B) Salad
heterogeneous mixtures have a non-uniform composition with components in at least two different phases
Answer:
sodium + chlorine --> sodium chloride
From Boyle's law the volume of a fixed mass of a gas is inversely proportional to the pressure at a constant absolute temperature. Thus; K = PV Hence; P1V1 =P2V2 0.5 × 24 = 4× P2 P2 = 12/4 = 3 atm Therefore; the pressure will go from 24 atm to 3 atm
Answer:
C. It shows you that the formation of water is a reversible reaction, which contains hydrogen and hydroxide ions.
Explanation:
The equation is
H₂O(ℓ) ⇌ H⁺(aq) + OH⁻(aq)
It also shows that water can behave as either an acid or a base, because it can produce both H⁺ and OH⁻ ions.
A and B are both wrong. Although the statements are correct, they don't say anything about acids and bases.
