Glaciers cause erosion in two main ways: plucking and abrasion. Plucking is caused when sediments are picked up by a glacier. They freeze to the bottom of the glacier and are carried away by the flowing ice. ... The rocks and sediment grind away as the glacier moves
Answer: 873 kJ of energy will be required to break two moles of hydrogen gas.
Above chemical equation shows that two moles of hydrogen gas is reacting with one mole of oxygen gas to give two mole of water molecule.
Bond energy of H-H = 436kJ
According to reaction we have two moles hydrogen,so energy required to break the
H-H bond in two moles of hydrogen gas will be:
= 872kJ
872kJ of energy will be required to break H-H bond in two moles of hydrogen gas.
Answer:
An example of a single replacement reaction occurs when potassium (K) reacts with water (H2O). A colorless solid compound named potassium hydroxide (KOH) forms, and hydrogen gas (H2) is set free.
Explanation:
Answer:
1.39 atm
Explanation:
First find combined gas law equation. Then rearrange variable to match problem. You should get...
P2 = P1T2/T1
Next, change celcius temperatures to kelvin. Do this by adding 273 K (standard STP). Then fill in the numbers to go along with equation. You should get...
P2 = 1.22 atm x 455 K / 398 K = 1.39 atm
