Answer:
$69.35
Explanation:
125 divided by 3.785(liters in a gallon) , you get 33.025
multiply 2.1 by 33.025 and you will get $69.35
Answer: Rotation occurs at single bonds that are sigma bonds. Rotational barrier is the amount of activation energy required to covert rotamer to another by rotation that occurs around the sigma bond(C-C single bond). Due to the presence of steric hindrance that is the nonbonding interaction effects the reactivity of ions and molecules, activation energy increases. So the rotational barrier in butenyl cation is high.
Answer:
1. The oxidation number of a free element is always 0.
2. The oxidation number of a monatomic ion equals the charge of the ion.
3. The oxidation number of H is +1, but it is -1 in when combined with less electronegative elements.
4. The oxidation number of O in compounds is usually -2, but it is -1 in peroxides.
Explanation:
Color, the other answers arent changing the substance into something different
Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. when water is heated, the molecules gain energy and because of that, move faster. as they move faster, they come in contact with the sugar more often, causing it to dissolve faster.
