H2, N2, O2 molecules. . . A)must be polar. must be nonpolar. . B)can be polar or nonpolar depending on geometric . C)configurati
LenKa [72]

Answer: The correct option is A.

Explanation: The given molecules are the molecules of same element.

These molecules are considered as diatomic species.

Polar molecules are the molecules in which some polarity is present in the bond. These molecules are formed when there is some difference in the electronegativities of the elements. Example: HCl

Non-polar molecules are the molecules where no polarity is present in the bond. These molecules are formed when there is no difference in the electronegativities of the elements. Example: H_2, O_2

The given molecules are non-polar in nature.

Hence, these molecules must be non-polar. So, the correct option is A.

What will the volume of a 3.8 M solution be if it contains 4.9 grams of calcium hydroxide?
Mekhanik [1.2K]

Answer:

no of moles = <u>volume in cm3 x concentration in</u> <u>mol/dm3 or M </u>

1000

no of moles =<u> mass</u>

molar mass

<u>mass</u>

molar mass =<u> vol x con</u>

1000

molar mass of ca(oh)2 = 74 g/mol

<u>4.9</u><u> </u><u>=</u><u> </u><u>vol</u><u> </u><u>x</u><u> </u><u>3</u><u>.</u><u>8</u><u> </u>

74. 1000

= 17.42 g

Identitfy the types of reaction:
Vera_Pavlovna [14]

Answer:

C2H5OH + Na = C2H5ONa + H2 - Single replacement reaction

AgCl + HNO3 = AgNO3 + HC - Double replacement reaction

N2 + H2 = NH3 - Combination reaction

MgCO3 = MgO + CO2  - Decomposition reaction

Explanation:

<u>Single replacement reaction</u> - The type of reaction in which one strong ion replaces the weak ion from the solution.

For example: C2H5OH + Na = C2H5ONa + H2

<u>Double replacement reaction </u>- The reaction in which two compounds in a solution reacts by interchanging their ions and forms a new product.

For example: AgCl + HNO3 = AgNO3 + HCl

<u>Combination reaction</u> - The type of reaction in which two or more compounds combine together to form a single compound.

For example: N2 + H2 = NH3

<u>Decomposition reaction</u> - The type of reaction in which only one compounds break down into two or more new compounds.

For example: MgCO3 = MgO + CO2

Hence, the correct answer is:

C2H5OH + Na = C2H5ONa + H2 - Single replacement reaction

AgCl + HNO3 = AgNO3 + HC - Double replacement reaction

N2 + H2 = NH3 - Combination reaction

MgCO3 = MgO + CO2  - Decomposition reaction
