The answer is c to the question
I can’t see the piston lol
The correct answer is silt. Silt have the lowest threshold velocity. Silt is a granular substance that is like a sand and clay. Silt may occur as a mixed sediment with water and that water moves the molecules in a minimum speed rate.
Answer:
Net ionic equation:
H⁺(aq) + OH⁻(aq) → H₂O(l)
Explanation:
Balanced Chemical equation:
HClO₂(aq) + NaOH(aq) → H₂O(l) + NaClO₂ (aq)
Ionic equation:
H⁺(aq) + ClO₂⁻(aq) + Na⁺(aq) + OH⁻(aq) → H₂O(l) + Na⁺(aq) + ClO₂⁻ (aq)
Net ionic equation:
H⁺(aq) + OH⁻(aq) → H₂O(l)
The ClO₂⁻(aq) and Na⁺ (aq) are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.
Spectator ions:
These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
The mass of the liquid is 280 g.
Mass = 200 mL × (1.4 g/1 mL) = 280 g
