Reactivity could be one also toxicity flammability ect
Answer:
Examples of solids that sublime are dry ice (solid carbon dioxide), iodine, arsenic, and naphthalene (the stuff mothballs are made of).
Explanation:
Answer:
Carbon products are obtained by heating coal (to give coke), natural gas (to give blacks), or carbonaceous material of vegetable or animal origin, such as wood or bone (to give charcoal), at elevated temperatures in the presence of insufficient oxygen to allow combustion.

Answer:
Assuming Volume of dolution = 1 liter . The Normality is:

Explanation:
<u>Normality : </u>It is the gram equivalent of solute per liter of solution. It is represented by N.

Number of equivalents weight =

n= acidity of base or basicity of acid
for salts , n = charge present on cation
The relation between Normality and Molarity is :

n = charge present on cation (<u>not moles)</u>
= ferric sulphate
Here <u><em>Fe is cation and its oxidation state is = + 3 so n= 3</em></u>
1. First , calculate the molarity(M)
Molar Mass of ferric sulfate = Fe2(SO4)3
2(mass of Fe)+3 (mass of S) + 12(mass of O)
= 2(56)+3(32)+12(16)
= 400 grams


Molar mass = 400 gram
mass = 50 mg = 0.05 grams



let volume = 1 liter


<u><em>2. Multiply the molarity with n </em></u>


n = 3
