Explanation:
Speed is the rate of an object moving along a path, whereas velocity is the direction of motion
Electricity is the flow of electric charge
The answer should be 2 down in the larva
Answer:
Explanation:
Since all sodium salts and all nitrates are soluble, the insoluble product must be lead(II) bromide.
The equation for the equilibrium is
PbBr₂ ⇌ Pb²⁺ + Br⁻
I/mol·L⁻¹: 0.0140 0.0024
= [Pb²⁺][Br⁻]²
[Pb²⁺] = 0.0140 mol·L⁻¹
[Br⁻] = 0.0024 mol·L⁻¹
Answer:
Option D. T
Explanation:
Enthalpy change (ΔH) is simply the difference between the heat content of the product (Hp) and the heat content of the reactant (Hr). Mathematically, it is expressed as:
Enthalpy change (ΔH) = Heat of product (Hp) – heat of reactant (Hr)
ΔH = Hp – Hr
From the diagram given above, the difference between the heat content of product and the heat content of reactant is T.
Therefore, the enthalpy change of the reaction is T.
