For the Lewis diagram of the cyanide ion, a
figure is shown.<span>
There are 3 pairs of bonding electrons. There is a
one lone pair each for the carbon and the nitrogen atoms.</span>
<span>I hope I was able to answer your question. Thank
you!</span>
Answer;
Ar (Argon)
Explanation;
-S (Sulfur) atom has 16 electrons, however it forms an anion (negatively charged ion) by gaining two electrons. Therefore; S^2- has 18 electrons. In other words it requires two electrons to form a stable configuration or an octet configuration.
-Argon (Ar) is a noble gas (group 8 element) which means it has an octet configuration. It has 18 electrons similar to an ion of sulfur (S^2-).
WHILE ARRANGING THE ELEMENTS, NEWLAND OBSERVED THAT ORDER HE SET WERE LIKE NOTES REPRESENTED AS THE SIGNS,THAT IS, EVERY FIRST NOTE IS EQUAL TO THE EIGHT ELEMENT, BUT HE COULD FIND ONLY 58 ELEMENTS THAT WERE CORRECTLY ORDERED IN HIS TABLE
Answer : The moles of sucrose used in the recipe are, 1.11 moles.
Explanation : Given,
Mass of sucrose = 380 g
Formula used :
Molar mass of sucrose = 342.3 g/mole
Now put all the given values in the above formula, we get:
Therefore, the moles of sucrose used in the recipe are, 1.11 moles.
Al species is oxidized in the reaction below al2o3(s) 3 co(g) → 2 al(s) 3 co2(g by oxidation
The reaction brought on by coming into touch with oxygen molecules is known as oxidation. These materials can be non-metals like live tissues or metals. Technically speaking, oxidation is the loss of one electron during the phase of interaction between two or more atoms.
Initially, the word "oxidation" was used to refer to chemical processes in which an element reacts with oxygen. An illustration of this is the oxidation of magnesium in the formation of magnesium oxide when magnesium metal and oxygen react.
The biological oxygen demand (BOD) of wastewater is decreased after oxidation, which also lessens some contaminants' toxicity. Some contaminants undergo this treatment and are transformed into carbon dioxide, water, and biosolids. Disinfection is commonly accomplished using chemical oxidation.
