Answer:
true because the bonds cannot be broken down
Answer i think u meant to write PCl3 instead of BCl3
:Taking the example of BCl3 and NH3, you have non-polar BCl3 (because of its flat geometry and symmetrical distribution of electrons) forming a polar non-covalent bond with the NH3 molecule (polar because of its tetrahedral geometry with a lone-pair of electrons attached to the nitrogen).
Polar molecules are SO2, CH2Cl2 and PCl3 are Polar molecules.
Explanation:
Water (H2O) is a polar molecule. ...
Ethanol is polar because the oxygen atoms attract electrons because of their higher electronegativity than other atoms in the molecule.
Ammonia (NH3) is polar.
Sulfur dioxide (SO2) is polar.
Hydrogen sulfide (H2S) is polar.

Smaller the atomic size get smaller as it goes across a period. This is because periods all have the same amount of valence electron shell numbers (like period 2 has 2 valance shells around the atom) but at the same exact time, the number of protons increase going down the period. This means there’s more/a stronger pull from the protons to the outer balance electrons making the valance electron layers pull inward more, but on the next layer of new balance electron shell is formed so the distance between the outer most balanced electron in the protons is wider than the previous level, but like before the gap decreases as a you go down the period. Hope this makes sense
Answer:
Zn(s) produces H₂ when is added to a strong acid solution
Explanation:
Look at this example:
2Zn (s) + 2HCl (aq) → 2ZnCl (aq) + H₂ (g)
It is a redox reaction, where the zinc is oxidized and the H, reducted.
Zn → Zn⁺ + 1e⁻
2H⁺ + 1e⁻ → H₂
The statement that is true about physical change is that it changes it’s substance but it keeps the same properties? I think so
