216 grams of carbon 36 grams of hydrogen and 288 grams of oxygen whats the empirical formula
schepotkina [342]
Divide each wight by the  relative atomic mass

C = 216 / 12 =  18
H = 36 / 1 = 36
O = 288/16 = 18

Ratio of C:h:O = 1:2:1

Empirical formula is CH2O   Could be formaldehyde HCHO.

(45 pts) In which reaction is carbon reduced?
Sidana [21]

Answer:

Reductio is gain of electrons, while oxdation is loss. The oxidtion states of carbon in the reaction will show either of oxidation or reduction occurrence.

C_{2} H_{2}(g)  +H_{2} (g) → C_{2} H_{4}(g)

Explanation:

Electrons displacement is explained for each reaction below:

  1. +2 to +4 = loss of 2 more lectrons-------oxidation
  2. +4 throughout reaction----no exchange of electrons
  3. -4 to +4 =  loss of 4 electrons-----oxidation
  4. 0 to -2 = gain of 2 electrons-----reduction

Answer is:<span>increase [Cl</span>₂<span>] and remove HCl from the product.
</span>Chemical reaction: Cl₂ + CH₂Cl₂ → CHCl₃(chloroform) + HCl.
According to Le Chatelier's Principle, the position of equilibrium moves to counteract the change, the position of equilibrium will move so that the concentration of reactants decrease (Cl₂) and concentration of products of chemical reaction increase (CHCl₃) if increase concentration of reactants and decrease concentration of products.
