2. What is the proper coefficient for balancing oxygen in the complete combustion of

butane shown in the equation below

2 CH10+? 02->8 C02 + 10 H2O

A. 13

B. 4

C. 5

D. 6.5

Answers

Answer:

A

Explanation:

8×2 + 10×1 = 26

so to balance it:

26÷2=13

For the given combustion reaction of butane gas, there are total 26 oxygens in the product side. Thus, the coefficient of O₂ must be 13 to equate both sides.

What is a balanced chemical equation?

The balanced chemical equation for a reaction represents the perfect stoichiometry of each reactants and products in the reaction. According to mass conservation law, the total mass in the product side must be equal to the total mass in the reactant side.

Therefore, each element must be equal in number on both side. The balanced equation for the combustion of butane is given below:

[tex]\rm 2 C_{4}H_{10} + 13 O_{2} \rightarrow 8 CO_{2} + 10 H_{2}O[/tex]

Now only the number of oxygen is balanced on both side. Hence, the proper coefficient for balancing oxygen in the complete combustion of butane gas is 13.

Question
How are chemical equations balanced?

Answers

Answer:

According to the law of conservation of mass, when a chemical reaction occurs, the mass of the products should be equal to the mass of the reactants. A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side

When asked why a chlorine atom gains one electron to form an anion with a 1- charge, a classmate answered, "Because noble gas configurations are stable." Is this statement generally true?

Answers

Noble gases have the maximum number of electrons in their outer shell. The statement made by the student about the stability of noble gases is generally true.

It is true that noble gases are stable elements. This can be attributed to the fact that they have the complete number of elements in their outer shell. That is why they hardly participate in any reactions.

The chlorine atom receives an electron from a donor element and attains a negative charge.

When two chlorine atoms bond covalently, they share electrons and thus attain the noble state configuration.

why does magnesium in an aqueous solution of magnesium chloride conduct electricity but solid magnesium chloride does not?

Answers

Answer:

Delocalized electrons

Explanation:

Magnesium Chloride is an ionic compound, so its lattice structure prevents the flow of electrons. However, when you convert the ionic compound into an aqueous solution it allows movement of electrons/ions due to the breakdown of the molecular forces which make it conductible. In short, Ionic compounds as a solid are not conductible but they are in an aqueous form.

A new element has been discovered. Scientists are trying to determine where it should it be placed on the periodic table. In order to do this they must determine the following about the element:

Answers

Elements are placed in order on the periodic table based on their atomic number, how many protons they have. In a neutral atom, the number of electrons will equal the number of protons, so we can easily determine electron number from atomic number.

draw a segment of polybutadiene containing three monomer units. connect each end of the segment with a bond to one of the r groups. the r groups represent the connecting carbon atoms in the monomers adjacent to the segment. be sure to draw all hydrogen atoms.

Answers

This problem states polybutadiene as a polymer from which we have to draw three monomeric units, showing the rest of it with a general notation (R).

In this case, we need to consider that the monomeric unit in polybutadiene is 1,3-butadiene:

[tex]CH_2=CH-CH=CH_2[/tex]

And takes the polymeric notation as:

[tex]-(CH_2=CH-CH=CH_2)_n-[/tex]

Thus, since we need three monomeric units, we bind them as shown on the attached picture, which shows the 1st, 2nd and 3rd ones. Moreover, note the two R's, which stand for the rest of the polymer as a general notation.

Some copper is palced in a previouly weighted crucible and reweighed .
Mass of crucible + copper = 5.92g
Mass of crucible = 4.65g
Clculate the mass of copper used in the experiment

Answers

Answer:  1.27g (mass of Copper)

Explanation:

We can find the mass of copper by finding the difference between the mass of the crucible and the copper, and just the crucible. This is possible since the mass that is left would be attributed to just the copper.

Mass of copper = (Mass of crucible + copper) - Mass of crucible

                          = 5.92 g - 4.65 g

                          = 1.27 g
