Explanation:
The detailed solution is shown on the image. From the detailed chemical reaction, we calculate the mass of methane required in the standard combustion reaction of methane and use it to estimate the mass required to produce the quantity of heat required in the question.
Final answer:
To supply the energy needed for an average home in Colorado, approximately 3.58 x 10^8 grams of natural gas (methane) must be burned.
Explanation:
To calculate the amount of natural gas (methane) required to supply the energy needed for an average home in Colorado, we can use the balanced chemical equation for the combustion of methane:
CH4(g) + 2O2(g) → CO2(g) + 2H2O(l)
The molar enthalpy change for this reaction (ΔH°rxn) is -890.4 kJ/mol. First, we need to convert the energy requirement from kilojoules to joules:
2.00 x 107 kJ = 2.00 x 1010 J
Next, we can use the molar enthalpy change to calculate the number of moles of methane required:
moles of CH4 = energy requirement / mlar enthalpy change
moles of CH4 = 2.00 x 1010 J / (-890.4 kJ/mol)
Finally, we can convert the number of moles of methane to grams using the molar mass of methane:
molar mass of CH4 = 12.01 g/mol + 4(1.008 g/mol) = 16.04 g/mol
grams of CH4 = moles of CH4 * molar mass of CH4
Therefore, the number of grams of natural gas (methane) that must be burned to supply this energy is approximately:
grams of CH4 = (2.00 x 1010 J / (-890.4 kJ/mol)) * 16.04 g/mol
Simplifying the calculation:
grams of CH4 ≈ 3.58 x 108 g

Answer:
-1
Explanation:
The sum of the oxidation states of all the atoms in a neutral compound is zero. Then the following equation must be satisfied:
number of atoms of C * oxidation state of C + number of atoms of H * oxidation state of H + number of atoms of O * oxidation state of O = 0
Replacing with data and calling the unknown x, we get:
2*x + 4*1 + 1*(-2) = 0
2*x + 2 = 0
x = (-2)/2
x = -1

When making a guess, you are forming a hypothesis.
A hypothesis is a statement you make based on your observations of a certain phenomenon, so it's an educated guess.
You will then carry out an experiment whose results will hopefully support your hypothesis.
Explanation:
Hypothesis is a supposition or projected clarification created on the premise of restricted proof as a place to begin for more investigation.A hypothesis may be a tentative, testable answer to a scientific question. Once a person encompasses a scientific question she is fascinated by, the person reads up to search out out what's already far-famed on the subject. Then she uses that data to make a tentative answer to her scientific question. Typically folks discuss with the tentative answer as "an educated guess."

A: the Oxygen has a partial negative charge which attracts atoms and molecules that have a position or partial positive charge
B: The Hydrogen has a partial negative charge which attracts atoms and molecules that have a positive or partial positive charge
C: Because Oxygen is extremely electronegative it attracts atoms and molecules with a negative or partial negative charge
D: Because Hydrogen has a very low electronegative rating it attracts atoms and molecules with a positive or partial positive charge

Considering the definition of hydrogen bond, the correct answer is option A: he Oxygen has a partial negative charge which attracts atoms and molecules that have a position or partial positive charge.
In hydrogen bonds, a molecule that presents hydrogen interacts with another that presents an atom with high electronegativity, such as oxygen, fluorine or nitrogen (O, F, N). In this way, between the hydrogen, which has a low electronegativity and the electronegative atom, an interaction is established, due to their opposite charges.
On the other hand, electronegativity is the ability of an atom to attract shared electrons in a covalent bond.
In the case of water, because oxygen is more electronegative than hydrogen, electrons, which have a negative charge, are more likely to be closer to the oxygen atom than to the hydrogen atom, which causes each hydrogen atom to have a positive charge is called a positive partial charge, and that of oxygen, a negative charge, since it has the electrons closer together.
In summary, the correct answer is option A: he Oxygen has a partial negative charge which attracts atoms and molecules that have a position or partial positive charge.

Answer:
Opposite charges attract one another. The slight positive charges on the hydrogen atoms in a water molecule attract the slight negative charges on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond.
