charle [14.2K]
Answer:
Reactants: Ethanol (C₅H₅OH), Oxygen (O₂)

Products: Carbon dioxide (CO₂) and Water (H₂O)

Explanation:
Let’s rewrite each part of the described situation in chemical equation terms.

Ethanol - C₂H₅OH
is burned in the prescence of - +
oxygen - O₂
producing - →
carbon dioxide - CO₂
and - +
water - H₂O

Chemical equation:
C₂H₅OH + O₂ → CO₂ + H₂O

The terms on the left side of a chemical equation are reactants, and the terms on the right side of a chemical equation are products.

Therefore, since we know this, ethanol (C₂H₅OH) & oxygen (O₂) are the reactants, and carbon dioxide (CO₂) & water (H₂O) are the products.

__ SnCl4 → __ Sn + __ Cl2
Kisachek [45]

Answer:

Sn (s) + 2 Cl2 (g) → SnCl4 (l)

This is an oxidation-reduction (redox) reaction:

4 Cl0 + 4 e- → 4 Cl-I

(reduction)

Sn0 - 4 e- → SnIV

(oxidation)

Cl2 is an oxidizing agent, Sn is a reducing agent.

If the molar mass of NaCl is 58.44 g/mol, what amount of NaCl (in mol) is contained in 250.0 mg of NaCl?
4vir4ik [10]

Answer: 0.004 moles

Explanation:

Amount of substance= mass/ molar mass

Mass= 250mg or 0.25g

Molar mass= 58.44gmol-1

Amount= 0.25/58.44

= 0.004 moles
