aq) --> BaSO₄(s) + H₂O(l)
<h3>Further Explanation
</h3>
The chemical reaction between Ba(OH)2(aq) and H2SO4(aq) will be given by;
Ba(OH)₂(aq) + H₂SO4(aq) --> BaSO₄(aq) + 2H₂O(l)
<h3>Net ionic equations </h3>
- Net ionic equations that do not include all ions that are present in the reactants and products.
- The equations only includes the ions that are involved in the reaction.
- The ions that are not involved in a chemical reaction are called spectator ions and are cancelled out while writing ionic equations.
- Reaction between Ba(OH)2(aq) and H2SO4(aq is an example of a neutralization reaction or a double displacement reaction.
- During the reaction Barium ion bonds with sulfate ions and forms barium sulfate which is a solid, while hydrogen ion bonds with hydroxide ion to form water which is a liquid
That is:
Ba(OH)₂(aq) + H₂SO4(aq) --> BaSO₄(s) + 2H₂O(l)
- Barium ion changes from aqueous to solid state barium sulfate there it is an ion involved in the reaction.
- Additionally, all the other ions are also involved in the reaction since they have changed their initial state. The chemical reaction has no spectator ions.
Therefore; the ionic equation required will be;
Ba²⁺ (aq) + 2OH⁻ (aq) + 2H⁺(aq) + SO4²⁻ (aq) --> BaSO₄(s) + H₂O(l)

Sustainable living is a lifestyle adopted by individuals or societies which is geared towards reducing the consumption of earths natural resources. The idea is to lower the carbon footprint by switching to sustainable modes of transport, living spaces, food consumption etc.
In the given passage, the sentences that describe sustainable living are:
1) 'I plan to buy a hybrid for better gas mileage': Since a hybrid is a combination of a petrol engine and an electric motor, it reduces the consumption of fuel and is more energy efficient.
2) 'I am able to carpool with a couple of friends from work' : Carpooling reduces the vehicles on road thereby reducing vehicle exhaust.
3) 'The architects received a LEED certification': LEED certified buildings are energy efficient constructions.
A) James Cook.
B) He put his sailors on a strict diet to see if they would get scurvy.
C) Sauerkraut.
D) He told others of this diet and that none of his sailors died of scurvy.
E) Chemicals can be found almost anywhere and almost anyone can be a scientist.
The heat change is related to specific heat as
Heat change = mass of substance X specific heat X change in temperature
So if we are considering same amount of substance
and we are starting with the same temperature
the change in temperature will be inversely proportional to the specific heat
higher the specific heat lower the temperature change
Thus the change in temperature will be least for the substance with highest specific heat.
