For the reaction represented by the equation 2H2 + O2 ® 2H2O, how many grams of water are produced from 6.00 mol of hydrogen?
Answers
The amount of water created by 6.00 mol of hydrogen is 108.12 grams.
To determine the number of grams of water produced from 6.00 mol of hydrogen, we need to use the stoichiometry of the balanced equation.
The balanced equation is:
2H₂ + O₂ → 2H₂O
From the balanced equation, we can see that for every 2 moles of hydrogen (H₂), 2 moles of water (H₂O) are produced. This means that the molar ratio of hydrogen to water is 2:2 or 1:1.
Given that we have 6.00 mol of hydrogen, we can conclude that an equal number of moles of water will be produced. Therefore, 6.00 mol of hydrogen will produce 6.00 mol of water.
To convert moles to grams, we need to use the molar mass of water, which is approximately 18.02 g/mol.
Hence, 6.00 mol of hydrogen will produce:
6.00 mol * 18.02 g/mol = 108.12 g of water.
Therefore, 6.00 mol of hydrogen will produce 108.12 grams of water.

a solution with an [OH-] concentration of 1.20 x 10-7M has a pOH and pH of?
Answers
Taking into account the definition of pH and pOH, the solution has a pOH of 6.92 and a pH of 7.08.
Definition of pHpH is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.
The pH is defined as the negative base 10 logarithm of the activity of hydrogen ions, that is, the concentration of hydrogen ions or H₃O⁺:
pH= - log [H⁺]= - log [H₃O⁺]
Definition of pOHSimilarly, pOH is a measure of hydroxyl ions in a solution and is expressed as the logarithm of the concentration of OH⁻ ions, with the sign changed:
pOH= - log [OH⁻]
Relationship between pH and pOHThe following relationship can be established between pH and pOH:
pOH + pH= 14
pOH and pH in this caseA solution has an [OH⁻] concentration of 1.20×10⁻⁷ M. Replacing in the definition of pOH:
pOH= - log (1.20×10⁻⁷ M)
Solving
pOH= 6.92
Then, pH is calculated as:
pH + 6.92= 14
pH= 14 - 6.92
pH= 7.08
Finally, the solution has a pOH of 6.92 and a pH of 7.08.

Kinda confused on this. i need some help.
Answers
To start, check to make sure it isn’t already balanced. If coefficients aren’t present, it’s assumed to be one. In this case, there’s just one aluminum on both sides, but the right hand side has one more fluorine than the left. This means that we’ll have to change the coefficients to make them match. Since we can’t multiply the two fluorines to make three with a whole number, we have to change this one and the one in front of the aluminum fluoride. Let’s put a 3 in front of F2 and a 2 in front of AlF3. So far, we have:
Al + 3F2 -> 2AlF3
Check the number of fluorines; sure enough, we have six on both sides. However, we’ve imbalanced the aluminums by balancing the fluorines. The fix is easy, though; change the coefficient from one to two in front of the aluminum to make them match. The result is therefore:
2Al + 3F2 -> 2AlF3
Check your element totals again; sure enough, they’re all balanced. This is the balanced chemical equation.

Answers
The temperature of a gas or liquid affects its density and therefore whether it rises or sinks.
The molecules of a substance with a higher temperature move faster and occupy more space. This means that warmer air or water is less dense than cooler air or water, and as a result, it will rise. This phenomenon is known as thermal buoyancy, and it is the reason why warm air rises and cool air sinks. This is due to the difference in the densities of the warm and cool air, which affects their relative positions in the atmosphere. Understanding the relationship between temperature and density is important in many areas of science and engineering, including meteorology, atmospheric science, and oceanography.

C. 5.0 x 10⁴ M
D. 50 x 10⁻⁴M
Answers
Answer:
A. 5.0 x 10⁻⁴M
Explanation:
Move the decimal point in 0.00050 M to the right, counting the steps required, until it is to the right of the first non-zero number, 5 in this case.
0.00050 M becomes 00005.0 M if we move the decimal point 4 spaces to the right. Moving to the right means taking a negative 1 step each time, The resulting count is -4, since we moved the decimal - 4 steps. This becomes the exponent for the 10: 10^-4. The 5.0 is attached to the 10^-4 to yield 5.0x10^-4 M, the answer.

