Household baking soda has the chemical formula nahco 3 . name the elements in baking soda. use the periodic table (given in last lesson) if necessary: chlorine nitrogen hydrogen helium carbon oxygen sodium

Sodium

Hydrogen

Carbon

Oxygen

Explanation:

Formula of baking soda is NaHCO₃. It is the salt consist of sodium (Na⁺) cation and bicarbonate (HCO₃⁻) anion. It is also called sodium hydrogen carbonate. It is crystalline white solid.

Elements in baking soda:

Sodium:

Sodium is present in third period and group one of periodic table. It is eleventh element of periodic table. It is alkali metal and lose one valance electron thus carry +1 charge.

Hydrogen:

It is first element of periodic table. Its atomic number is one and mass is 1.008 g/mol. It can lose its one electron and has +1 charge.

Carbon:

It is present in the group fourteen of periodic table. It can lose its four valance electrons and form four covalent bonds. Its atomic number is six and atomic weight is twelve.

Oxygen:

It is the eighth element of periodic table. It is present in group sixteen and second period of periodic table. It has six valance electrons. It is also called chalcogen because it is ore forming element.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.

explanation:

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
