The average speed is 0.28
Answer:
the maximum safe operating temperature the engineer should recommend for this reaction is 616 °C
Explanation:
Given the data in the question;
First we calculate the Volume of the steel cylinder;
V = πr²h
radius r = Diameter / 2 = 27 cm / 2 = 13.5 cm
height h = 32.4 cm
so we substitute
V = π × ( 13.5 cm )² × 32.4 cm
V = π × 182.25 cm × 32.4 cm
V = 18550.79 cm³
V = 18.551 L
given that; maximum safe pressure P = 3.10 MPa = 30.5946 atm
vessel contains 0.218kg or 218 gram of carbon monoxide gas
molar mass of carbon monoxide gas is 28.010 g/mol
so
moles of carbon monoxide gas n = 218 gram / 28.010 g/mol = 7.7829 mol
we know that;
PV = nRT
solve for T
T = PV / nR
we know that gas constant R = 0.0820574 L•atm•mol⁻¹ K⁻¹
so we substitute
T = ( 30.5946 × 18.551 ) / ( 7.7829 × 0.082 )
T = 567.5604 / 0.6381978
T = 889.317387 K
T = ( 889.317387 - 273.15 ) °C
T = 616.167 ≈ 616 °C { 3 significant digits }
Therefore, the maximum safe operating temperature the engineer should recommend for this reaction is 616 °C

Explanation:
A. The patch's area in square kilometers (km²) is 1.61×10⁻⁹ km²
B. The cost of the patch to the nearest cent is 734 cents
<h3>A. How to convert 16.1 cm² to square kilometers (km²)</h3>
We can convert 16.1 cm² to km² as illustrated below:
Conversion scale
1 cm² = 1×10⁻¹⁰ km²
Therefore,
16.1 cm² = 16.1 × 1×10⁻¹⁰
16.1 cm² = 1.61×10⁻⁹ km²
Thus, 16.1 cm² is equivalent to 1.61×10⁻⁹ km²
<h3>B. How to determine the cost in cent</h3>
We'll begin by converting 16.1 cm² to in². This can be obtained as illustrated below:
1 cm² = 0.155 in²
Therefore,
16.1 cm² = 16.1 × 0.155
16.1 cm² = 2.4955 in²
Finally, we shall the determine the cost in centas fo r llow:
- Cost per in² = $2.94 = 294 cent
- Cost of 2.4955 in² =?
1 in² = 294 cent
Therefore,
2.4955 in² = 2.4955 × 294
2.4955 in² = 734 cents
Thus, the cost of the patch is 734 cents

Answer:
2.9 g
Explanation:
There is some info missing. I think this is the original question.
<em>Ammonium perchlorate is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen gas, chlorine gas, oxygen gas, water, and a great deal of energy.
</em>
<em>What mass of water is produced by the reaction of </em><em>9.6 g</em><em> of ammonium perchlorate?</em>
<em />
Step 1: Given data
Mass of ammonium perchlorate: 9.6 g
Step 2: Write the balanced equation
2 NH₄ClO₄(s) → N₂(g) + Cl₂(g) + 2 O₂(g) + 4 H₂O(l)
Step 3: Calculate the moles corresponding to 9.6 g of ammonium perchlorate
The molar mass of ammonium perchlorate is 117.49 g/mol.

Step 4: Calculate the moles of water formed from 0.082 moles of ammonium perchlorate
The molar ratio of NH₄ClO₄ to H₂O is 2:4. The moles of water formed are 4/2 × 0.082 mol = 0.16 mol
Step 5: Calculate the mass corresponding to 0.16 moles of water
The molar mass of water is 18.02 g/mol.
