When is the principle of conservation of mass true?
B. Only for reactions that take place in closed systems.
Hope this answers your question!
Answer:
The moles of solute
Explanation:
When you make a dilution, moles of solute does not change when you add solvent.
In concentrated solution, you have x moles of solute, that will be the same in the diluted solution.
Relation between molarity or volume of concentrated and diluted solutions is called, "dilution factor".
When you calculate the dilution factor: you use this formula
Molarity concentrated . Concentrated volume = M diluted . Diluted volume
M concentrated / M Diluted = Diluted volume / Concentrated volume
Answer:
En la imagen adjunta.
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!
Answer:
Hydrogen ion concentration is more conveniently expressed as pH, which is the logarithm of the reciprocal of the hydrogen ion concentration in gram moles per liter. Thus, in a neutral solution the hydrogen ion (H+) and the hydroxyl ion (OH−) concentrations are equal, and each is equal to 10−7. A pH of 7 is neutral
