Answer:
Aluminum Gallium Reaction- Gallium reacts with Aluminum to create an Aluminum alloy that crumbles at the touch. Gallium attacks many metals including Aluminum & Steel by diffusing into the grain boundaries making them extremely brittle. Gallium easily alloys with many metals in low quantities
Explanation:
During all chemical reactions, the mass of the products is never equal to the mass of the reactants.
- FALSE
Mass is sometimes lost in chemical reactions.
- FALSE
The Law of Conservation of Mass states that mass is not conserved.
- FALSE
Answer: True
Explanation:
Titration is a quantitative technique where a solution of known concentration is used to determine the concentration of an unknown solution. The titrant (the known solution) is added from a burette to a known quantity of the the unknown solution until the reaction is complete.
By knowing the volume of titrant, we can determine the concentration of the unknown.
Thus the statement Titrations provide a method of quantitatively measuring the concentration of an unknown solution is True .
Answer:
7.3 mole
Explanation:
1 C6H10S gives 10H
0.73 mole of C6H10S gives X mole of Hydrogen
X= 0.73×10=7.3mole
Your answer will be 8942.5
