Iodine pentafluoride reacts slowly with glass and violently with water. determine its molecular mass.
pickupchik [31]
<h3>Answer:</h3>

               221.90 g.mol⁻¹

<h3>Explanation:</h3>

                          The mass of contained by a molecule is known as molecular mass. It is the sum of atomic weights of the elements contained by the molecule. In given case Iodine Pentafluoride has a chemical formula,

                                                          IF₅

The atomic weights of each element are as;

                                        Iodine  =  126.90 g.mol⁻¹

                                        Fluorine  =  19.00 g.mol⁻¹

As there are five atoms of Fluorine so, we will multiply the atomic weight of Fluorine by five and that of Iodine by one as there is only one Iodine atom.

Therefore,

         Molecular Mass of IF₅  =  (1 × 126.90 g.mol⁻¹) + (5 × 19.00 g.mol⁻¹)

         Molecular Mass of IF₅  =  (126.90 g.mol⁻¹) + (95.00 g.mol⁻¹)

         Molecular Mass of IF₅  =  221.90 g.mol⁻¹

Acetaldehyde is a substance commonly used in chemical factories. It is often produced by
Eduardwww [97]

There are 48 hydrogen atoms,  24 carbon atoms, and 12 oxygen atoms, also 12 molecules of acetaldehyde were produced in the reaction.

The equation of the reaction is;

12C2H4 + 6O2 ------> 12 CH3CHO

In order to approach this problem, the balanced reaction equation is the first step. There are 12 ethylene molecules and six oxygen molecules. These will combine as shown.

There number of atoms involved are as follows;

H = 48

C = 24

O = 12

There are 12 molecules of acetaldehyde produced in the reaction.

Explain what happens to the light ray when it travels through air and then into water
NemiM [27]

A Change of Course. Light travels faster through air than it does through a denser substance, such as water or glass.

So, when light rays travel through air and meet the surface of the denser substance, they are suddenly slowed down.

When this happens, the light rays bend.
