Answer:
4kg=4L
Explanation:
That's because
1Kg=1L
so the relation is 1:1
so when we have
4Kg
we have to have the same ammount of litters
4L
Answer:
See explanation
Explanation:
-0.7ev = -13.6/n^2
n= 4
4--->1
4--->3, 3---> 2, 2--->1
E4-E1= -13.36(1/4^2 - 1/1^2) = 12.53 eV
E4-E3 = -13.36 (1/4^2 - 1/3^2) = 0.65 ev
E3-E2 = -13.36 (1/3^2 - 1/2^2) = 1.86 eV
E2- E1 = -13.6 ( 1/2^2 - 1/1^2) = 10.02 ev
a)
λ= 6.6 × 10^-34 × 3 × 10^8/12.53 × 1.6 × 10^-19
λ= 19.8 × 10^-26/20.048 ×10^-19
λ= 9.9 × 10^ -8 m
b)
λ= 6.6 × 10^-34 × 3 × 10^8/0.65 × 1.6 × 10^-19
λ= 19.8 × 10^-26/1.04 ×10^-19
λ= 19.0 × 10^ -7 m
Answer:
products
Explanation:
chemical reaction is the process in which atoms present in the starting substances rearrange to give new chemical combinations present in the substances formed by the reaction. These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.
Answer:
Total pressure = 22.15 atm
Explanation:
Given data:
Total pressure = ?
Volume of container = 7.85 L
Number of moles of N₂ = 4.45 mol
Number of moles of O₂ = 2.45 mol
Temperature = 307 K
Solution:
Pressure of N₂:
PV = nRT
P = nRT/V
P = 4.45 mol ×0.0821 atm.L/mol.K ×307K / 7.85L
P = 112.16 atm.L/7.85 L
P = 14.28 atm
Pressure of O₂:
PV = nRT
P = nRT/V
P = 2.45 mol ×0.0821 atm.L/mol.K ×307K / 7.85L
P = 61.75 atm.L/7.85 L
P = 7.87 atm
Total pressure = P(N₂) + P(O₂)
Total pressure = P( 14.28 atm) + P( 7.87 atm)
Total pressure = 22.15 atm
