A sample of h gas (2.0 l) at 3.5 atm was combined with 1.5 l of n gas at 2.6 atm pressure at a constant temperature of 25c into

nadya68 [22]

For this problem, assume ideal gas then we use the Combined Gas Law.

P₁V₁/T₁ + P₂V₂/T₂ = PV/T
where P, V and T are the total pressure, volume and temperature

Since temperature is kept constant, the equation is simplified to:

P₁V₁ + P₂V₂ = PV
(3.5 atm)(2L) + (2.6 atm)(1.5 L) = (P)(7 L)
Solving for P,
P = 1.56 atm

You can use mole ratios and molar mass to determine the masses of substances involved in a chemical reaction. Using the periodic

Neporo4naja [7]

Answer : Molar mass of the $Fe_2O_3$ is 159.7 g/mol.

Molar mass of the $Al_2O_3$ is 101.96 g/mol.

Explanation:

Molar mass of $Fe_2O_3$ :

$\text{Atomic mass of Fe}\times 2+\text{Atomic mass of O}\times 3$

Molar mass = $55.85 g/mol\times 2+16.00 g/mol\times 3=159.7 g/mol$

Molar mass of the $Fe_2O_3$ is 159.7 g/mol

Molar mass of $Al_2O_3$ :

$\text{Atomic mass of Al}\times 2+\text{Atomic mass of O}\times 3$

Molar mass = $26.98 g/mol\times 2+16.00 g/mol\times 3=101.96 g/mol$

Molar mass of the $Al_2O_3$ is 101.96 g/mol

Answer : La carga nuclear efectiva (Zef) es la carga positiva neta experimentada por un electrón en un átomo polielectrónico. El término "efectiva" se usa porque el efecto pantalla de los electrones más cercanos al núcleo evita que los electrones en orbitales superiores experimenten la carga nuclear completa
