Answer: A COMPLEX ION contains (a central metal ion bound to one or more ligands).

Explanation: A complex ion is defined as an ion that is formed between a central metal ion and one or more surrounding ligands, molecules or ions that contain at least one lone pair of electrons. The formation of a complex ion from a metal ion and a ligand is based on Lewis acid - base reaction. The positively charged metal ion( example Cu2+) acts as a Lewis acid, and the ligand, with one or more lone pairs of electrons (example NH3), acts as a Lewis base.

An example of a complex ion is copper ammine ion,{[Cu(NH3)6]2+}.

Answer:

A complex ion contains a central metal ion bound to one or more ligands

Explanation:

A complex ion is consists of a central atom or ion, that is usually metallic, called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents.

An example of a complex ion is

[Co(NH3)6]3+

Please go through the attached file for a proper representation of the complex ion.

Given that a theoretical yield for isolating Calcium Carbonate in this experiment would be 100%. From that information and based
Stels [109]

Answer:

It's well Explained below.

Explanation:

First of Excess product of CaCO_3 would be produced due to the fact that there would not be enough CaCl_2 to react with Na_2•CO_3. The main purpose of having stoichiometric quantities is for us to know the correct amount or near the correct amount of each reactant in order to create a product that will be close to the theoretical amount and thus have a higher percent yield.

PLEASE HELP!!!!! WILL MARK AS BRAINLIEST!!!!! What is the volume of 15.0 grams of H2S at STP?
ICE Princess25 [194]

Answer:

 The volume of 15.0 grams of H2S at STP is 9.85 L.

Explanation:

1 unit of any gas under STP has volume 22.4 L.

Unit's mass M(H2S) = 2M(H) + M(S)= 2*1.0 +32.1=34.1 g/U

15g * 1U/34.1g= 0.440 U

0.440 U*1L/22.4L= 9.85 L 

Hope this helped you :)

Good Luck :D

BTW, If you understand what I am saying and want the more technical answer, take all the (U) and replace it with (Mol) which is an abbreviation for Mole

:D have a good rest of your night
