In a laboratory 178.8 g of water is separated into hydrogen gas and oxygen gas. the hydrogen gas has a mass of 20.0 g what is the mass of the oxygen gas produced?

Answers

Answer 1
Answer: Below is the solution:
n equation showing conservation of mass of reactants and products: 
2H2O --> 2H2 & O2 

what is the mass of the oxygen gas produced, from 178.8 g H2O , (using molar masses: 
178.8 g H2O @ (1mol O2)(@ 32.00 g/mol) / (2molH2O)(18.02g/mol) = 
your answer (4 sigfigs): 158.8 g O2 

178.8 g H2O ---> 20.0 H2 & 158.8 O2
Answer 2
Answer:

To find the mass of the oxygen gas produced, we can subtract the mass of the hydrogen gas from the total mass of water. Therefore, the mass of the oxygen gas produced is 158.8 grams.

Given:

Mass of water = 178.8 g

Mass of hydrogen gas = 20.0 g

To calculate the mass of oxygen gas:

Mass of oxygen gas = Mass of water - Mass of hydrogen gas

Mass of oxygen gas = 178.8 g - 20.0 g

Mass of oxygen gas = 158.8 g

What causes the most land erosion in the United States today?

Answers

Answer:

Explanation:

1. Agriculture: Extensive agricultural practices, such as improper land management, overgrazing, and the use of heavy machinery, can lead to soil erosion. When soil is exposed and not adequately protected by vegetation, it becomes vulnerable to wind and water erosion.

2. Construction and Urbanization: The construction of roads, buildings, and other infrastructure often involves the removal of vegetation and the disturbance of natural landscapes. This can increase the likelihood of erosion, especially during rainfall events, as the natural drainage patterns and soil stability are disrupted.

3. Deforestation: The removal of forests for timber, agriculture, or urban development exposes the soil to erosion. Forests play a crucial role in preventing erosion by holding the soil together with their roots and providing a protective layer of vegetation.

4. Mining Activities: Mining operations can result in significant land disturbance, leading to erosion. Excavation and removal of soil or rock can destabilize slopes and expose bare surfaces prone to erosion.

5. Improper Land Management Practices: Improper land management practices, such as improper irrigation, inadequate soil conservation techniques, and over-extraction of resources, can exacerbate erosion. These practices can deplete the soil's fertility and disrupt its natural balance, making it more susceptible to erosion.
