Explanation:
The net ionic equation of a reaction is obtained from the complete ionic equation after removing the spectator ions.
The balanced chemical equation for the reaction of sodium bicarbonate with acetic acid is shown below:
The complete ionic equation is:
The net ionic equation is:
Answer:The net ionic equation is shown below:
Answer:
When two atomic orbitals come together to form two molecular orbitals, one molecular orbital will be lower in energy than the two separate atomic orbitals and one molecular orbital will be higher in energy than the separate atomic orbitals.
Explanation:
<em>Which of the following statements is TRUE? </em>
- <em>Electrons placed in antibonding orbitals stabilize the ion/molecule.</em> FALSE. Electrons in the antibonding orbitals destabilize the ion/molecule.
- <em>The total number of molecular orbitals formed doesn't always equal the number of atomic orbitals in the set.</em> FALSE. The total number of molecular orbitals is always equal to the number of atomic orbitals in the set.
- <em>When two atomic orbitals come together to form two molecular orbitals, one molecular orbital will be lower in energy than the two separate atomic orbitals and one molecular orbital will be higher in energy than the separate atomic orbitals.</em> TRUE. The orbital with lower energy will be the bonding orbital and the one with higher energy will be the antibonding orbital.
- <em>A bond order of 0 represents a stable chemical bond.</em> FALSE. A chemical bond is stable if the bond order is higher than zero.
2C₂H₂ + 5O₂ ---> 4CO₂ + 2H₂O
2 mol.....5 mol
2 mol C₂H₂ --- 5 mol O₂
35 mol C₂H₂ --- X mol O₂
X = (35×5)/2
X = 87,5 mol O₂
Explanation:
<h2>1.-Ate-contains 3 elements in which one is oxygen</h2><h2>2.-ite-contains 3 elements in which one is Oxygen but the oxygen is less than that of -Ate</h2><h2>3.-ide has 2 elements</h2>
