Answer:
Explanation:
The Solar System is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, the dwarf planets and small Solar System bodies

Answer:
[CO2] > [N2] > [He]
Explanation:
The relative concentration of CO2, N2 and He depends on the solubility of each gas in water. The more soluble in water a gas is, the greater its concentration in aqueous solution.
Among the gases listed, CO2 is most soluble in water hence it is expected to have the greatest concentration in solution followed by N2. Helium gas is insoluble in water hence it has the least concentration in the aqueous solution.
Answer:
1. Limiting reactant.
2. Product.
3. Theoretical yield.
4. Reactants.
5. Actual yield
Explanation:
1. The limiting reactant. The limiting reactant is the reagent that is completely up in the reaction.
2. Product. Product is the result obtained From a reaction and the amount of product formed is determined by the limiting reactant
3. Theoretical yield. This is the result obtained from the stoichiometry calculations.
4. Reactant. Reactant are the starting material for a chemical reaction. The amount of the reactants determines the theoretical yield (products)
5. Actual yield. This is the result obtained from the experiment carried out in the laboratory.
