Answer:
SF2 and SF4 only are polar.
Explanation:
With respect to the SF2 molecule, this molecule is not symmetrical, it has a negative and a positive side, which makes it a polar molecule, due to the differences in electronegativity.
In the SF4 molecule the four bond dipole moments are equal and due to the molecular geometry they do not cancel each other resulting in a polar molecule.
SF6 is a nonpolar molecule because the six fluorine atoms are symmetrically arranged around the sulfur atom, the bonding dipoles cancel each other.
Answer:
Explanation:
<u>Given the following data;</u>
Number of loops in primary coil, Np = 1 loop.
Number of loops in secondary coil, Ns = 8 loops
Voltage in secondary coil, Vs = 120V
To find the voltage in the primary coil, Vp;
Transformer ratio is given by the formula;
Making Vp the subject of formula;
Substituting into the equation, we have;
Therefore, the voltage in the primary coil, Vp is 15 Volts.
Answer:
34.02 g.
Explanation:
Hello!
In this case, since the gas behaves ideally, we can use the following equation to compute the moles at the specified conditions:
Now, since the molar mass of a compound is computed by dividing the mass over mass, we obtain the following molar mass:
So probably, the gas may be H₂S.
Best regards!
