what’s the chemical equation for production of potassium vapor and molten sodium chloride from molten potassium chloride and mol

elena-14-01-66 [18.8K]

Answer:

$\huge\boxed{\sf KCl_{(aq)}+Na_{(aq)} \longrightarrow K_{(l)}+NaCl_{(aq)}}$

Explanation:

Chemical formulas for every compound:

Potassium vapor => $K_{(l)$

Molten soldium chloride => $NaCl_{(aq)}$

Molten Potassium chloride => $KCl_{(aq)}$

Molten Sodium Metal => $Na_{(aq)}$

The reaction will be as follows:

$KCl_{(aq)}+Na_{(aq)} \longrightarrow K_{(l)}+NaCl_{(aq)}$

This reaction is usually called displacement reaction in which an element displaces another element of a compund.

How can you experimentally determine the solubility of a solute in water at a certain temperature?

Veronika [31]

The solubility of a given solute in a given solvent typically depends on temperature. Many salts show a large increase in solubility with temperature. ... A few, such as cerium(III) sulfate, become less soluble in water as temperature increases.

Is usually categorized to a specific area in the state known as a soil series

Vikentia [17]

Answer:

Soil series as established by the National Cooperative Soil Survey of the United States Department of Agriculture (USDA) Natural Resources Conservation Service are a level of classification in the USDA Soil Taxonomy classification system hierarchy. The actual object of classification is the so-called soil individual, or pedon.[1] Soil series consist of pedons that are grouped together because of their similar pedogenesis, soil chemistry, and physical properties. More specifically, each series consists of pedons having soil horizons that are similar in soil color, soil texture, soil structure, soil pH, consistence, mineral and chemical composition, and arrangement in the soil profile.[2] These result in soils which perform similarly for land use purposes.

Classify methanal according to the position of the c=o group

seraphim [82]

Answer : Methanal also known as Formaldehyde $CH_{2}O$ is a chemical Aldehyde which contain ( -CHO) group.

Explanation :

In organic chemistry, a carbonyl group is a functional group which contain a carbon atom double-bonded to an oxygen atom i.e, ( C=O).

If carbonyl group is present in a compound then it can be a carboxylic (RCOOH), aldehyde (RCHO), ketone (RCOR'), ester ((RCOOR') or amide (RCONR'R") group.

Here are some functional groups naming according to the IUPAC rules and image also attached,

Carboxylic acid → (RCOOH) → ( name end in 'OIC ACID' )

Aldehyde → (RCOH) → ( name end in 'AL' )

Ketone → (RCOR') → ( name end in 'ONE' )

Ester → (RCOOR') → ( name end in 'ATE' )

Amide → (RCONR'R") → ( name end in 'AMIDE' )

In an aldehyde, atleast one hydrogen atom must be attached to the carbonyl carbon. For an aldehyde, remove ( -e) from alkane name and add ( -al) at the end of the compound.

Methanal is the IUPAC name for Formaldehyde.
