Calculate the amount of water to be mixed (ml) with the electrolyte from the give data. Amount of metal oxide used=12 g Amount of electrolyte: 6 ml

Correct Answer: 2
We know that from Falton’s theory of electroplating, the amount of water used with metal is equal to metal oxide/electrolyte. So here it is 12/6=2.

Calculate the amount of water to be mixed (in ml) with the electrolyte from the give data. Amount of metal oxide used: 100 g Amount of electrolyte used: 10 ml

Which of the following statements are true?
Statement I Big data refers to no precise quantity, but generally refers to data in the range of Petabytes and Exabyte, i.e. billions to trillions of records, all from various sources. Big data is generated much faster. than traditional data in much larger quantities.
Statement II Big data interests industries because they are able to learn more patterns and curious variances than smaller data sets, with the capability to provide valuable insights into consumer behaviour, weather systems, financial market activity, or other phenomena.
Statement III Various departments and product lines use various applications within most organisations and store data in separate datasets. These separate databases may contain similar data, but data from one data base to another is not always consistent. This is called data silo.

a chemial is mixed 30 ml mixed , 10 ml is acid , how much ml of acid must be mixed such that a 50/50 mixure of water and acid is attend if no additional water is added

A metal oxide is reduced by heating it in a stream of hydrogen. After complete reduction, it is found that 3.15 gm of the oxide has yielded 1.05 gm of the metal. It may be inferred that the

Iron oxide reacts with which metal to give aluminium oxide?

The oxygen activity in a liquid metal can be-measured by a concentration cell using stabilised zirconia electrolyte PO2(1) | ZrO2 based solid electrolyte | PO2(2)
Where, PO2(1) is the reference oxygen pressure and PO2(2) is the oxygen pressure in equilibrium with liquid metal. If, F is Faraday constant, the EMF of the cell is equal to

Consider the figures of a metal ball and a metal ring given below.
The metal ball can just pass through the hole of a metal ring formed out of a strip. When the ball is heated it gets stuck. But when the metal is heated

Due to algal growth in a water supply reservoir in a neighborhood, the water has acquired an unpleasant taste. The compound is non-degradable, and the water utility has decided that the best way to deal with the situation is simply to flush the contaminant out of the system. The reservoir contains 11,000 m3 of water, and the proposal is to pump 300 m3/h of clean water through the system and discharge the effluent to the sewer system until 95% of the offending compound has been removed. If the reservoir is intensely mixed, how much flushing water will be required?

In case of an automobile battery, following are the reasons which will cause a defect of
1. Very high charging rate
2. High specific gravity of electrolyte
3. Freezing of electrolyte
4. Improper level of electrolyte
5. Mechanical damage due to rough handling or not fixed in the vehicle

Which of the following metal(s) produces metal oxide at a metal-scale interface?
