The sun heats up the air at different rates. Weather is caused by uneven heating
Answer:
It is equal to the number of moles of acid that reacted. When Oxalic acid is your limiting reactant it is the # of moles of oxalic acid used. When NaOH is your limiting reactant it is equal to the number of moles of NaOH used.
Answer:
732.0601 mmHg
Explanation:
Given data:
Pressure = 97.6 KPa
Given pressure in mmHg = ?
Solution:
Kilo pascal and millimeter mercury both are units of pressure.
Kilo pascal is denoted as "KPa"
Millimeter mercury is denoted as " mmHg"
Kilo pascal is measure of force per unit area while also define as newton per meter square.
It is manometric unit of pressure. It is the pressure generated by column of mercury one millimeter high.
Conversation of kilopascal to mmHg:
97.6 × 7.501 = 732.0601 mmHg
Answer:
Bohr's model of the hydrogen atom is based on three postulates:
1) An electron moves around the nucleus in a circular orbit,
2) An electron's angular momentum in the orbit is quantised,
3) The change in an electron's energy as it makes a quantum jump from one orbit to another is always accompanied by the emission or absorption of a photon. Bohr's model is semi-classical because it combines the classical concept of electron orbit (postulate 1) with the new concept of quantisation ( postulates 2 and ).
First, we convert the depth of the water into meters. This is:
60 feet = 18.3 meters
Now, we compute the additional pressure exerted due to the water, which is given by:
Pressure = density * gravitational field strength * height
P = 1000 * 9.81 * 18.3
P = 179.5 kPa
The atmosphere pressure is 101.325 kPa
The pressure of the gas bubbles 60 feet under water will be:
179.5 + 101.325 = 280.825 kPa
The pressure at the surface of the water will be equal to the atmospheric pressure, 101.325 kPa.
Because of this decrease in external pressure as gas bubbles rise, they are seen to expand.
