<span>It is true that a sudden increase in both intensity and duration of physical exercise can result in injury. The body needs time to process any changes. Muscles need to build strength and flexibility gradually and the joints need time to acclimate to changes in pressure.</span>

Produces helium, a safe noble gas<br> O Fission<br> O Fusion
egoroff_w [7]

Answer:

Nuclear fission power plants have the disadvantage of generating unstable nuclei; some of these are radioactive for millions of years. Fusion on the other hand does not create any long-lived radioactive nuclear waste. A fusion reactor produces helium, which is an inert gas.

Phosphoric acid is neutralized by potassium hydroxide according to the following reaction:
iren2701 [21]

Answer:

The answer to your question is 1.33 M

Explanation:

Data

Volume of H₃PO₄ = 24 ml

[H₃PO₄] = ?

Volume of KOH = 16 ml

[KOH] = 2 M

1 M H₃PO₄ = 3.0 M H⁺

Balanced chemical reaction

             KOH  +  H₃PO₄   ⇒   K₃PO₄  +  H₂O

Process

1.- Calculate the moles of KOH

Molarity = moles / volume

-Solve for moles

moles = Molarity x volume

-Substitution

moles = 2 x 16/1000

-Simplification

moles = 32/1000

-Result

moles = 0.032

2.- Calculate the moles of H₃PO₄

              1 mol of KOH --------------- 1 mol of H₃PO₄

 0.032 moles of KOH  --------------   x

                 x = (0.032 x 1) / 1

                 x = 0.032 moles of H₃PO₄

3.- Calculate the concentration of H₃PO₄

Molarity = 0.032 / 0.024

-Result

Molarity = 1.33
