C + 2S → CS2 + 89.3 kJ
Moles of CS2 = 150.0 kJ x (1 mol CS2/89.3 kJ) = 1.680 mol CS2
MW of CS2 = (12.01 + 2x32.06) g/mol = 76.13 g/mol
Mass of CS2 = 1.680 mol CS2 × (76.13 g CS2/1 mol CS2) = 128 g CS2
The products and reactants weigh the same since u have to balance out the equation to have an equal number of molecules on bothsides
The physical and chemical properties of the dental braces would be listed and explained below.
<h3>What are dental braces?</h3>
Dental braces are the dental devices or tools that are used for correction of abnormally developed tooth.
Wearing of dental braces can help to permanently straighten the teeth.
The physical properties of dental braces include the following:
- they have abrasion and abrasion resistance
- they have thermal diffusivity and coefficient of thermal expansion.
The chemical properties of dental braces is that they are chemically inert leading to its ability to avoid any reaction with the wet (as well as low and high pH) environment of the mouth.
