Answer:
The source side of the circuit includes all parts of the circuit between the positive side battery post and the load. The load is any device in the circuit that produces light, heat, sound or electrical movement when current is flowing. A load always has resistance and consumes voltage only when current is flowing.

Answer:
The concentration of the analyte is determined by fitting the absorbance or transmittance obtained by spectrophotometric analysis of the unknown solution into the calibration curve.
Explanation:
In a calibration curve, the instrumental response (absorbance or transmittance), is plotted against the concentration of the analyte (the substance to be measured). The analyst is expected to prepare a series of standard solutions of the analyte within a range of solution concentrations close to the expected concentration of analyte in the unknown solution. The method of least squares may be used to determine the best fit of the line, thus, the concentration of the analyte. This method is only used for the determination of the concentration of coloured substances (spectrophotometry).
The number of moles of H₂ that are needed to react with 2.0 moles of N₂ is 6.0 moles
<u><em>calculation</em></u>
N₂ +3H₂→ 2NH₃
The moles of H₂ is calculated using the mole ratio
That is from equation above N₂:H₂ is 1 :3
therefore the moles of H₂ = 2.0 moles x (3/1) = 6.0 moles
<span>Given mass: 3.810 g of h2o and 13.96 g of co2.
Mass of CO2 : 13.96 g
moles of CO2 : 0.317 moles / 44.0098
moles of C : 0.317 moles
Mass of water = 3.81 g
moles of water = 0.212 moles / 18.015
moles of H = 0.423 moles X2
Hence the molar ratio C : H is 0.317 : 0.423
= 1.000 : 1.334
Multiplying by 3 on both ratios we get: 3.000 : 4.003
Therefore the empirical formula is C3H4</span>
