CH4+O2--->CO2+2H2O2
Write a few paragraphs predicting the products of the chemical reaction and explaining why you made this prediction. Your document should:
i. identify the products of the chemical reaction.
ii. explain why these are the products based on trends in the periodic table (the number of valence electrons, electronegativity, etc.).
iii. identify the types of bonds in the reactants and products.
iv. identify the number of each type of bond in the reactants and products.
v. identify the type of reaction.

Initial prediction : CH_4+O_2 transfers to CO_2+H_2O
Initial Explanation :
The products of this reaction are CO_2 and H_2O. These elements are Carbon Dioxide and Water. Atom's chemical properties are determined by the number of electrons in its outermost shells. Based on the number of electrons in the shells, it decides the reactivity of atoms. Atoms with the same number of electrons in the outer shells have similar chemical properties. If atoms have 1,2 or 3 valence electrons they react by giving out those electrons to become stable. If atoms have 6 or 7 electrons in the outer shell they react by taking in electrons to complete its outer shell.
So Methane has 8 valence electrons while Oxygen has 6. One molecule of methane combined with two oxygen molecules, react to form a carbon dioxide molecule, and two water molecules usually given off as steam or water vapor during the reaction and energy.
In the reaction, the bonds in the methane and oxygen come apart, the atoms rearrange and then re-bond to form water and carbon dioxide.The reactants are on the left side of the equation and the products are on the right. In the reaction, the bonds in the methane and oxygen come apart, the atoms rearrange and then re-bond to form water and carbon dioxide. No new atoms are created and no atoms are destroyed. This reaction is a combustion reaction.

Revised prediction : CH_4+O_2 transfers to CO_2+H_2O
Revised Explanation : I was correct initially so I put the same explanation.
The products of this reaction are CO_2 and H_2O. These elements are Carbon Dioxide and Water. Atom's chemical properties are determined by the number of electrons in its outermost shells. Based on the number of electrons in the shells, it decides the reactivity of atoms. Atoms with the same number of electrons in the outer shells have similar chemical properties.

In the reaction, the bonds in the methane and oxygen come apart, the atoms rearrange and then re-bond to form water and carbon dioxide. No new atoms are created and no atoms are destroyed. This reaction is a combustion reaction.
The reaction as shown is a combustion reaction.
The reaction; CH4 + O2 ---> CO2 + 2H2O2 is a combustion reaction because methane reacts with oxygen to yield carbon dioxide and water. Carbon is always tetravalent in its compounds hence there are four carbon oxygen bonds in the product. Lets recall that the bonds in CH4 re nonpolar because of the minimal electronegativity difference between carbon and hydrogen. Even though the bond in CO2 is polar but the eneitire molecule is nonpolar because the dipoles cancel out. Water is a polar molecule.
Hydrogen forms only one bond hence in water molecule, each hydrogen atom is bonded to a central oxygen atom. All the bonds in water and carbon dioxide as well as in methane and oxygen are covalent.

In the reaction given below, 23.5 grams of iron(III) oxide (Fe2O3) are reacted with excess carbon. What is the theoretical yield of iron metal?
2 Fe2O3 + 3 C --> 4 Fe + 3 CO2
If 14.5 grams of iron are recovered when the reaction is complete, what is the percent yield?
**Both answer should be written as XX.X
Answers
Answer:
Theoretical yield = 16.76 g
Percent yield = 87%
Explanation:
Given data:
Mass of iron oxide = 23.5 g
Theoretical yield of iron = ?
Actual yield of iron = 14.5 g
Percent yield of iron = ?
Solution:
Chemical equation:
2Fe₂O₃ + 3C → 4Fe + 3CO₂
Number of moles of iron oxide:
Number of moles = mass/molar mass
Number of moles = 23.5 g/ 159.69 g/mol
Number of moles = 0.15 mol
Now we will compare the mole of iron oxide with iron metal.
Fe₂O₃ : Fe
2 : 4
0.15 : 4/2×0.15 = 0.3
Mass of iron:
Mass = number of moles × molar mass
Mass = 0.3 mol × 55.85 g/mol
Mass = 16.76 g
Percent yield:
percent yield = (actual yield / theoretical yield)× 100
Percent yield = (14.5 g / 16.76 g) × 100
Percent yield = 0.87 × 100
Percent yield = 87%

