Answer:
at P = 101 KPa ⇒ S = 2.1 g/L
Explanation:
Henry's law:
∴ K: Henry's constant
∴ <em>C</em> is the concentration ≡ Solubiluty (S)
∴ S = (8.4 g/L)*(Kg/1000 g)*(1000 L/m³) = 8.4 Kg/m³
∴ P = (404 KPa)*(1000 Pa/KPa) = 404000 Pa
∴ Pa = Kg/ms²
⇒ S = K(404000 Pa) = 8.4 Kg/m³
⇒ K = 2.079 E-5 s²/m².......the henry's constant for this gas
at P = 101 KPa = 101000 Pa
⇒ S = (2.079 E-5 s²/m²)*(101000 Kg/ms²)
⇒ S = 2.1 Kg/m³ = 2.1 g/L
Answer:
All carbohydrates, including sugar, therefore contain the same three elements: carbon, hydrogen and oxygen. Different arrangements of these elements form single units to make different types of carbohydrates. Glucose, for instance, is a single-unit carb with six carbon atoms, 12 hydrogen atoms and six oxygen atoms.

Answer:
2
Explanation:
The sample has halved twice.
1/2 of 1/2 is 1/4, and 1/2 of 1 is 1/2.
Answer:
Properties of transition elements
they are all metals and that most of them are hard, strong, and lustrous, have high melting and boiling points, and are good conductors of heat and electricity.
Heat applied to reactant causes a faster chemical reaction. Heat is considered as ACTIVATION ENERGY.
Activation energy is the minimum amount of energy which reactants must possess in order to undergo a chemical reaction. When heat is applied to a particular set of reactants, the heat increases the kinetic energy of the reacting particles, thus enabling them to move around more rapidly. This increases the rate of collision among the reacting particles and empower the reacting particles to overcome the energy barriers and to form the products.
