How many of the following molecules have sp2 hybridization on the central atom? hcn so2 ocl2 xecl2.
GrogVix [38]

Only one molecule have <u>sp2 </u>hybridization on central atom and that is <u>SO₂</u>.

<u>XeCl₂</u> have <u>sp3d </u>hybridization.

<u>OCl₂</u> have <u>sp3 </u>hybridization.

<u>HCN </u>have <u>sp </u>hybridization.

Hybridization is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals.

Hybridization intermixing usually results in the formation of hybrid orbitals having entirely different energies, shapes, etc.

A jeweler is making sapphire rings using 2 sapphires on every 1 ring. If the jeweler has 12 sapphires and 10 rings, what is the
user100 [1]

Answer: The theoretical yield is 6 rings.

Explanation:

Theoretical yield is predicted or estimated value.

Jeweler used 2 sapphires for 1 ring

Then for each sapphire there will be = \frac{1}{2} rings are used

For 12 sapphire = \frac{1}{2}\times 12=6 rings will be used

Out of 10 rings 6 rings with 2 sapphires will be made.

The theoretical yield is 6 rings.

What is the mass of a titanium alloy that has a heat of fusion of 422.5 joules/gram and requires 2.960 joules of energy to melt
7nadin3 [17]

Answer:

7.01 g

Explanation:

Answer:- Mass of the titanium alloy is 7.01 g, choice C is correct.

Solution:- The heat of fusion is given as 422.5 joules per gram and it also says that 2960 joules of heat is required to melt the metal completely.

The suggested equation is,  Q=mHf

where Q is the heat energy, m is the mass and Hf is the heat of fusion.

Since, we are asked to calculate the mass, the equation could be written as:

m=q/H5

Let's plug in the values in it:

m= 2960J/ 422.5j/g

m = 7.01 g

So, the mass of the titanium alloy is 7.01 g, choice C is correct.