10. The molar mass of CS2 is 76.14 g/mol. How many grams of CS2 are present in 10.00 mol?
Answers
Answer: C
Explanation:
There are 761.4 grams of CS2 in 10.00 mol.
To calculate the amount of grams present in a given amount of moles, the molar mass of the substance must be used, as follows:
[tex]m = MM \times mol[/tex]
In this way, just perform the following operation:
[tex]m = 76.14 \times 10[/tex]
[tex]m = 761.4 grams[/tex]
Thus, there are 761.4 grams of CS2 in 10 mol of the substance.

If the reacants of a chemical raction have 15 Carbon atoms, 72 Lead

Answers
Answer:
In the human body, potential energy is stored in the bonds between atoms and molecules. Chemical energy is the form of potential energy in which energy is stored in chemical bonds. When those bonds are formed, chemical energy is invested, and when they break, chemical energy is released. Notice that chemical energy, like all energy, is neither created nor destroyed; rather, it is converted from one form to another. When you eat an energy bar before heading out the door for a hike, the honey, nuts, and other foods the bar contains are broken down and rearranged by your body into molecules that your muscle cells convert to kinetic energy.

Which of the following is a difference between naming ionic and covalent compounds?
Group of answer choices
In ionic compounds the ending of the second element changes to -ide, but not in covalent compounds.
In covalent compounds, the prefix of the first element is always ignored but the prefix in the second element depends on the subscript of the element. In ionic compounds, the subscript on each element does not affect the name of the compound.
In covalent compounds the ending of the second element changes to -ide, but not in ionic compounds.
In covalent compounds, the prefix of the first element and second element depends on the subscript of each element. In ionic compounds, the subscript on each element does not affect the name of the compound.
Answers
The difference between naming ionic and covalent compounds is that, in ionic compounds the ending of the second element changes to -ide, but not in covalent compounds.
Ionic compounds are compounds that are formed by the by the transfer of electrons from a metal to a nonmetal. Covalent compounds are formed when electrons are shared between nonmetals.
For ionic compounds, the name of the second element(the nonmetal) often ends in -ide. For instance; sodium bromide, cesium oxide and potassium nitride. This does not apply when naming covalent compounds. The are named based on the subscripts of each element in the compound.

what happens to the temperatures when we have direct sunlight vs indirect sunlight?
Answers
Explanation:
When we have direct sunlight, the temperature is higher compared to indirect sunlight.
Direct sunlight is usually overhead whereas indirect sunlight is at an angle to the surface.
Direct sunlight impacts the surface with more energy concentrated on a smaller surface area. This warms the surface more. Indirect sunlight is diffuse and spreads over a wider area. This leads to a reduction in temperature.NEED HELP ASAP!!!!!!!Instructions

Explanation:
"According to Newton's third law of motion, when a hammer strikes and exerts force on a nail, the nail exerts a force of equal strength in the opposite direction on the first object."
Basically, if you push someone, they will fall over right?
Still, you will feel the force as you push them over, and you might stumble back while they are pinwheeling and falling into a pool.
That force is that torque when the person's weight is also pushing back at you while your force is pushing at them.

what process creates deltas?

A delta is a process that forms by river deposition into an ocean or marine environment.
Sediments carried by rivers in their old stage are brought near the mouth of an ocean. As the velocity of the river reduces, sediments begins to settle out. Small river tributaries breaks out into the ocean. Delta forms at an interphase between a small and large body of water. The deposited sediments forms distinct shapes as they enter the larger body of water.How many molecules/atoms of excess reactant will remain after the reaction is complete?
