Given what we know, we can confirm that the amount of heat energy that would be required in order to boil 5.05g of water is that of 11.4kJ of heat.
<h3>Why does it take this much energy to boil the water?</h3>
We arrive at this number by taking into account the energy needed to boil 1g of water to its vaporization point. This results in the use of 2260 J of heat energy. We then take this number and multiply it by the total grams of water being heated, in this case, 5.05g, which gives us our answer of 11.4 kJ of energy required.
Therefore, we can confirm that the amount of heat energy that would be required in order to boil 5.05g of water is that of 11.4kJ of heat.

The answer is true. It is the last star.
Answer:
0.00246kg
Explanation:
1g = $40.63
$100 = $100/40.63 = 2.46g
2.46/1000 g = 0.00246kg
It is important to compare the positive and negative test results with those of known compounds as positive results indicate the presence of that known compound and negative results indicate the absence of that compound which is used for reference.
<h3>What is qualitative analysis?</h3>
Qualitative chemical analysis is a method to determine the chemical composition of a sample.
There are two types of qualitative analysis:
- Organic Qualitative analysis: It helps in determining the chemical bonds and functional groups in a sample
- Inorganic qualitative analysis: It helps in determining the ions in the given sample
There are seven ways to analyze a sample qualitatively, which are
A reference compound is always used to which results are compared.
A Positive result indicates that the reference compound is present in the sample whereas a negative result indicates that the reference compound is absent in the given sample.
