The pressure of the oxygen gas collected : 718 mmHg
<h3>Further explanation</h3>
Given
P tot = 748 mmHg
P water vapour = 30 mmHg
Required
P Oxygen
Solution
Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases
Can be formulated:
P tot = P1 + P2 + P3 ....
The partial pressure is the pressure of each gas in a mixture
P tot = P H₂O + P Oxygen
P Oxygen = 748 mmHg - 30 mmHg
P Oxygen = 718 mmHg
Answer:
in position and time graphs the slope of line indicates the velocity
Answer
Establishing laws
Explanations
The steps involved when performing a scientific research are;
• Making observations
• Forming a question after making an interesting observation, a scientist should find more about the concept identified.
• Forming a hypothesis
• Conducting the experiment
• Analyzing the data
• Drawing a conclusion
The amount of CO2 in the atmosphere is increasing is true about the carbon cycle.I know why the option a wont work,because, on the off chance that they didnt spin around the sun, then they would simply be drifting around in straight lines colliding with each other.
Answer:
Explanation:
Kinetic energy is the energy possessed by an object due to its motion. If an object is moving, then it has kinetic energy. If an object has kinetic energy, then it is moving. Many students confuse kinetic energy with potential energy.
