Cations have more protons than electrons, Anions result when atoms gain an electron.

<h3>What are electrons ?</h3>

The electron, a subatomic particle, has a negative one elementary charge electric charge. The electron, a member of the first generation of the lepton particle family, is usually regarded as an elementary particle because it has no known components or substructure.

<h3>How electrons are in an atom ?</h3>

A few straightforward rules can be used to calculate the quantity of protons, neutrons, and electrons present in an atom. The atomic number and the number of protons in the atom's nucleus are equal (Z). A neutral atom has the same number of protons and electrons as protons.

Around the nucleus, electrons are positioned in several shells. Only a fixed amount of electrons can fit in each subsequent shell. Filling begins with the innermost shell.

Answer:

  2Ba₃(PO₄)₂ +6SiO₂ ⇒ P₄O₁₀ +6BaSiO₃

Explanation:

Equating coefficients, you get ...

  aBa₃(PO₄)₂ +bSiO₂ ⇒ cP₄O₁₀ +dBaSiO₃

For Ba: 3a = d

For P: 2a = 4c

For O: 8a +2b = 10c +3d

For Si: b = d

__

Expressing everything in terms of b and c, we get ...

  d = b

  a = b/3 = 2c

From the second, b = 6c, so we have ...

  a = 2c

  b = 6c

  c = c

  d = 6c

And we can write the equation with c=1 as ...

  2Ba₃(PO₄)₂ +6SiO₂ ⇒ P₄O₁₀ +6BaSiO₃

KHP is a monoprotic acid which provides one H+ ion. How would your results be affected if a diprotic acid (such as sulfuric acid
kari74 [83]

Explanation:

A.

In a diprotic acid, 2 moles of H+ ions is released. Therefore, number of moles of H+ in a diprotic acid = 2 × number of moles of H+ of monoprotic acid.

B.

Equation of the reaction

2NaOH + H2SO4 --> Na2SO4 + 2H2O

Number of moles of H2SO4 = molar concentration × volume

= 0.75 × 0.0105

= 0.007875 moles.

By stoichiometry, since 1 mole of H2SO4 reacts with 2 moles of NaOH. Therefore, number of moles of NaOH = 2 × 0.007875

= 0.01575 moles.

Molar concentration of NaOH = number of moles ÷ volume

= 0.01575 ÷ 0.0175

= 0.9 M of NaOH.
