The key  characteristic  of oxidation-  reduction   reaction  is electrons   are  exchanged  ( answer  C)

   <u><em>Explanation</em></u>

  • Oxidation-reduction   reaction  is type  of reaction  that involve a transfer  of electrons  between two  species.

Example  of oxidation - reduction  reaction is

  CH4  +2O2 →   CO2  + 2H2O

  from reaction above C  atom  is oxidized  from  oxidation state -4  to 4.

   On the  other hand O atoms   are reduced  from oxidation state of 0 to  2-.  therefore   there is exchange  of electrons  between  C atoms  and O atoms.

If 26.2 grams of a pure compound contain 8.77 × 1022 molecules, what is the molecular weight of this compound? Answer in units o
Nataly [62]

Answer:

Mw = 179.845 g/mol

Explanation:

  • Mw [=] g/mol

∴ w = 26.2 g

∴ 1 mol = 6.02 E23 molecules.......Avogadro's number

⇒N° moles = 8.77 E22 molecules * ( mol / 6.02 E23 molecules ) = 0.146 mol

⇒ Mw = 26.2 g / 0.146 mol = 179.845 g/mol

If a plant produces 8.46 mol C6H12O6, how many moles of H2O are needed?
Ierofanga [76]

Answer:

50.76 mol H2O.

Explanation:

The photosynthesis follows the equation:

6CO2 + 6H2O ---> C6H12O6 + 6O2

This means that 6 mol of H2O are needed to obtain 1 mol of C6H12O6 (see the numbers that precedes every molecule to know how many mols are in game).

So we can say that:

1 mol C6H12O6 --------- 6 mol H2O

8.46 mol C6H12O6 -----x= 8.46 x 6 : 1 = 50.76 mol H20
