<span> la gravedad en la tierra no es constante ni mucho menos porque depende de la distancia al centro de la tierra... y la tierra no es perfectamente esferica </span>
<span>respecto a la pregunta, la presion atmosferica viene siendo proporcional al peso que el aire ejerce sobre nosotros. Mientras mas gravedad hay en un planeta, mayor es la presion atmosferica a cierta altura. </span>
<span>Ahora, en un mismo planeta, la aceleracion de gravedad disminuye con la altura (porque se esta mas lejos del centro) y la presion tambien disminuye con la altura, porque hay menos aire sobre nuestras cabezas. </span>
<span>espero q te sirva.</span>
Answer:
3.762 atm.
Explanation:
- We can use the general law of ideal gas: PV = nRT.
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and T are constant, and have different values of P and V:
<em>(P₁V₁) = (P₂V₂)</em>
<em></em>
P₁ = 894.0 torr, V₁ = 534.0 mL,
P₂ = ??? torr, V₂ = 167.0 mL.
- Applying in the above equation
(P₁V₁) = (P₂V₂)
<em>∴ P₂ = (P₁V₁)/V₂</em> = (894.0 torr)(534.0 mL)/(167.0 mL) = <em>2859 torr.</em>
- To convert from torr to atm:
1.0 atm = 760.0 torr.
<em>∴ P₂ </em>= (2859 torr)(1.0 atm/760 torr) = <em>3.762 atm.</em>
Answer:
Explanation:
The chemical formula for methane is 
The chemical formula for oxygen is 
The chemical formula for carbon dioxide is 
The chemical formula for water is 
Methane burns in oxygen to give carbon dioxide and water:
The balanced equation that will ensure an equal number of each atom on the left and right-hand sides of the equation would be:
The answer is 9. Calcium nitrate is made up
of 3 different elements that equal 9 atoms.
Answer:
He.
Explanation:
- Graham's law states that the effusion rate is inversely proportional to the molecular weight. It means that the gas with the lowest molecular weight will have the highest effusion rate.
The molecular weights of the given gases are:
Cl₂ = 70.9 g/mol.
He = 2.0 g/mol.
O₂ = 32.0 g/mol.
Ne = 20.17 g/mol.
<em>Since He has the smallest molecular mass, so it will have the highest rate of effusion.</em>
