What will happen if a solution of sodium hydrocarbonate is heated give the equation of the reaction involved.

1 answer:

7 0

If heated, a decomposition reaction takes place. Sodium hydrocarbonate decompose to sodium carbonate, carbon(IV) oxide and water.

Balanced chemical equation of heating sodium bicarbonate:

2NaHCO₃ → Na₂CO₃ + CO₂ + H₂O

NaHCO₃ is sodium hydrocarbonate

Na₂CO₃ is sodium carbonate

CO₂ is carbon(IV) oxide

H₂O is water

This is chemical change (chemical reaction), because new substances are formed (sodium carbonate, carbon(IV) oxide and water), the atoms are rearranged, so there is no sodium bicarbonate (NaHCO₃) in the test tube.

Decomposition is reaction where one substance is broken down into two or more simpler substances.

Tell whether the statement is TRUE or FALSE. Air pressure is gravity pulling down on air molecules.

nirvana33 [79]

True
Pressure is the force per unit area on an object. The force in the case of air pressure is the weight of the air molecules; therefore, the air pressure is essentially due to gravity pulling down air molecules.

Identify the type of bonding within each substance. Co ( s ) ionic covalent metallic CoCl 2 ( s ) covalent ionic metallic CCl 4

krok68 [10]

Answer:

1. Co ( s ) - metallic bonding

2. CoCl₂ ( s ) - ionic bonding

3. CCl₄ ( l ) - covalent bonding

Explanation:

Metallic bonding -

It is the type of bonding present between the atoms of the metals , via the electrostatic interaction between the metal and the delocalized electrons , is known as metallic bonding .

For example ,

Mostly metals show metallic bonding .

Ionic bonding -

It is the type of bonding present between the ions i.e. , the cation and the anion is known as ionic bonding .

For example ,

Mostly ionic compound , like salts show ionic bonding .

Covalent bonding -

It is the type of bonding which is present between shared pair of electrons , is known as covalent bonding .

For example ,

Most of the carbon compounds are capable to show covalent bonding .

Hence , from the question ,

1. Co ( s ) - metallic bonding

2. CoCl₂ ( s ) - ionic bonding

3. CCl₄ ( l ) - covalent bonding

How would you know if this combination is likely to be found in dirt? Please explain!

Elan Coil [88]

No it is not likely. That is a ratio of 10:4 N^14 and N^15 which doesn’t work. It needs a higher amount
