T eg(1) : 97.5°C, T eg(2): 98.5°C, T eg(3): 99.2°C
∆T water(1): -2.5°C, ∆T water(2): -1.5°C, ∆T water(3): -0.8°C
∆T metal(1): 77.5°C, ∆T metal(2): 80.5°C, ∆T metal(3): 80.2°C.
ft= (m1 cp1 t1 + m2 cp2 t2 + .... + mn cpn tn) / (m1 cp1 + m2 cp2 + .... + mn cpn) (1)
where,
1000g = 1kg
ft(t eg)= final mixed temperature (°C)
m = mass of substance (kg)
cp = specific heat of substance (J/kg°C)
t = temperature of substance (°C)
Answer:
Esto significa que la masa en las moles de plomo es mayor que en las de plata.
Explanation:
Las moles de los átomos representan la cantidad de átomos presentes. Para saber la masa de los átomos debemos convertir las moles a gramos usando el peso molecular de cada uno de los átomos (207.2g/mol para el plomo y 107.82g/mol para la plata).
La masa de plomo en 300 moles es:
300 moles * (207.2g / mol) = 62160g de plomo
Y la masa de plata es:
300 moles * (107.82g / mol) = 32346g de plata
<h3>Esto significa que la masa en las moles de plomo es mayor que en las de plata</h3>
Answer:
Water is wet, in the sense of being a liquid which flows easily, because its viscosity is low, which is because its molecules are rather loosely joined together.
Explanation:
Answer: The partial pressure of neon in the mixture is 263 mm Hg
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given : 
=total pressure of gases = 815 mm Hg
= partial pressure of helium = 201 mm Hg
= partial pressure of nitrogen = 351 mm Hg
= partial pressure of Neon = ?
putting in the values we get:
The partial pressure of neon in the mixture is 263 mm Hg
