Answer:

Explanation:

Length: Length is a measure of distance

Height:The measurement from base to top or (of a standing person) from head to foot.

Circumference:The enclosing boundary of a curved geometric figure, especially a circle

Perimeter: Length of the outline of a shape.

Diagonal:A line segment that goes from one corner to another, but is not an edge. So when we directly join any two corners (called "vertices") which are not already joined by an edge, we get a diagonal. Diagonals of Polygons.

Diameter: A straight line passing from side to side of any figure or body, through its center.

what is the mass (in grams) of chlorine required to react with 10.0 g of sodium metal to produce sodium chloride?
Gnoma [55]

The mass of chlorine required to react with 10.0 g of sodium metal to produce sodium chloride is 15.26 g.

The balanced chemical reaction is :

<em>            2Na + Cl₂ → 2NaCl</em>

<em />

Given data :

Mass of sodium = 10.0 g

Number of moles of Na -

Number of moles = <u>  Given mass  </u>

                                    Molar mass

Number of moles = <u> 10.0 g</u> = 0.43 mol

                                  23 g

Comparing moles of Na and Cl₂ from the balanced chemical equation,

                                            Na        :        Cl₂

                                             2          :         1

                                             0.43     :        <u> 1 </u> x 0.43 = 0.215 mol

                                                                   2

Mass of chlorine gas :

          (molar mass of chlorine = 71 g)

Mass of chlorine = number of moles x molar mass

Mass = 0.215 mol x 71 g/mol

          = 15.26 g

The main reasons why ch4 has a higher vapor pressure at a given temperature when compared to ch3cl is that ch4 and . 2. the main
ale4655 [162]
Vapour pressure of system depends upon intermolecular forces of interaction. Greater the interaction, larger will the vapour pressure, more will be the boiling point.

Answer 1: 
CH4 stands for methane and CH3Cl named as chloromethane. In methane, all the valances of C atom is satisfied by hydrogen. Due to this, it has zero dipole moment. While, in case of CH3Cl, one of the valance is satisfied by an electronegative element i.e. Cl. Due to this, it acquires a polar character. Also, it has a net dipole moment. Due to this, CH3Cl exhibits dipole-dipole intermolecular force of attraction, which is absent in CH4.  Hence, CH3Cl has lower vapor pressure as compared to CH4. 

Answer 2: 
H2CO is named as formaldehyde, while CH3OH is named as methyl alcohol. In case of methyl alcohol, hydrogen atom (an electropositive atom) is bonded to oxygen (a highly electronegative element). This is absent in case of formaldehyde. Due the this, methyl alcohol as greater polarity as compared to formaldehyde. Due the greater polarity, vapour pressure of CH3OH is less as compared to H2CO. 

Answer 3:
<span>CH3CH2CH2OH is named as propanol or propyl alcohol. Propyl alcohol, has longer chain length as compared to methyl alcohol (CH3OH). Both of this compounds has a polar character due to presence of -OH functional group. However, due to long chain of propyl alcohol, polar character increases. This can be attributed the +I effect of CH3 group. Due to this, intermolecular forces of interaction are higher in propanol, thereby decreasing its vapor pressure as compared to methanol. </span>
