Plastic is endothermic because plastic can melt
Answer:
3.00 × 10²³ atoms H
Explanation:
Step 1: Given data
- Atoms of oxygen in water: 1.50 × 10²³ atoms
- Chemical formula of water: H₂O
Step 2: Calculate the number of atoms of hydrogen
According to the chemical formula of water, the atom ratio of H to O is 2:1.
1.50 × 10²³ atoms O × 2 atoms H/1 atom O = 3.00 × 10²³ atoms H
A.movement and protection
The solution is a weak base. a weak base is that which dissociates partially in aqueous solution to give hydroxide ions as the only negatively charged ions. In the provided information, only 32 %of the substance dissociates thus it is a partial dissociation. Most of the energy is used to break bonds thus the remaining energy is not enough to cause complete dissociation.
Answer:
14.048 moles I believe.
Explanation:
(8.46 * 10^24) / ( 6.022 * 10^23) = 14.048
