7 0

Answer:

Explanation:

To slow down this reaction, we can use any of the methods listed below:

  • Increase the size of the magnesium by using solid lumps of  the metal. This will take a much faster time to react than powered and granulated magnesium.
  • Reduce the concentration of the acid.
  • Let the reaction take place at a much lower temperature than that given.

These conditions will slow down a chemical reaction.

mote1985 [20]

Answer:

Propane

Explanation:

From the question given, we were told that 0.1240 kg of propane reacted with excess oxygen to produce 0.3110kg of carbon dioxide.

Since the reaction took place in the presence of excess oxygen, therefore, propane is the limiting reactant as all of it is used up in the presence of excess oxygen.

Nonamiya [84]
Answer is: formula of the complex is [Cr(NH₃)₂(SCN)₄<span>]</span>⁻<span>.
This complex has negative charge (-1) because chromium (central atom or metal) has oxidation number +3, first ligand ammonia has neutral charge and second ligand thiocyanate has negative oxidation number -1:
+3 + 2</span>·0 + 4·(-1) = -1.
