Answer is: H₂O → H⁺ + OH⁻.
Water dissociates (autoionization) to form hydrogen ions (H⁺) and hydroxide (OH⁻) ions. The protons (H⁺) hydrate as hydroxonium ions( H₃O⁺).
The Kw (the ionic product for water) at 25°C is 1·10⁻¹⁴ mol²/dm⁶ or 1·10⁻¹⁴ M². Concentration of hydrogen ions and hydroxide ions in pure water are the same.
Answer:
basically electrons produced by the cathode are attracted towards anode positive terminal it is also called beta rays because they consist of negative charge particles in the chamber
Explanation:
Answer:
Volume is 0.00233mL
Explanation:
Hello,
The density of a substance is the mass per unit volume of that substance.
Density = mass / volume
To solve this question, we need to get our data first.
Data;
Density = 19.3g/mL
Mass = 45mg = 0.045g
Volume = ?
Density = mass / volume
Density (ρ) = mass (m) / volume (v)
ρ = m / v
v = m / ρ
v = 0.045 / 19.3
v = 0.00233mL
The volume of the substance is 0.00233mL
Answer:
The acceleration is positive because they’re speeding up 4. An airplane touches down on the runway at 37m/s. After 8 seconds, the airplane has slowed to a velocity of 5 m/s.
