Answer:
Work done = 2307.17 j
Explanation:
Given data:
Work done = ?
Initial volume =18.38 L
Final volume = 7.11 L
Pressure = 2.02 atm
Solution:
work done = W = -PΔV
ΔV = V₂- V₁
work done = w = -P(V₂- V₁)
Now we will put the values in formula.
W = - 2.02 atm (7.11 L - 18.38 L)
W = - 2.02 atm (-11.27 L)
W = 22.77 atm.L
atm.L to joule:
22.77 atm.L × 101.325 J / 1L.atm
2307.17 j
Answer:
808
Step-by-step explanation:
One serving of Original Pringles = 28 g = 150 Cal
Pringles ⟶ Cal 50 g × (150 Cal/28 g) = 268 Cal
Cal ⟶ J 268 Cal × (4184 J/1 Cal) = 1.121 × 10⁶ J
J ⟶ N·m 1.121 × 10⁶ J × (1 N·m/1 J) = 1.121 × 10⁶ N·m
N·m ⟶ m 1.126 × 10⁶ N·m/455N = 2460 m
m ⟶ km 2460 m × (1 km/1000 m) = 2.46 km
km ⟶ mi 2.46 km × (0.6214 mi/1 km) = 1.53 mi
mi ⟶ ft 1.53 mi ×(5280 ft/1 mi) = 8080 ft
ft ⟶ flights 8080 ft × (1 flight/10 ft) = 808 flights
The student would have to climb 808 flights of stairs to burn off the energy from 50 g of Pringles [that's equivalent to climbing the stairs in the Salesforce Tower (1070 ft) in San Francisco about 7½ times].
Answer:
The trees' growth might be affected
Explanation:
A pH above 7 indicates that the soil is no more acidic and that it had turned basic or alkaline in nature. This may affect the functioning of enzymes as this value is very far from optimum pH value. Thus growth is affected.
only reactants are present
If equllibrium constant is greater than 10^3 then product
predominates
If equllibrium constant is greater than 10^ -3 then reactant predominates
in between 10^3 and 10^-3 the reaction is in equllibrium
and we see that the above value is 10^-31, it is very small so the answer is reactants are presents
Parrallax is used to calculate the distance.
