Answer:
See figure 1.
Explanation:
In this case have to take into account that <u>all structures</u> must have the formula: . If we remember the <u>general formula for alkanes</u>: if we have <u>"7" carbons (n=7)</u> we will have <u>16 hydrogens</u>. Therefore all the structures that fit with this formula are alkanes.

Answer: There are 1.78 moles in 40.0 L of He gas at STP
Explanation:
According to ideal gas equation:
P = pressure of gas = 1 atm (STP)
V = Volume of gas = 40.0 L
n = number of moles = ?
R = gas constant =
T =temperature = (STP)
Thus there are 1.78 moles in 40.0 L of He gas at STP
Answer:
La fuerza resultante o de reacción por parte de la pared es igual a cero
Explanation:
Aunque se aplique una fuerza de 13 kgf sobre la pared ,esta fuerza no es lo suficiente para que se mueva por lo tanto la pared o el objeto al que se le aplica la fuerza está en equilibrio estático.
El que el objeto o la pared esté en equilibrio estático quiere decir que la resultante de las fuerzas que actúan sobre el objeto es cero.
