Answer:
2.52atm for sure
Explanation:
We know that:
P1= 2.80atm
T1= 400k
T2= 360k
And we want to find P2= ?
We have an equation: P1/T1 = P2/T2
Multiple both side by T2 to remove it
P2 = 2.52
In chemistry Electronic configuration, also called electronic structure, the arrangement of electrons in energy levels around an atomic nucleus. According to the older shell atomic model, electrons occupy several levels from the first shell nearest the nucleus, K, through the seventh shell, Q, farthest from the nucleus.

Answer:
20.10 pounds of carbon dioxide are produced from burning one gallon of gasoline.
Explanation:
Volume of the gasoline = V = 1 gal = 3785.41 mL
Density of the gasoline = d = 0.78 g/ml
Mass of gasoline = m = ?
Moles of gasoline = 
According to reaction, 2 moles of octane gives 16 moles of carbon dioxide gas.
Then 25.90 moles of octane will give:
Mass of 207.20 moles of carbon dioxide gas:
= 207.20 mol × 44 g/mol = 9,116.86 g
1 pound = 453.592 grams
20.10 pounds of carbon dioxide are produced from burning one gallon of gasoline.
Answer:
groundwater
Explanation:
US and Canadian researchers recently calculated the total amount of the world's groundwater and estimated that it is equivalent to a lake 180 metres deep covering the entire Earth. This makes groundwater the largest active freshwater resource on the planet.
It had a more immediate effect because it enters directly into the blood stream.
