If the power source in a motor was to be replaced with an electrical load, and the armature was turned by hand, then what device
timofeeve [1]

Answer:

This question doesnt make much sense but ill try to answer it.

A brushed DC electric motor is an internally commutated electric motor designed to be run from a direct current power source. Brushed motors were the first commercially important application of electricity. If the shaft of a DC motor is turned by an external force, the motor will act as a generator. DC Motor rotation does have to do with the voltage polarity and the direction of the current flow.

Can someone solve Thierry two problems
olga2289 [7]

Answer:

5.00 × 10⁻⁴ mol HCl; 100 mL NaOH

Step-by-step explanation:

3. Moles of HCl

<em>Data: </em>

V(HCl) = 500 mL

    pH = 3

<em>Calculations: </em>

            pH = 3

      [H₃O⁺] = 10⁻³ mol·L⁻¹

              V = 500 mL × (1 L/1000 mL) = 0.500 L

Moles HCl = volume × concentration

                 = 0.500 L × (10⁻³ mol/1 L)

                 = 5.00 × 10⁻⁴ mol

4. Volume of NaOH

NaOH + HCl ⟶ NaCl + H₂O

<em>Data: </em>

[NaOH] = 0.01 mol·L⁻¹

   [HCl] = 0.02 mol·L⁻¹

V(HCl) = 50 mL

<em>Calculations: </em>

    Moles HCl = 0.050 L × (0.02 mol/1 L)

                      = 1.0 × 10⁻³ mol

Moles NaOH = 1.0 × 10⁻³ mol HCl × (1 mol NaOH/1 mol HCl)

                      = 1.0 × 10⁻³ mol NaOH

      V(NaOH) = 1.0 × 10⁻³ mol NaOH × (1 L NaOH/0.01 mol NaOH)

                      = 0.1 L NaOH     Convert to millilitres

                      = 100 mL NaOH
