Answer:

Kindly check the explanation section.

Explanation:

PS: Note that enough information are not being provided and we do not know the experiment this question is all about. However, some information are provided below which is going to aid in solving when you get access to the main question.

The determination of the heat transferred from one substance to another is one of the important aspect in science. The method in which this heat is being measured is known as calorimetry and the instrument used in this technique is known as the calorimeter.

When the energy content of a snack is needed to be calculated, there is the need use a type of instrument known as bomb calorimeter.

Most of the calorimeters used by students are not so expensive like the used in the industries. Most of these calorimeters operates at a constant pressure while the Bomb Calorimeter operates at constant volume.

What factor is most responsible for the fact that water is a liquid rather than a gas at room temperature?
ivann1987 [24]
The factor that is most responsible for the fact that water is a liquid rather than gas at room temperature is the hydrogen bonding. The hydrogen bonding keeps the water molecules bonded together, otherwise it would have been in a gaseous state. I hope the answer helps you.

Why is the mixture of the titration of potassium permanganate solution using oxalic acid heated before titration? ​
alexgriva [62]

Explanation:

During titration of oxalic acid and KMnO_4 in acid medium to reaction is extremely slow. SinceKMnO_4 is acting as a self indicator the colour disappears after less than 30s even after approaching equivalent point. So the reaction mixture is heated to approximately 70–80^0 C (just before it starts boiling) and the titration is started. This helps in initiating the reaction via supplying the necessary activation energy of the reaction.  Secondly the heat helps to decompose [Mn(C_2O_4)^3]^{-3}complex which forms as a result of local excess of KMnO_4.the complex is unstable above 60^0C and the Mn^{+2} formed as a result catalyses the rest of the reaction. Thirdly the temp should never exceed the range given as oxalic acid will decompose above this temp to Co_2

Inferring conclusions if you find an element in nature in its pure elemental state what can you infer about the elements chemica
Grace [21]

Answer;

-Not that reactive

The element found is not very reactive.

Explanation;

-If an element is found in nature in its pure elemental state then the the element found is not very reactive.

-There are many elements which are not much reactive. such as in metals- Ag, Au, Hg, Cu etc. and in Non metals- O2, N2, Inert gases etc.

- For checking its chemical properties you will have to examine it with O2 or C-12.
