UkoKoshka [18]

Answer:

Follows are the answer to this question:

Explanation:

pleas find the attachment file.

Formula for ΔE:

\Delta E =  \sum \text{Bond energy of recatants}- \sum \text{Bond energy of Products}

    = 6 ( B.E_{C-C}) +12 (B.E_{C-H}) +(B.E_{o \ = \ o}) - 6(B.E_{C-C})-10(B.E_{C-H}) -( B.E_{C=0}) -2(B.E_{0-H})\\\\ =  \bold{2 (B.E_{C-H}) +(B.E_{o \ = \ o})  -( B.E_{C=0}) -2(B.E_{0-H})}\\\\

to calculate the value for ΔE put the value in above formula:

Balance the following chemical reaction: _NaOH + _H2SO4 -----&gt;_Na2SO4 +_H20
Dima020 [189]

Answer:

Sodium Hydroxide + Sulfuric Acid = Sodium Sulfate + Water

2NaOH + H2SO4 → Na2SO4 + 2H2O

Explanation:

To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.

Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.

Ionic charges are not yet supported and will be ignored.

Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.

Compound states [like (s) (aq) or (g)] are not required.

You can use parenthesis () or brackets [].

When one material is rubbed against another, electrons jump readily from one to the other. why don’t protons do that?
Pachacha [2.7K]
Protons are held inside nucleous with neutrons with large amount of force. So mere rubbing doesn't help in breaking the nucleous of an atom. But electrons are far from the nucleous and the force of attraction is smaller. So electrons can jump readily while protons can't
