Subtract the value of the second pair from the value of the first pair, or 18 - 8 = 10. Our determinant equals 10. Once again, determine the sign dictated by the location of the element you eliminated. In this case, the sign is +, so we would use 10. Next, let's find the cofactor of 5.
Answer: The outermost zone of a flame is the hottest zone. Due to this, goldsmith uses the outermost zone of a flame for melting gold and silver. Question: 11. In an experiment 4.5 kg of a fuel was completely burnt.
After the sample has been applied to the paper and the paper has been equilibrated with the buffer. The current is switched on. Commonly used buffers are, The device providing stable voltage (or) current is available.) Quantitative estimation: The color density of the zone may be multiplied with the area of the zone and the resulting value would be a rough estimate of the concentration of the component. Paper Electrophoresis is one of the zone electrophoresis. This is very important method in all laboratories.
