D
The suns energy is radiating onto the earth, that is the only example
Answer:
P = 3.23 atm
Explanation:
Given data:
Number of moles of gas = 30 mol
Temperature = 120°C
Volume of gas = 300 L
Pressure of gas = ?
Solution:
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
120+273.15 = 393.15 K
P × 300 L = 30 mol × 0.0821 atm.L/mol.K × 393.15 K
P = 968.33 atm. L /300 L
P = 3.23 atm
Answer is valence electron, they all have total of 2 valence electron.
remember group number = valence electron
Answer:
When in direct contact, the fast-moving molecules in the radiator collide with the slow-moving molecules in the ice cube. Kinetic energy is transferred from the molecules in the radiator to the molecules in the ice cube, causing a slowdown of the radiator molecules and an acceleration of the ice molecules.
Explanation:
Carbohydrate; contains a low ratio of oxygen atoms.
