Two factors that determine whether a molecule is polar are the types of atoms in the molecule and the SHAPE of the molecule.

A polar molecule is a molecule with two opposing charges, one end of the molecule has a partial negative charge while the other end has a partial positive charge. This occurs because the molecule is not totally symmetric. The polarity of a substance is typically determined by the characteristics of its constituent atoms and the shape of the molecule. Polar molecules are usually bent or trigonal in shape.

At high pressures and moderate temperatures nitric oxide gas disproportionates rapidly according to the reaction 3NO(g) ⇌ N2O(g)
Pie

Answer:

3.8 x 10⁵

Explanation:

For the equilibrium :  3NO(g) ⇌ N2O(g) + NO2(g), the equilibrium constant in the terms of the concentrations of the gases in mol/L is

Kc = (NO) (N2O)/ (NO) ³   where (NO), (N2O) , (NO2) are the concentrations of the gases in mol/L . So

K= (x mol/ 1 L) (x mol/1L) / (7.5 x 10⁻⁶ mol /1 L) ³

x  = mol of NO and NO2 at equilibrium

we have that

K = x²/ 7.5 x 10⁻⁶ = 1.9 x 10¹⁶

x = √ (7.5 x 10⁻⁶ x  1.9 x 10¹⁶) = 3.8 x 10⁵

∴ (N2O) = 3.8 x 10⁵

A chemist prepares a solution of aluminum sulfite by measuring out 109 umol of aluminum sulfite into a 350 mL volumetric flask a
Lelu [443]

Answer:

0.311 mmol/L

Explanation:

109  μmol = 109*10^(-6) mol

109*10^(-6) mol = 109*10^(-6) mol*(10^3 mmol/1mol) = 109*10^(-3) mmol =

=0.109 mmol

350 mL = 0.350 L

0.109 mmol/0.350 L = 0.311 mmol/L

Valence electrons determine an atom’s __________. a. mass c. atomic number b. chemical properties d. period
poizon [28]
Hey there !

Answer B

Chemical properties are characteristic behaviors of a substance when it is found in the presence of another substance. To investigate chemical properties we will have to carry out chemical transformations (performing chemical tests) and it is generally not possible to recover the sample used (because it suffers changes giving rise to other substances).
