Answer:
AgNO₃ will be the limiting reagent.
Explanation:
The balanced reaction is:
AgNO₃ + Li → LiNO₃ + Ag
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate:
- AgNO₃: 1 mole
- Li: 1 mole
- LiNO₃: 1 mole
- Ag: 1 mole
To determine the limiting reagent, you can use a simple rule of three as follows: if by stoichiometry AgNO₃, how much moles of AgNO₃ will be needed if 0.35 moles of Li react?
moles of AgNO₃= 0.35
But 0.35 moles of AgNO₃ are not available, 0.30 moles are available. Since you have less moles than you need to react with 0.35 moles of Li, <u><em>AgNO₃ will be the limiting reagent.

2. This question has two parts. First, answer
Part A. Then, answer Part B. Part A
In Passage 2, what theme is suggested by Graham’s situation?
D People will do whatever is necessary to keep what is important to them.
Part B
Which quotation helps develop the theme in Part A?
D “Graham turned to the old man and asked, ‘How are we going to find it?’” (paragraph 25)
Part A
Option D: This answer is correct. The man agrees to the risky proposition to search for buried treasure since it seems to be the only way for him to keep his family's property.
Part B
Option D: This answer is correct. This quotation shows that Graham is considering the man's proposition to look for buried treasure in the hopes of keeping his family's property
Answer:
the most common is 'direct combustion'.
Elements in the same group tend to have very similar properties (D). This is due to the number of valence electrons each group has.
Answer:
Explanation:
The specific heats of water and steel are
Assuming that the water and steel are into an <em>adiabatic calorimeter</em> (there's no heat transferred to the enviroment), the temperature of both is identical when the system gets to the equilibrium
An energy balance can be written as
Replacing
Then, the temperature
