The equation NaHco3+hc2h3o2=nac2h3o2+h2co3 is already balanced.
Reaction information:
Nahcolite + Acetic Acid = Sodium Acetate + Carbonic Acid
Reactants:
Nahcolite - NaHCO3 :
Molar Mass, Oxidation State
Acetic Acid - HC2H3O2
Molar Mass, Oxidation State, Ethanoic Acid, Methanecarboxylic Acid, Ch3-Cooh, Acetic Acid; Glacial, etc
(NaHCO3 + HC2H3O2 = NaC2H3O2 + H2CO3)
as you move in the periodic table from left to right he atomic radius decreases...
this is how they are avenged in periodic table, now you can answer which is having smaller radius and also which has larger radius
Al Si P S
Here's how to do it:
<span>Balanced equation first: </span>
<span>Mg + HCl = H2 + MgCl2 unbalanced </span>
<span>Mg + 2 HCl = H2 = MgCl balanced </span>
<span>Therefore 1 mole Mg reacts with 2 moles Hcl. </span>
<span>50g Mg = ? moles (a bit over 2; you work it out) </span>
<span>75 g HCl = ? moles (also a bit over 2; you work it out) </span>
<span>BUT, you need twice the moles HCl; therefore it is the Mg that is in excess. (you can now work out how many moles are in excess, and therefore how much mg is left over). </span>
<span>So, 2 moles HCl produce 1 mole H2(g) </span>
<span>therefore, the amount of H2 produced is half the number of moles of HCl </span>
<span>At STP, there are X litres per mole of gas (look it up - about 22 from memory) </span>
<span>Therefore, knowing the moles of H2, you can calculate the volume</span>
the bond will break
The bond will dissolve (break) if the electron absorbs a photon and is moved from a bonding molecular orbital to an antibonding orbital since there is no longer an overall stabilizing interaction.
<h3>What is an antibonding orbital?</h3>
An antibonding molecular orbital is the molecular orbital created by the destructive overlapping of atomic orbitals.
<h3>Why is it called antibonding orbital?</h3>
- Every atom will add one electron to the bond that makes up the lower energy bond.
- To prevent interacting with the other two electrons, the additional electron will occupy a higher energy state.
- The antibonding orbital is the name of this higher energy orbital.
<h3>What orbitals form an antibond?</h3>
- The bonding orbitals are home to electrons that spend the majority of their time between the nuclei of two atoms, whereas the antibonding orbitals are home to electrons that spend the majority of their time outside the nuclei of two atoms.
<h3>When an electron was elevated to the antibonding orbital, what happened?</h3>
- In contrast, putting electrons in antibonding orbitals will make the molecule less stable.
- The energy levels of the orbitals will determine how many electrons are filled.
- The lower energy orbitals will be filled first, and then the higher energy orbitals.
