Hey there!
For this we can use the combined gas law:
We are only working with pressure and temperature so we can remove volume.
P₁ = 2 atm
T₁ = 27 C
P₂ = 2.2 atm
Plug these values in:
Solve for T₂.
Convert this to kelvin and get 302.85 K, which is closest to B. 330 K.
Hope this helps!
Answer:
Ba has the largest atom size
Answer:
97.0%m/m es la concentración de la solución
Explanation:
El porcentaje masa/masa (%m/m) se define como 100 veces el radio entre la masa de soluto (300g de HCl) y la masa de la solución. Para hallar la masa de la solución debemos hallar la masa del agua (Solvente) haciendo uso de la ecuación del volumen de un cono. Con el volumen del cono podemos hallar la masa del agua haciendo uso de la densidad, así:
<em>Volumen:</em>
Volumen Cono = π*r²*h / 3
Donde r es el radio = 0.300m
h la altura = 5m
Volumen = π*(5m)²*0.300m / 3
7.85m³
<em>Masa Agua:</em>
7.85m³ * (1.2g / m³) = 9.42g Agua
<em>Masa solución:</em>
300g HCl + 9.42g Agua = 309.42g Solución
<em>%m/m:</em>
300g HCl / 309.42g * 100 =
<h3>97.0%m/m es la concentración de la solución</h3>
Hydropower can affect fish and other marine life which is the true statement and is denoted as option C.
<h3>What is Hydropower?</h3>
This is the process in which water energy is converted into electrical energy through the use of dams and turbines.
When the dams are created, it blocks the path of marine activities and limits them to certain activities such as reproduction.
