Carbon dioxide non examples? Please and catalyst non examples?

Chemistry
1 answer:
PilotLPTM [1.2K]3 years ago
5 0

Answer:

I guess you mean by non element example. Non element examples have more than one elements. Carbon dioxide is a non element example since caebon dioxide has 2 oxygen atoms + 1 carbon atom = carbon dioxide.

I think catalyst is also a non element example because catalyst is inorganic which means that it is not a living thing. Since catalyst is in brass and brass is a non element example, I think catalyst is also a non element example.

Hope that helps, thank you !!

Write the formula for a complex formed between zn2 zn2 and nh3nh3 with a coordination number of 3.
fredd [130]

Triammine zinc sulfate is the formula for a compound produced between zn2 and nh3 with a coordination number of 3.

<h3>Steps</h3>

Zinc atoms are present in the +2 oxidation state in zinc sulfate (ZnSO4).

Thus, a coordination complex formed by three ammonia ligands and zinc sulfate can be shown below.

NH3 + ZnSO4 = [Zn(NH3)] SO4

In its ionic form, this equation can be expressed as

Zn²⁺ + 3NH₃ = [Zn(NH₃)₃]²⁺

<h3>Coordination number: what is it?</h3>

The number of atoms, ions, or molecules that a central atom or ion in a complex, coordination compound, or crystal holds as its closest neighbors.

<h3>What is a good illustration of a coordination number?</h3>

For instance, [Cr(NH3)2Cl2Br2] has the core cation Cr3+, which is referred to as hexacoordinate and has a coordination number of 6.

Calculate the percent ionization in each of the following solutions. (a) 0.10 M NH3 WebAssign will check your answer for the cor
Sergeeva-Olga [200]

Answer:

Dissociation NH3 0.10 M : 1.2%

Dissociation NH3 0.010 M : 3.9%  

Dissociation CH3NH2 0.10 M : 6.5%

Explanation:

Hello!

To calculate the percentage of dissociation it is necessary:

Pose the balanced chemical equation.

Pose the equilibrium constant.

Calculate the value of "x"

Calculate the percentage of dissociation.

By having the concentrations given two significant figures we express the dissociations with the same amount of significant figures.

Successes with your homework!

How many significant figures is in 1234
DENIUS [597]

Answer:

4 significant figures.

Explanation:

The given measurement have four significant figures 1234.

All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.

Leading zeros are not consider as a significant figures. e.g. 0.03 in this number only one significant figure present which is 3.

Zero between the non zero digits are consider significant like 104 consist of three significant figures.

The zeros at the right side e.g 2400 are also significant. There are four significant figures are present.
