Answer:
5.06atm
Explanation:
Using the combined gas law equation;
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
V1 = initial volume (Litres)
V2 = final volume (Litres)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the information provided in this question;
P1 = 1.34 atm
P2 = ?
V1 = 5.48 L
V2 = 1.32 L
T1 = 61 °C = 61 + 273 = 334K
T2 = 31 °C = 31 + 273 = 304K
Using P1V1/T1 = P2V2/T2
1.34 × 5.48/334 = P2 × 1.32/304
7.34/334 = 1.32P2/304
Cross multiply
334 × 1.32P2 = 304 × 7.34
440.88P2 = 2231.36
P2 = 2231.36/440.88
P2 = 5.06
The final pressure is 5.06atm
Step 1: Write the chemical formula.
Step 2: List all the atoms.
<span>Step 3: </span>Count<span> the number of </span>atoms<span> of each element in 1 molecule.
Step 4: Multiply the number of </span>atoms<span> of each by the coefficient.
Step 5: Make sure your answer makes sense.</span>
Answer is: <span>main products of the combustion of methane and other fossil fuels are carbon(IV) oxide and water.
</span>Balanced chemical
reaction of combustion of methane:
CH₄ + 2O₂ → CO₂ + 2H₂<span>O.
</span>In this combustion reaction, carbon is oxidized (from -4 to +4 oxidation number) and oxygen is reduced (from 0 to -2 oxidation number).
Kinetic energy is energy in motion. Which of these isn't in motion?
A lady walking slowly but surely down a street is moving, right? So that isn't right.
A hockey puck sliding on ice has motion.
A man running around a track definitely demonstrates kinetic energy.
But, a baseball glove doesn't. Maybe if it's moving on someone's hand, but by itself, it isn't moving.
