Explanation:
Molecular mass of NO2= 14+16×2=46
1 mole NO2 = 46 gm of NO2
9.4 moles of NO2= 46×9.4 gm= 432.4 gm NO2.
Answer:
the answer is 25.032g check pic for explanation
Answer:
Yes
Explanation:
It is frequently quoted that upwards of 80% of our taste is made up by smell. So if you plug your nose and cover your eyes, the taste between an apple and onion should be indistinguishable. The logic makes sense. ... All potato chip flavors taste the same.
Answer: HCl
Explanation:
Br₂ is a diatomic molecule meaning that there are no permanent dipole-dipole forces between these two. There are VDW forces between each molecule but these are weak as they are not differing in electronegativities, so this is not the answer.
Ne is a single element, there are no attractive forces.
N₂ is also a diatomic molecule, and for the same reasons as Br₂ it is also not the answer.
Between HCl and HBr, HCl has a greater electronegativity difference.
This is because on the electronegativity scale, H is 2.1, Cl is 3.0, and Br is 2.8. Make sure to refer to the Pauling electronegativity scale for these types of questions - you may be required to just remember that certain values are higher than others (the most electronegative elements on the periodic table are the futherest up and right - so the most electronegative element is fluorine).
As H and Cl have the greatest electronegativity difference, they have the largest dipole-dipole forces.
