would precipitation occur when 500 ml of a 0.02 m solution of agno3 is mixed with 500ml of a 0.001M solution of nacl? explain
Black_prince [1.1K]
First, write the chemical equation that represents the chemical reation to state the products:

AgNO3 (aq)+ NaCl (aq) → AgCl (s)+ NaNO3 (aq)

The terms (aq) are used to indicate tha the compund is in aqueous solution, whle (s) is used to indicate a solid compound.

You can use the solubility rules or a table of solubilities to check solubilities of Ag Cl and NaNO3 in water. I used a table of solubilities. If  you do it you will find that NaNO3 is soluble in water and AgCl is insoluble. Then AgCl will form a precipitate.

Then, the answer is yes, precipitation of AgCl would occur.

There are ______ electrons, _______ protons, and ______ neutrons in an atom of .
Georgia [21]

There are 54 electrons, 54 protons, and 78 neutrons in an atom of 132 Xe.54.

Xenon is a chemical element with the symbol Xe and atomic number 54. It is a colourless, dense, odourless noble gas found in Earth's atmosphere in trace amounts.

Although generally unreactive, it can undergo a few chemical reactions such as the formation of xenon hexafluoroplatinate, the first noble gas compound to be synthesized.

Solid xenon changes from face-centred cubic (fcc) to hexagonal close packed (hcp) crystal phase under pressure and begins to turn metallic at about 140 GPa, with no noticeable volume change in the hcp phase. It is completely metallic at 155 GPa.

When metallized, xenon appears sky blue because it absorbs red light and transmits other visible frequencies. Such behaviour is unusual for a metal and is explained by the relatively small width of the electron bands in that state.

What was the purpose of varying the concentrations of sodium alginate and CaCl2?
jeka57 [31]

To determine how stable the beads are as well ensue the securing of maximum enzymes as well as the retention of their activity.

<h3>What is concentration?</h3>

The concentration of a substance simply means the amount of the substance in solution. Thus we are looking at the amounts of sodium alginate and CaCl2 in the system.

The concentrations of the sodium alginate and CaCl2 is varied in order to determine how stable the beads are as well ensue the securing of maximum enzymes as well as the retention of their activity.
