Answer is: D. is oxidized.

Reducing agent is an element  or compound that loses an electron to another chemical species in a redox chemical reaction and they have been oxidized.

For example, chemical equation: Ca + H₃PO₄ → Ca₃(PO₄)₂ + H₂.

Oxidation reaction: Ca⁰ → Ca⁺² + 2e⁻ /×3.

3Ca⁰ → 3Ca⁺² + 6e⁻

Reduction reaction: 6e⁻ + 2H₃⁺¹ → 3H₂⁰.

Balanced chemical equation: 3Ca + 2H₃PO₄ → Ca₃(PO₄)₂ + 3H₂.

Calcium is stronger reducing agent than hydrogen, gives electrons easier.

Calcium is oxidized, it changes oxidation number from 0 to +2.

What do organisms have based on their functions?
mote1985 [20]
Unicellular organisms, cells perform all the basic actions and functions required for living like nutrition, respiration, reproduction etc.

In multicellular organisms, cells divide their tasks on the basis of "DIVISION OF LABOUR" to specialize in certain functions besides respiration etc. Like conduction in neurons, excitation in muscles, RBC production by bone marrow etc.

Suppose 0.035 moles of HCl is dissolved in enough water to produce 750 mL of solution. What is the pH
zhuklara [117]

Answer:

pH = 1.33

Explanation:

Because HCl is a strong acid, each mole of HCl will completely dissociate into H⁺ and Cl⁻ species.

Now we calculate the molar concentration (molarity) of H⁺:

  • Molarity = moles / volume

(750 mL ⇒ 750 / 1000 = 0.750 L)

  • Molarity = 0.035 moles / 0.750 L
  • Molarity = 0.0467 M

Then we calculate the pH of the solution:

  • pH = -log [H⁺]
  • pH = -log (0.0467 M)
  • pH = 1.33

What is the speed of a man walking for 30 meters and he walked for 5 seconds ​
aliya0001 [1]

Answer:

<h2>6 m/s</h2>

Explanation:

The speed of the man can be found by using the formula

v =  \frac{d}{t}  \\

d is the distance

t is the time taken

From the question we have

v =  \frac{30}{5}  \\

We have the final answer as

<h3>6 m/s</h3>

Hope this helps you
