Answer:
Geothermal power plants, which use heat from deep inside the Earth to generate steam to make electricity. Geothermal heat pumps, which tap into heat close to the Earth's surface to heat water or provide heat for buildings
Explanation:
Answer:
The molecules move more slowly and their average kinetic energy decreases
Explanation:
The increased temperature meant that the atoms in liquid had a greater average energy of motion so as the temperature decreases the reaction would be inverse.
The energy called Activation Energy (Ea) is required in all chemical cells during a chemical reaction. Sorry if I am wrong.
Answer: 11.2 L of at 273K and 202kPa
Explanation:
According to ideal gas equation:
P = pressure of gas = 202 kPa = 1.99 atm ( 1kPa= 0.0098 atm)
V = Volume of gas = 11.2 L
n = number of moles = ?
R = gas constant =
T =temperature =
According to avogadro's law, equal number of moles occupy equal volumes and contain equal number of molecules at same temperature and pressure conditions.
As 11.2 L of at 273K and 202kPa will have same moles as 11.2L of He (g) at 273K and 202kPa, thus they have same number of molecules.
How do you find volume at STP? It can be written as: V = nRT/P. “P” is pressure, “V” is volume, n is the number of moles of a gas, “R” is the molar gas constant and “T” is temperature. Record the molar gas constant “R”.
