Ethyl butyrate is also more commonly known as the ethyl butanoate with chemical formula of C₆H₁₂O₂. The equation of the butanoic acid (C₄H₈O₂) and ethanol (C₂H₆O) to form this substance can be written off as,
C₄H₈O₂ + C₂H₆O --> C₆H₁₂O₂ + H₂O
Note that the given equation is already balanced. Using dimensional analysis and conversion factors,
(8.5 g C₄H₈O₂)(1 mol/88.11 g)(1 mol C₆H₁₂O₂/1 mol C₄H₈O₂)(116.16 g / mol)
= 112.06 grams of ethyl butyrate
ANSWER: 112. 06 grams
Answer:
it will probably flame up or explode or maybe start boiling
Forming a hypothesis
Explanation:
The step in an investigation which involves the prediction of results is the stage of forming of a hypothesis.
- A hypothesis is a stage in scientific investigation that follows shortly after asking a simple scientific question.
- Hypothesis is simply a scientific guess that is logical in nature.
- It presents a problem in a manner in which the problem is stated, the cause and the likely outcome can be predicted.
- After a hypothesis formulation, the experiment is conducted and results of findings weighed against the predictions of the statement.

Answer : The precipitate will not be formed when these solutions are mixed.
Explanation :
The chemical equation for the reaction of calcium chloride and lithium sulfate follows:
We are given:
Concentration of calcium ion =
Concentration of sulfate ion =
The salt produced is calcium sulfate.
The equation follows:
The expression of (ionic product) for above equation follows:
Putting values of the concentrations in above expression, we get:
There are 3 conditions:
- When ; the reaction is product favored. (No precipitation)
- When ; the reaction is reactant favored. (Precipitation)
- When ; the reaction is in equilibrium. (Sparingly soluble)
As, the . The above reaction is product favored. This means that no salt or precipitate will be formed.
Hence, the precipitate will not be formed when these solutions are mixed.
Answer:
The temperature is the same overtime.
Explanation:
Since the line on the graph is straight the temperature will be constant.
