1. a 0. 338-g sample of antimony was completely reacted with 0. 295 g of chlorine gas to form antimony chloride. determine the e
1 answer:
The empirical formula of the antimony chloride is .
Chemical formulas for compounds that simply specify the proportions of the elements they contain rather than the exact number or arrangement of atoms are known as empirical formulas. The element in the compound with the lowest whole number ratio would be this one.
Data obtained from the question
Antimony (Sb) = 0.338 g
Chlorine (Cl) = 0.295 g
Divide by their molar mass.
Sb = 0.338 / 122 = 0.0028
Cl = 0.295 / 35.5 = 0.0083
Divide by the smallest.
Sb = 0.0028 / 0.0028 = 1
Cl = 0.0083 / 0.0028 = 3
Thus, the empirical formula of the compound is SbCl₃.

The train is moving at 50 m/s and Emma is walking down the aisle with 1 m/s speed in the same direction of train. The relative velocity of Emma with respect to other passengers pf the train would be 1 m/s. This is because, the train is not moving relative to them and only emma is moving at 1 m/s. If a person observes from outside, Emma would have (50 +1) m/s = 51 m/s velocity.

Answer:
The resonant frequency of this circuit is 1190.91 Hz.
Explanation:
Given that,
Inductance,
Resistance, R = 150 ohms
Capacitance,
At resonance, the capacitive reactance is equal to the inductive reactance such that,
f is the resonant frequency of this circuit
So, the resonant frequency of this circuit is 1190.91 Hz. Hence, this is the required solution.
