Voltage<span>, </span>also called<span> electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field.
So ACTUALLY an "electromotive force", but of your answer choices.

It is called condensation
Answer:
The average rate is 2.84 X 10⁻³ Ms⁻¹
Explanation:
Average rate = -0.5*Δ[HBr]/Δt
given;
[HBr]₁ = 0.590 M
[HBr]₂ = 0.465 M
Δ[HBr] = [HBr]₂ - [HBr]₁ = 0.465 M - 0.590 M = -0.125 M
Δt Change in time = 22.0 s
Average rate = -0.5*Δ[HBr]/Δt
Average rate = - 0.5(-0.125)/22
Average rate = 0.00284 Ms⁻¹ = 2.84 X 10⁻³ Ms⁻¹
Therefore, the average rate is 2.84 X 10⁻³ Ms⁻¹
B. Compound
Calcium nitrate is an inorganic compound
<h3>
Answer:</h3>
Ammeter
<h3>
Explanation:</h3>
- Lets ask ourselves the following questions
What is an Ammeter?
- An ammeter is a device that is used to measure electric current in a circuit.
How is it used ?
- To measure the electric current the ammeter is placed in series with the components of the circuit and the reading on the ammeter is taken.
What is electric current?
- Electric current is a measure of the flow of electrons in a given circuit per unit time. It is therefore, the measure of the rate of flow of electrons in a circuit.
