Answer:Water is attracted to the sodium chloride crystal because water is polar and has both a positive and a negative end. The positively charged sodium ions in the crystal attract the oxygen end of the water molecules because they are partially negative.
Answer:
The boiling point of the fluoromethane (CH3F) is higher than that of fluorine (F2).
Answer:
pH = 6.964 which rounds to 7.0 if 2 sig figs
Explanation:
Ka₁ * Ka₂ = x
2.4x10⁻⁴ * 4.9x10⁻¹¹ = 1.176x10⁻¹⁴
√1.176x10⁻¹⁴ = 1.084435337x10⁻⁷
pH= -log[H⁺]
pH= -log[1.084435337x10⁻⁷]
pH= 6.964796339
the correct answer is thermal or light
