The correct answer is false because there isn’t 4 there is 8 atoms
Net ionic equation for
<span>HClO4(aq) + NaOH(aq) --> H2O (l) + NaClO4(aq).
</span>
for the molecular equation
<span>HClO4 (aq) + NaOH(aq) --> H2O (l) + NaClO4 (aq) </span>
<span>the ionic equation is </span>
<span>H+ + ClO4- + Na+ + OH- --> H2O(l) + Na+ + ClO4- </span>
<span>now remove the spectator ions (Na+ and ClO4-) to give the net ionic equation </span>
H+ + OH- --> H2O(l)
Answer:
this
Explanation:
What is the unit rate of the better deal? (Number answers only.)
LaTeX: \frac{160\:miles}{5\:gallons}\:or\:\frac{315\:miles}{9\:gallons}160 m i l e s 5 g a l l o n s o r 315 m i l e s 9 g a l l o n s
The better deal has a unit rate of [m] miles per gallon.
Carboxylic acids: considered as weak acids due to they ionize in solution to give -COO⁻ and H⁺, they are abundant in nature, they can form intermolecular hydrogen bonds so they exist as dimers (remember that alcohols also can form hydrogen bonds).
- Acids have higher boiling and melting points than corresponding molar mass compounds due to the formation of hydrogen bond
- Aromatic carboxylic acids are solids in nature at room temperature
Answer:
B.
Explanation:
Because the delocalised electrons are free to move.
Metallic bonds are formed by the electrostatic attraction between the positively charged metal ions, which form regular layers, and the negatively charged delocalised electrons. These are the electrons which used to be in the outer shell of the metal atoms. These delocalised electrons are free to move throughout the giant metallic lattice, so as one layer of metal ions slides over another, the electrons can move too keeping the whole structure bonded together.
This is the opposite of what happens in a giant ionic lattice, where both the positive ions and the negative ions are locked in place. If the crystal is stressed and one layer moves with respect to another, the positive ions can end up lined up with each other, and the negative ions lined up with each other. This causes repulsion, so the crystal fractures.
