The energy can be shown as:
Q = ms dT
Whereas, m is the mass of block
s is specific heat
dT is change in temperature.
Copper block having the lowest specific heat and thus having the higher change in temperature and therefore having the higher final temperature.
Answer:
The reaction is a double displacement reaction
Explanation:
Let us consider the reaction equation of the reaction between ammonium oxalate and lithium acetate.
(NH4)2C2O4(aq) +2 CH3COOLi(aq) -------> 2NH4CH3CO2(aq) + Li2C2O4(s)
This is a displacement reaction. A double displacement reaction is a type of reaction in which two reactants exchange their ions to form two new compounds. Double displacement reactions usually lead to the formation of a solid product which is also called a precipitate.
The general form of a Double displacement reaction is of the format:
AB + CD → AD + CB
Where A,B,C and D represents different ions respectively.
A double displacement reaction can also be referred to as salt metathesis reaction, double replacement reaction, exchange reaction, or a double decomposition reaction, although the latter term is more strictly used when one or more of the reactants does not dissolve in the solvent.

1. Make an observation
: My toaster doesn't toast my bread
2. Ask a question
: Why doesn't my toaster work?
3. Form a hypothesis
: My coffeemaker works when plugged into the outlet
4. Make a prediction
: If something is wrong with the outlet, then my coffeemaker also won't work when plugged into it
5. Conduct an experiment
: I plug my coffeemaker into the outlet
6. Analyze the results
: There is something wrong with the electrical outlet
Explanation:
The solution to the problem is as shown above.
- A scientific method follow a methodical way of critically carrying out an inquiry into an observation.
- Firstly, an observation is usually made with our senses. Here the researcher observes that the toaster does not toast his bread probably after a long wait.
- He then proceeds to ask why the toaster does not work.
- To investigate this, the forms a hypothesis. A hypothesis is a scientific guess. It is a tentative proposition about an investigation.
- The researcher then makes a prediction about the outlet that might be faulty.
- With this background, he goes on to carry out an experiment to substantiate his findings. This is seen when he plugs the coffeemaker into the outlet.
- From the analysis of result, he sees that that something is wrong with the outlet.
