What is the mole ratio of water to H3PO4?
Artyom0805 [142]

Answer:

Explanation:

Phosphoric acid H₃PO₄ is produced from reaction of water and tetraphosphorus decoxide  P₄O₁₀ as follows

P₄O₁₀ + 6 H₂O = 4 H₃PO₄

In this reaction 6 molecules of H₂O and one molecule of  phosphorus compound P₄O₁₀ is needed to produce phosphoric acid , ie the conversion factor of water to acid is 6 / 1

This ratio is called mole ratio of water to H₃PO₄.

So the required ratio is 6 : 1 .

  • Objects “fall” toward the center of Earth.
  • Objects accelerate at a rate of 9.8 m/s each second.
  • Objects are pulled by Earth more strongly than they pull on Earth.

Explanation:

The gravity of the earth is the force which attracts the object to the center of the earth. When the any object with mass falls under the action of the gravity attains the acceleration of 9.8 m/s^2.

  • Objects “fall” toward the center of Earth.
  • Objects accelerate at a rate of 9.8 m/s each second.
  • Objects are pulled by Earth more strongly than they pull on Earth.
