Answer:
0.082L or 82mL
Explanation:
Given parameters:
Pressure of gas = 780mmHg;
760mmHg = 1atm
780mmHg = 
= 1.03atm
Volume of gas = 80ml = 0.08L
Standard pressure = 1atm
Unknown:
Volume of gas = ?
Solution:
To solve this problem, we apply Boyle's law which states that "the volume of a fixed mass of gas is inversely proportional to the pressure if the temperature is constant".
Mathematically;
P₁ V₁ = P₂ V₂
P and V are temperature values
1 and 2 are initial and final states;
Insert the parameters and solve;
1.03 x 0.08 = 1 x V₂
V₂ = 0.082L or 82mL

Explanation:
Hola.
En este caso, debemos recordar que la fórmula semi desarrollada se relaciona con la fórmula estructural del compuesto orgánico a representar; de este modo, primeramente encontramos una cadena de cinco carbonos con un doble enlace en el primer carbono y dos radicales metil tanto en el segundo como en el tercer carbono. Por otro lado, la formula global muestra el tipo y número de átomos presentes en el compuesto, que para el dado, son siete átomos de carbono y catorce de oxígeno, según se puede observar en la imagen adjunta.
¡Saludos!
The three reasons that scientists found Rutherfor's nuclear atomic model to be fundamentally incomplete are as follows:
Number 1) according to Rutherford, the electrons revolve in completely
circular orbits. However, if this was true the charged electron would
simply fall into the nucleus after losing energy.
Number 2)
According to Rutherford's model, the nucleus itself only consisted of
protons. However, as we now know due to research in quantum mechanics,
if this was true this would make the atom unstable due to the cycle of
attraction and repulsion.
Number 3) The neutrons which have also
been discovered since to be an important part of the atom, are not
mentioned at all in Rutherford's model.
Answer:
B
Explanation:
ALL CELLS USE CELLULAR RESPIRATION
Explanation:
If two gases are present in a container, the total pressure int in the container is equal to the sum of the partial pressure of each individual gas. This is given by Dalton and it is known as Dalton's Law of Partial Pressure. The combined pressure of the two gases
