In all the three cases we don't get any result because there is no reducing agent to obtain result.

A piece of metal is dropped into a test tube of light-blue liquid. The piece of metal immediately starts fizzing and dissolving, and you can sense the heat radiating from the test tube even when your finger is an inch away. 2) A spoonful of salt is added to a beaker of water, and stirred. The salt dissolves completely in the water. 3) Two clear liquids in separate test tubes are mixed in a beaker. Within a minute, you observe...

A U tube of uniform oss section is party filled with water (density Av). Another liquid of density ρ that does not mix with water is poured no one side unti it stands a distance d above the original water level. The water level rises by a distance I in the other arm (see the figure below). Find the density of the liquid relative to that of water in terms of d and I Pw

7. A U-tube is filled with water until the liquid level is 29 cm above the bottom of the tube. An oil of specific gravity 0.80 is now poured into one arm of the U-tube until the level of the water in the other am, of the tube is 34 cm above the bottom of the tube. Find the level of the oil-water and oil-air interfaces In the other arm of the tube. cm (oil-water) cm (oil-air)

A liquid (NOT WATER) is passed through a tube with a square cross section of 0.01m x 0.01m at a Reynolds number of 2,000. The liquid has a Prandtl number of 1, a thermal conductivity of 0.2 W/mK, and a heat capacity of 4,000 J/kg*K. Simultaneously, air is blown at a speed of 20 m/s and a temperature of 25°C over the outside of the tube such that the flow is perpendicular to one of the square sides. The liquid...

Liquid water coats an active (growing) icicle and extends up a short, narrow tube along the central axis (see the figure below). Because the water-ice interface must have a temperature of 0 C, the water in the tube cannot lose energy through the sides of the icicle or down through the tip because there is no temperature change in those directions. It can lose energy and freeze only by sending energy up (through distance L) to the top of the...

What does a positive result of a bacterial "catalase" test look like? What's in it that makes it look like so? Select one: O a. The small clump of bacteria appear at the bottom of the tube of test broth. The color of the broth turns deep red, showing acidic substance is being secreted by the bacteria b. The small clump of bacteria makes bubbles/ foams, and it is oxygen gas that's in the bubbles O c. The agar turns...

Liquid water flows in an ASTM B75 copper tube at a mass flow rate of 3.6 g/s. The water enters the tube at 40°C, and the tube surface is subjected to a constant heat flux at a rate of 1.8 kW. The tube is circular with an inner diameter of 25 mm and a length of 3 m. The maximum use temperature for ASTM B75 copper tube is 204°C. Would the surface temperature of the tube exceed the maximum use...
