A combustion reaction occurs between one molecule of methane (CHa) and two molecules of oxygen (O2).
SCORPION-xisa [38]

The total number of atoms make up the products :

D) 1 carbon, 4 hydrogen, and 4 oxygen

<h3>Further explanation </h3>

Complete combustion of Hydrocarbons with Oxygen will produce CO₂ and H₂O compounds.

If O₂ is insufficient there will be incomplete combustion produced by CO and H and O

Hydrocarbon combustion reactions (especially alkanes)

For combustion of methane (CH₄) and two molecules of oxygen (O₂).

\tt CH_4+2O_2\rightarrow CO_2+2H_2O

The number of atoms make up the products

CO₂ : 1 carbon, 2 oxygen

2H₂O : 4 hydrogen , 2 oxygen

How do molecules of butene form polybutene?
Yuliya22 [10]

Answer:

Polybutene exists in two isomeric forms depending on where the carbon double bond is positioned in the monomer molecule. If it is between the first and second carbon atoms in a linear molecule, then the chemically accurate name of the resulting polymer is polybutene-1.

A particular forest is 10,000 acres. Determine its size in hectares. (1 hectare = 2.47
igor_vitrenko [27]

Taking into account the change of units, a particular forest is 4,048.58 hectares.

<h3>Definition of rule of three</h3>

The rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

If the relationship between the magnitudes is direct, the direct rule of three must be applied using the following formula, where a, b and c known data and x the variable to be calculated:

a ⇒ b

c ⇒ x

So: x= (c×b)÷ a

The direct rule of three is the rule applied in this case where there is a change of units.

<h3>Size in hectareas</h3>

To perform in this case the conversion of units, you must first know that 1 hectare = 2.47 acres.

So, the rule of three can be used as follow: if 2.47 acres is 1 hectare, 10,000 acres equals how many hectares?

2.47 acres ⇒ 1 hectare

10,000 acres ⇒ x

So: x= (10,000 acres ×1 hectare)÷ 2.47 acres

Solving:

<u><em>x= 4,048.58 hetares</em></u>

In summary, a particular forest is 4,048.58 hectares.

14.2 grams of Na2 so4 is dissolved in water to make a 2.50 L solution.What is molarity of solution?
FrozenT [24]

Answer:

The answer to your question is 0.04 M

Explanation:

Data

mass of Na₂SO₄ = 14.2 g

volume = 2.50 l

Molarity = ?

Process

1.- Calculate the molar mass of Na₂SO₄

Na₂SO₄ = (23 x 2) + (32 x 1) + (16 x 4) = 46 + 32 + 64 = 142 g

2.- Calculate the number of moles of Na₂SO₄

                    142 g of Na₂SO₄ ------------------- 1 mol

                     14.2 g of Na₂SO₄ ------------------  x

                                   x = (14.2 x 1) / 142

                                   x = 0.1 moles

3.- Calculate the molarity

Molarity = moles /volume

-Substitution

Molarity = 0.1 / 2.5

-Result

Molarity = 0.04
