Answer:</h3>
Mole ratio of D to A is 1 : 4
<h3>
Explanation:</h3>
We are given the generic chemical equation;
4A + B → C + D
We are supposed to determine the mole ratio of D to A
What is mole ratio?
- Mole ratio is the ratio of the number of moles of reactants or products in a chemical reaction.
- We determine the mole ratio using the coefficients of reactants or products in question.
For example;
- In the equation, 4A + B → C + D, the coefficient of A is 4 while the coefficient of D is 1.
- This means, 4 moles of A reacts with 1 mole of b to produce 1 mole of C and 1 mole of D
- Thus, mole ratio of D to A is 1 : 4
Answer:
directly proportional to one another
Explanation:
Volatility refers to how quickly a substance changes from liquid to gas.
If a substance has a high vapour pressure, the substance is highly volatile. Similarly, if a substance has a low vapour pressure, then the substance is much less volatile.
This implies that volatility and vapour pressure gives a direct proportionality.
Answer:
Like all units, a mole has to be based on something reproducible. A mole is the quantity of anything that has the same number of particles found in 12.000 grams of carbon-12. That number of particles is Avogadro's Number, which is roughly 6.02x1023. 1 A mole of carbon atoms is 6.02x1023 carbon atoms

Answer:
0.629 gramos de PH3 es la máxima de cantidad que puede ser producida.
Explanation:
¡Hola!
En este caso, dado que tenemos la siguiente reacción química, la cual se puede balancear directamente:
Podemos calcular la masa máxima de cualquier producto, digamos PH3, al comparar la masa de este, que 2 g the Ca3P2 y 1 g de H2O producen por separado y de acuerdo a la estequiometría:
De este modo, infermos que solamente 0.629 gramos the PH3 pueden ser obtenidos al ser el agua el reactivo límite.
¡Saludos!
