The wavelength will go down if the velocity of the wave is constant. the formula is w=v/f
Answer:
3 Cu²⁺(aq) + 2 PO₄³⁻(aq) ⇒ Cu₃(PO₄)₂(s)
Explanation:
Let's consider the molecular equation between aqueous copper(II) chloride and aqueous sodium phosphate.
3 CuCl₂(aq) + 2 Na₃PO₄(aq) ⇒ 6 NaCl(aq) + Cu₃(PO₄)₂(s)
The complete ionic equation includes all the ions and insoluble species.
3 Cu²⁺(aq) + 6 Cl⁻(aq) + 6 Na⁺(aq) + 2 PO₄³⁻(aq) ⇒ 6 Na⁺(aq) + 6 Cl⁻(aq) + Cu₃(PO₄)₂(s)
The net ionic equation includes only the ions that participate in the reaction (not spectator ions) and insoluble species.
3 Cu²⁺(aq) + 2 PO₄³⁻(aq) ⇒ Cu₃(PO₄)₂(s)
The correct matches are as follows:
1. Big Bang theory: Theory that suggests the origin of the universe started with an explosion and expansion of a very hot, dense, compact fireball.
2. Steady state theory: Theory about the origin of the universe that suggest that the universe has and will continue to be at a steady continuous state.
3. Oscillatory universe theory: Theory about the origin of the universe that suggests the universe is a never ending cycle of expansion and contraction.
4. Nebular theory: Theory about the origin of the solar system that suggest our sun and planet formed from a cloud of dust and gas.
5. Inflation theory: Theory that upholds the big bang theory but suggest there was an extremely rapid expansion or inflation milliseconds after the big bang.
6. Condensation theory: Theory about the origin of the solar system that agree with the nebular theory but stresses the importance of interstellar dust in planet formation.

Very sorry if this is wrong!
Answer:
carbonate ion < carbon dioxide < carbon monoxide
Explanation:
Bond strength depends on the bond order of a bond. The higher the bond order, the greater the bond strength since shorter bonds are stronger than longer bonds.
The carbonate ion has a bond order of 1.33, carbon dioxide has a bond order of 2 while carbon monoxide has a bond order of 3.
Since the compound with the highest C-O bond order has the strongest C-O bond, then carbon monoxide possesses the strongest C-O bond.
