Which formula represents a polar molecule? (1) Br2 (3) CH4 (2) CO2 (4) NH3

1 answer:

8 0

The formula representing a polar molecule is (4) NH3, for the difference in electronegativity of Nitrogen (N) and Hydrogen (H) is large, and thus it is polar.

Hope this helps~

Predict the effect of an eightfold pressure increase on the equilibriunm composition of the reaction 3 Nalg) + H21g) =2 NaHlg)

aniked [119]

According to Le cha telier's principle when we increase the pressure of a equilibrium reaction the reaction shift to the side where few moles of gas present.

Your reaction (Notice - I guess the reaction you written is wrong, but still I'm solving with your given prediction)

3NaI (g) + H2 (g) = 2NaHI (g)

Where access of sodium iodide is reacting with Hydrogen gas to form NaHI molecule.

Number of moles of gas on reaction side - 3+2 = 5 moles

Number of moles of gas on product side - 2 moles

Conclusion- the reaction will shift to the right of the reaction

Joe is concerned about the carbon dioxide emissions from his daily commute and the impact that it is having on global warming In

Vesna [10]

Amount of CO₂ emission per day is 11,356.23 g.

Explanation:

Joe travelling distance per day = 60 miles

Carbon dioxide emission per day = 20 mpg

Now we have to find the amount of carbon dioxide emitted per day by dividing the distance by the emission per day given in gallons.

Amount of Carbon dioxide emission = $$\frac{distance}{emission amount}$

Amount of CO₂ emission in gallons = $$\frac{ 60 miles}{20 mpg}$

= 3 gallons

Now we have to convert the gallons to grams as,

1 gallon = 3,785.41 g

3 gallons = 3 × 3785.41 g = 11,356.23 g

So the emission of CO₂ per day is 11,356.23 g.
