PLS ANSWER FAST AHAH<br><br> distilled water is a pure substance <br> true or false ?
mr Goodwill [35]

Answer:

True

Explanation:

If you see distilled water, it's a pure substance. That means that there are only water molecules in the liquid. A mixture would be a glass of water with other things dissolved inside, like one of those powders you take if you get sick or Kool-Aid.

<h3>your query : </h3>

Which statement about photosynthesis is FALSE?

Answer:

b. Oxygen is needed as a reactant to produce

glucose is the incorrect statement here

Explanation:

plants uses simple raw materials to prepare their food , which includes water ( H2O ) and Carbon dioxide ( CO2 ).

and traps sunlight by Green pigments known as chlorophyll and stores these energy in bonds of glucose molecules

so ,

after this reaction glucose and oxygen is formed as products

● hence we conclude that Oxygen is not needed as a reactant to produce glucose , oxygen is the bi product formed during photosynthesis.

How would you describe the strength of the bonds that result from resonance in SO3?
Sladkaya [172]

Answer:

All bonds are equivalent in length and strength within the molecule.

Gaseous SO3 is a trigonal planar molecule that exhibit a D3h symmetry group.

Sulfur has sp2 hybridization and it has 6 outer electrons which make the bonds with the oxygen.

Its constituent sulfur atom has an oxidation state of +6 and a formal charge of 0.

The Lewis structure is made up of one S=O double bond and two S–O dative bonds that doesn't not engage the d-orbitals. ( Thus, SO3 molecule has three double bonded oxygen to the central sulfur atom). This explains the strength.

It gaseous form had a zero electrical dipole moment  because of the 120° angle between the S-O bonds.
