Answer:
90.5g de NOCl en 2500 g de solución blanqueadora.
Explanation:
Una solución de concentración 3.62% en peso de hipoclorito en una solución blanqueadora contiene 3.62g de NOCl por cada 100g de solución. Con esta relación, podemos encontrar la masa de NOCl en 2500g de solución, así:
2500g de solución * (3.62g NOCl / 100g solución) =
<h3>90.5g de NOCl en 2500 g de solución blanqueadora.</h3>
The total ball pressure is sum of gauge pressure and atmospheric pressure
We know that atmospheric pressure = 101.325 kPa
so the total ball pressure = 61 kPa + 101.325 kPa = 162.325 kPa
Now we will use ideal gas equation as
PV = nRT
P = pressure = 162.325 kPa
V = 5.2 L
R = gas constant = 8.314 kPa L / mol K
T = 32 C = 273.15 + 32 = 305.15 K
n = moles = ?
Moles = PV / RT = 162.325 kPa X 5.2 / 305.15 X 8.314 = 0.332 moles
Metalloids show the properties that are midway between metals and non metals. Silicon is a metalloid and for this reason it is abundantly used in computer chip industry. Silicon and other metalloid elements are building blocks of electronics because they are cheap, easily available, economical.
The only list containing molecules is list #4
NaCl, N2, and H2O are all made up of more than one element, making them molecules. The other lists contain an element. Mg, He, and Fe are elements, not molecules.
Hope this helps!
