The electronegativity of nitrogen (N) is 3.0, while the electronegativity of hydrogen (H) is 2.1. As it can be seen that nitrogen (N) is more electronegative than that of hydrogen (H),
So electron pairs are attracted towards nitrogen and thus it carries a partial negative charge and hydrogen carries a partial positive charge. The image of electron distribution is attached as follows.
Thus NH₃ is a polar molecule .
Answer:
Imagine that x (ounce) is the amount of paint used to paint the flag
Base on the information, we know that:
2/3 + 3/5 + 2/15 + x = 2
x = 2 - 2/3 - 3/5 - 2/15
x = 30/15 - 10/15 - 9/15 - 2/15
x = 9/15 = 0.6 (ounce)
So the amount of paint used to paint the flag is 0.6 ounce.
Explanation:
I know only P2O5 = Phosphorus pentoxide
Answer:
The value of K at this temperature = 2.25
Explanation:
According to question the equilibrium reaction is
H₂(g) + I₂(g) ⇄ 2 HI(g)
Initial concentration 2 2 8
At equilibrium 2 + 2x 2 + 2x 8 - 2x
At equilibrium concentration of HI changes to become 6 Molar
So 8 - 2x = 6
or, x = 1
So concentration of H₂ = 2 + 2 x 1 = 4 molar
concentration of I₂ = 2 + 2 x 1 = 4 molar
Kc =
⇒ Kc =
⇒ Kc = = 2.25
The answer would be 19.3g/cm^3
Explanation: D=m V;D = 38.6g/2cm^3 = 19.3g/cm^3. Due to the chart, the unknown sample is gold. Gold is a soft metal that is malleable and ductile. It has a great density value, which makes it heavy metal.
P= 38.6/2 =19.3g/cm^3
