Answer:
a) polytetrafluorethylene
b) polyethylene terepthalate
c) Nickel
d) Polytetrafluroethylene
e) Aluminum
Explanation:
a) polytetrafluorethylene can be used to make laboratory bottles that can contain nitric acids ( dilute ones ) because of its resistance to either acidic or basic solution
b) polyethylene terepthalate can be used because it is relatively cheaper, also Benzene doesn't exhibit corrosion effect
c) Nickel can be used to produce pipes that transport hot alkaline solutions
d) Polytetrafluroethylene can be used for underground water tanks
e) Aluminum is used because it is light weighted and exhibits corrosion resistivity to climate change
Q. What is the mass in grams of one mole of any substance know as
A. Molar Mass
Each bundle of nerve fibers is called a fasciculus and is surrounded by a layer of connective tissue called the perineurium.
Answer:
1. right 2. left 3. left 4. left 5. left
Explanation:
1. N2 is a reactant, so adding more will push the reaction away from N2 which will be right, towards the products
2. treat heat as a product, so by increasing temp you increase heat and you push the reaction away from heat which will be left, towards the reactants
3. Adding NH3 will push the reaction away from it, so it'll move left, towards reactants
4. When you decrease pressure, the reaction will move to the side with more moles, since the left side has 4 moles and the right only has 2, it'll move left
5. by removing H2, the equillibrium will shift left in order to restore balance.
