Answer:

3

Explanation:

The unbalanced combustion reaction of the oxidation of propane is shown below as:-

C_3H_8+O_2\rightarrow CO_2+H_2O

On the left hand side,

There are 3 carbon atoms and 8 hydrogen atoms and 2 oxygen atoms

On the right hand side,

There are 1 carbon atom and 2 hydrogen atoms and 3 oxygen atoms

Thus,

Right side, CO_2 must be multiplied by 3 and H_2O by 4 so to balance carbon and hydrogen.

Left side, O_2 is multiplied by 5 so to balance the whole reaction.

Thus, the balanced reaction is:-

C_3H_8+5O_2\rightarrow 3CO_2+4H_2O

<u>Coefficient in front of the carbon dioxide in the balanced equation - 3</u>

How Could Spectroscopy Be Used to Distinguish Between the Following
skelet666 [1.2K]

Spectroscopy be used to distinguish between the following is the compound B has a peak at 3200 – 3500 cm⁻¹ in its IR spectrum.

<h3>What is spectroscopy?</h3>

Spectroscopy is the study of emission or absorption of light. It is used to study the structure of atoms and molecules.

The three types of spectroscopy are:

  • atomic absorption spectroscopy (AAS)
  • atomic emission spectroscopy (AES)
  • atomic fluorescence spectroscopy (AFS)

Thus, the correct option is B, the compound B has a peak at 3200 – 3500 cm⁻¹ in its IR spectrum.

11. Which of the following is a characteristic of all chemical changes? *
Shtirlitz [24]

Answer:

Explanation:

A new Material is formed.

Basically, Chemical changes differ from Physical changes because in chemical changes, Substances have the ability to become a different substance.

Example:

Water to ice is a physical change because it is still water despite being a solid from liquid.

A Magnesium strip placed in CuSO4 solution made the Mg strip turn into a new substance which is MgSO4. this is a Chemical change because Mg has now become a different substance called MgSO4.

What is the function of a mordant in gram staining?
Anna71 [15]
The  function  of  mordant  in  the   gram  staining  is  to   expose  grams  positive  cell  to  the  decolorizer  which  dissolves  the  lipids  in  the  cell  wall   thus  allowing  the  crystals  violent-iodine  to  leach  out  of  the  cell. This  facilitate  the  cell  subsequently   be  stained  by  with  safranin.
