53 yards per houris a speed value and when converted gives 320544 inches per week.
The speed value is defined by the distance traveled by the object with reference to the time. It is a scalar quantity, with a magnitude but no direction. The speed is calculated using the formula:
Speed = Distance ÷ Time
It can be measured in, meters per second, miles per hour, kilometers per hour, etc.
From the known data:
7 days per week
24 Hours per day
3 ft per yard
12 inches per feet
The conversion of yards per hour into inches per week is given as:
= 53 yards per hour × 3 feet per yard × 12 inches per foot × 24 hour per day × 7 day per week
= 53 × 3 × 12 × 24 × 7
= 320,544 inches per week
Therefore, the unit is converted and is 320,544 inches per week.

Answer: a) Balancing chemical equations
Explanation:
We are given that this student is struggling to have the "equations balanced to cancel out." This means that answer option A gives the specific problem they are facing, a) Balancing chemical equations. While they may be struggling to cancel things out, they say "I can't seem to have the equations balanced." This leads us to the specific answer.
The application of Hess's law involves balancing reactions and using stoichiometry to add or subtract equations, thus obtaining a desired reaction. The law states that the enthalpy change for a total process is the sum of enthalpy changes for individual steps. One can think of complex reactions as occurring in individual steps, helping to balance or cancel out equations.
In your question, you're grappling with the utilization of Hess's law and balancing or canceling out equations. To solve such problems with Hess's law, it's crucial first to understand what this law implies. Hess's law states that if a chemical process can be written as the sum of multiple steps, the enthalpy change of the total process equals the sum of the enthalpy changes for individual steps. This law works because enthalpy is a state function, which means that enthalpy changes depend mainly on the initial and final state, not the path through which the process passed.
For example, take the reaction of carbon with oxygen to form carbon dioxide. You can write this reaction as a direct process: C(s) + O₂(g) = CO₂(g). But you can also divide it into two steps: 1. Carbon and oxygen form carbon monoxide (C(s) + 02 (8) -> CO(g)), and 2. Carbon monoxide reacts with oxygen to form carbon dioxide (CO(g) + 1-0₂ (8) -> CO₂(g)). The reaction, when written as a sum of these steps, will give you the overall reaction, helping to balance or cancel out the equations.
The challenging aspect of Hess's law is the manipulation of equations to achieve cancellation and balance. Remember, stoichiometry rules allow us to change the quantities of reactants and products (but not their identity) when we have balanced equations. It's akin to mathematical equations, where one can multiply an entire equation by a constant to obtain an equivalent equation.

Answer:
3.00 moles
Explanation:
To calculate the number of moles of sulfur dioxide (SO2) in 192 grams of the gas, you can use the molar mass of SO2. Sulfur dioxide has a molar mass of approximately 64.0638 grams per mole.
Now, you can use the formula:
Number of moles = Mass (g) / Molar mass (g/mol)
Number of moles = 192 g / 64.0638 g/mol ≈ 2.997 moles
So, there are approximately 3.00 moles of sulfur dioxide in 192 grams of the gas.
The answer would be furnace.
Answer:
the correct answer is furnace
b) higher as the satellite moves away
c) lower as the satellite approaches
