Iodine hexafluoride is the chemical name
Chemical reactions can be identified when there is a change in color, energy is produced, change in odor, or if new substance forms.
The mass number of aluminium hydroxide is 78 thus, the number of moles in 0.745 g is:
no. of moles= mass/ RFM
= 0.745/78
=0.00955moles
Therefore the 0.00955 moles should be in the 35.18 ml
therefore 1000ml of the solution will have:
(0.00955ml×1000ml)/35.18
=0.2715moles
The solution will be 0.27M hydrochloric acid
The answer is TRUE.
Energy is an extensive property, which means that it is in proportion to the amount of matter: more mass, more energy.
You can measure, for example, the internal energy per mol or per gram of several compounds or elements. then if you want to know the total internal energy of the system you have to multiply by the number of moles or grams, depending on the unit of the internal energy that you use.
