Combustion! CH4, which is methane, reacts with oxygen to form carbon dioxide. (For future reference, if a compound is reacted with ONLY oxygen it is sure to be a combustion reaction)

Answer:

combustion reaction.  

Explanation:

Th given chemical equation is a combustion reaction.  

CH₄ or methane is a hydrocarbon. When a hydrocarbon reacts with oxygen it forms carbon dioxide and water.  

All other options are incorrect.

In a single replacement reaction one element replaces another element in a compound.  

Zn + H₂SO₄ = ZnSO₄ + H₂

In a double replacement reaction the cations of the reactants combines with a different anion of the reactant to form new products.

AgNO₃ + NaCl = AgCl + NaNO₃

In a decomposition reaction a complex molecule is broken down into simple molecules.  

H₂O₂ = 2H₂O + O₂

Answer:

The 3rd answer down.

Na²O (sodium oxide) will be a base when exposed to water H²O

Explanation:

Sodium Oxide Na²O, will become Sodium Hydroxide after being exposed to water (at 80% I believe).

The oxygen ion in Na²O has 2 extra electrons which makes it highly charged and very attractive to hydrogen ions. The attraction is so strong that when Na²O comes in contact with H²O, the O(-2) strips off a hydrogen from water, forming 2 x OH ions which of course are still strongly basic.

If 10.0 moles of O₂ are reacted with excess NO in the reaction below, and only 4.2 mol of NO₂ were collected, then what is the p
jonny [76]

Answer:

Percent yield = 21%

Explanation:

Find:

Percent yield

Computation:

1 mol O₂ produces 2 mol NO₂

So,

10 mol O₂ produces 20 mol NO₂

Percent yield = [Actual yield / Theoretical yield]100

Percent yield = [4.2 / 20]100

Percent yield = 21%
