Answer:
The container that has 0.20 moles of the compound has more moles compared to the container that has 0.15 moles of compound A
Explanation:
The molarity is defined as the concentration of a substance in solution, expressed as the number of moles of a solute per liter of solution.
From the given information.
In compound A
Molarity of the solution = 0.15 molar = 0.15 m/L
It implies that, In compound A, there are 0.15 moles present in 1 L of the solution.
Similarly;
In compound B
Molarity of the solution = 0.20 molar = 0.20 m/L
It implies that, In compound B, there are 0.120 moles present in 1 L of the solution.
Thus, we can conclude that:
The container that has 0.20 moles of the compound has more moles compared to the container that has 0.15 moles of compound A
I believe the answer is C !
Answer:
Based on these values and on consideration of molecular geometry, the H-Se bond can be considered almost _____non-polar___ and the molecule is __polar_____.
Explanation:
Looking at the difference in electro negativity of the two elements; hydrogen and selenium, one may be led to the conclusion that the molecule is nonpolar since the magnitude of electronegative between the two bonding atoms is minimal.
However, electro negativity difference alone is insufficient to determine the polarity of a molecule. The structure of the molecule is also considered. Based on the structure of the molecule, it is expected to have a dipole moment. Hence the molecule is polar.
The answer is D but I gotta make this answer 20 characters real quick so ignore what I'm saying ja ja ja the cat go wow the I guess on this and I answer it a but the dog go wolf wolf moo