A percent composition analysis yields
22. 6% phosphorus (P) and 77. 4%
chlorine (CI). What is the empirical
formula for the compound?
Answers
The empirical formula for the compound with 22.6% phosphorus (P) and 77.4% chlorine (CI) is PCl₃.
The empirical formula represents the simplest whole number ratio of atoms present in a compound. To determine the empirical formula, we need to convert the given percentages into moles.
Assuming we have 100 grams of the compound, we have 22.6 grams of phosphorus and 77.4 grams of chlorine. To convert grams to moles, we divide the mass by the molar mass of each element.
The molar mass of phosphorus (P) is approximately 31 grams/mol, and the molar mass of chlorine (CI) is approximately 35.5 grams/mol.
Converting the masses to moles, we find that we have approximately 0.73 moles of phosphorus and 2.18 moles of chlorine.
Next, we need to find the simplest whole number ratio of these moles. Dividing both moles by the smallest mole value (0.73 moles), we get a ratio of approximately 1:3.

Considering the stereochemistry of the inteediate I below, which of the products would you expect. Explain your answer.
Answers
The expected product is (R)-2-bromobutane.
Stereochemistry plays a crucial role in determining the outcome of chemical reactions. In the given question, the stereochemistry of the intermediate I needs to be considered to determine the expected product.
The intermediate I indicates a chiral carbon center, denoted by an asterisk (*), which means it has four different substituents attached to it. This chiral carbon results in two possible stereoisomers: (R)-2-bromobutane and (S)-2-bromobutane.
When a reaction occurs at a chiral carbon, the stereochemistry of the reactant is usually retained in the product, assuming no racemization or inversion takes place during the reaction. In this case, the intermediate I has an (R) configuration, which implies that the product will also have an (R) configuration.
Therefore, the expected product is (R)-2-bromobutane.

Answers
Copper has the highest conductivity of any metal used in electronics. The statement is false.
Silver is the element that conducts electricity the best, followed by copper and gold.
The earth's most conductive metal is by far silver. Silver only has one valence electron, which explains this. This one electron can also go about freely and encounter little opposition. As a result, some of the metals with this particular property are silver and copper.
Silver is the metal with the highest thermal and electrical conductivity because of its distinctive crystal structure and lone valence electron.
Since copper is the non-precious metal with the highest conductivity, it has a higher electrical current carrying capacity than other non-precious metals. The strength of the metal rises when tin, magnesium, chromium, iron, or zirconium are added to copper to create alloys, but its conductivity decreases.

in a reusable resource system, reducibility is independent of the order of reduction! true or false?
Answers
The statement "In a reusable resource system, reducibility is independent of the order of reduction" is true because, in such systems, the ability to reduce resources can be achieved without considering the specific order in which the resources are reduced.
Reusable resource systems are designed to enable efficient use of resources by reusing and recycling materials. Reducibility, in this context, refers to the ability to decrease the size, complexity, or quantity of resources used in a system without negatively affecting its performance or output.
When a reusable resource system is well-designed, the order of reduction should not impact the overall reducibility of the system. This is because the system should be able to adapt to various reduction sequences and still maintain its effectiveness.
In summary, it is true that in a reusable resource system, reducibility is independent of the order of reduction, allowing for more efficient and flexible resource management.

What is the ph of a 3.97x10^-2 m aqueous solution of hx if its ka is equal to 3.0x10^-3?
Answers
The pH of a 3.97x10^-2 m aqueous solution of hx if its ka is equal to 3.0x10^-3 is 1.96.
What is pH?pH is defined as the concentration of hydrogen ion in the solution.
Given,
Ka = 3.0x10^-3
As we know that,
Ka =( [H+] [X-])/[HX]
Let the concentration of [H+] = [X-] = x at any time t.
At the same time, concentration of [HX] = (0.0397-x)
Ka = x^2/(0.0397-x)
3.0x10^-3 = x^2/(0.0397-x)
x^2 = 0.1191 × 10^-3
x = 1.09×10^(-2)
x = 0.0109
The concentration of [H+] = 0.0109.
As we know that,
pH = -log[H+]
pH = -log(0.0109)
pH = -(-1.96)
pH = 1.96
Thus, we calculated that the value of pH of a 3.97x10^-2 m aqueous solution of hx if its ka is equal to 3.0x10^-3 is 1.96.
