Answer:
1
Explanation:
Trigonal planar geometry is shown by the compounds where hybridization of central atom is .
In hybridization, three hybrid orbitals are equally spaced at an angle of 120°.
Some of the compounds having hybridization are , , etc
In hybridizationm, one s-orbital and 2 p-orbitals are involved.
Total no. of orbitals present in p-subshell is 3.
As 2 is involved in hybridization, therefore no. of unhybridized orbital in hybridization is 1.
Answer:
2Mg(s) +O₂(g) → 2MgO(s)
Explanation:
Mg(s) +O₂(g) → MgO(s)
When a chemical equation is balanced, the number of atoms of each element is equal on both sides of the arrow. We usually balance O and H last.
In this case, the number of Mg atoms is equal on both sides. Thus, let's move on to balance the O atoms. On the left side, there are 2 O atoms, while there is only 1 O atom on the left side. Thus, write a '2' in front of MgO.
Mg(s) +O₂(g) → 2MgO(s)
Now, the number of Mg atoms is not equal. Write a '2' in front of Mg to balance it.
2Mg(s) +O₂(g) → 2MgO(s)
The equation is now balanced with 2 Mg atoms and 2 O atoms on each side.
The acid in a battery is an electrolyte.
Answer:
Reaction equilibrium will shift to the left (higher molar volume side of process).
Explanation:
For gas phase reactions, changes in pressure-volume conditions cause a stress on the process equilibrium shifting away from the applied pressure-volume change.
LeChatlier's Principle states for a gas phase reaction at equilibrium ...
if the pressure is increased (volume decreased) the reaction will shift toward the lower molar volume side of the process.
if the pressure is decreased (volume increased) the reaction will shift toward the higher molar volume side of the process.
if the sum of molar volumes of reactants equals the sum of molar volumes of products, changes in pressure-volume conditions will NOT affect the equilibrium stability. Example => H₂(g) + Cl₂(g) ⇄ 2HCl(g) will not be affected by P-V changes as ∑Vm(reactants) = ∑Vm(products).
Plate tectonics is the theory that Earth's crust is composed of many plates that are moving slowly over time.
