There are 3 moles of H_{2} O  are produced in neutralization when 1. 5 mole of Mg(OH)_{2}  reacts with H_{2} SO_{4

The neutralization reaction between magnesium hydroxide and sulfuric acid is given as,

Mg(OH)_{2}  +  H_{2} SO_{4 → MgSO_{4} + 2H_{2} O

from above chemical equation , we can conclude the molar ratio = 1:2

It means two moles of water molecule is produce from one mole of magnesium hydroxide.

So, number of moles of water molecules produced from  1. 5 mole of magnesium hydroxide = 1. 5 mole× 2 = 3 moles

Therefore,  number of moles of water molecules produced from  1. 5 mole of magnesium hydroxide is 3 moles.

Write the balanced equation for the reaction of 1 mol of naoh with 1 mol of h2po4
solmaris [256]

Answer:

3 NaOH +  H₃PO₄ ----->  Na₃PO₄ + 3 H₂O

Explanation:

This appears to be a double-displacement reaction. In these reactions, the cation of one compound is swapped with the cation of another. Therefore, Na⁺ (from NaOH) is swapped with H⁺ (from H₃PO₄). When constructing the new compounds, you may need to alter the amount of each ion within a particular compound to to make it neutral.

New Product #1: Na₃PO₄

----------> Na⁺ and PO₄³⁻

----------> +1 + 1 + 1 + (-3) = 0

New Product #2: H₂O (or HOH)

----------> H⁺ and OH⁻

----------> +1 + (-1) = 0

Now that you know the products, you need to balance the chemical equation. An equation is balanced when there is an equal amount of each element on both sides. These amounts can be modified by adding coefficients.

The unbalanced equation:

NaOH + H₃PO₄ -----> Na₃PO₄ + H₂O

<u>Reactants</u>: 1 sodium, 5 oxygen, 4 hydrogen, 1 phosphorus

<u>Products</u>: 3 sodium, 5 oxygen, 2 hydrogen, 1 phosphorus

The balanced equation:

3 NaOH +  H₃PO₄ ----->  Na₃PO₄ + 3 H₂O

<u>Reactants</u>: 3 sodium, 7 oxygen, 6 hydrogen, 1 phosphorus

<u>Products</u>: 3 sodium, 7 oxygen, 6 hydrogen, 1 phosphorus

**I was having trouble balancing the equation with the reactant H₂PO₄⁻. From my experience, I believe this compound may have been mistyped. As such, I used H₃PO₄. Please let me know if the reactant was written properly**

Why only electrons stick to oil drop in millikan's experiment however protons are also present there?
marishachu [46]

Explanation:

probably because, X rays are used to ionise the gas molecules, which is loss of electrons, these electrons are absorbed by oil drops

explain why particles of colloidal solution donot settle down when left undisturbed , while in the case of suspensions they do .
Leni [432]

Answer:

the partial of colloidal are smaller and they are not heavy whereas the partial of suspension are larger but they are heavy and less movement thus they settle down due to gravity

The coordination sphere of a complex consists of ________. The coordination sphere of a complex consists of ________. the ligand
sammy [17]

Answer:

The coordination sphere of a complex consists of <u><em>the central metal ion and the ligands bonded to it.</em></u>

Explanation:

The Coordination Compounds are sets of a central metal ion attached to a group of molecules or ions that surround it. They are also called metal complexes or simply complexes. Then they are compounds that have a central atom surrounded by a group of molecules or ions, the latter called ligands.

The central atom must have empty orbitals capable of accepting pairs of electrons, with the transition metals being the ones with the greatest tendency. Because of this, they can act as Lewis acids (electron pair acceptors). The ligands have unshared electron pairs, then acting as Lewis bases (electron pair donors).

When forming a complex, it is said that the ligands coordinate to the metal and the central metal and the ligands attached to it constitute the coordination sphere of the complex.

Finally, <u><em>the coordination sphere of a complex consists of the central metal ion and the ligands bonded to it.</em></u>
