Answer:
1027.9 mL
Explanation:
Formula P1 x V1 / T1 = P2 x V2 / T2
Fill in what you know
Pressure is constant so no need to put that in making the formula
V1 / T1 = V2 / T2
Voulme 1= 950 mL
Volume 2= ?
Temperature 1 = 25 C
Temperature 2 = 50 C

Answer: I have sent the notes to u private
Explanation:
Compounds. They both have more than one element in them
Answer:
32. Opcion E
Explanation:
ZO₂ podemos entenderlo como dióxido de Z
1 mol de ZO₂ contiene 1 mol de Z y 2 moles de O₂ por lo que si la masa molar es de 64 g/mol, podemos plantear lo siguiente
Masa de Z + 2 masa de O = 64 g/mol
Sabemos que la masa del oxígeno es 16 g/mol
x + 2. 16 g/mol = 64 g/mol
x = 64 - 32 → 32 g/mol
La masa atómica coincide con la masa molar, por lo tanto la masa atomica de Z es 32.
Answer:
.0388 atm
Explanation:
Since temperature is not given , we assume that it is constant . So we can apply Boyle's law . According to it
P₁ V₁ = P₂ V₂
P₁ and V₁ are pressure and temperature initially and P₂ and V₂ are pressure and volume finally .
Putting the given values
.12 x 2.31 = 7.14 x P₂
P₂ = .12 x 2.31 / 7.14
= .0388 atm .
