“A class C fire is an energized electrical fire. ... “Class C” is a term that distinguishes a fire from class A and class B fires. Class A is a category for fires consuming a source like fire or wood that can be extinguished with water, and class B fires are fueled by flammable liquids like gasoline.”
1. According to Rutherford and soddy's law of Beta emission:
3. According to Rutherford and soddy's law of Alpha emission:
4. The process in which two or more light nuclei are combined to form a single nucleus with the release of tremendous amount of energy is called a nuclear fusion. The inner core of Sun is at very high temperature and is suitable for fusion. In fact the source of energy of Sun and other stars is nuclear fusion reactions.
Answer: 6. Rb Cl
Because, as the electronegativities of the elements, Rb and Cl, indicate this an ionic compound. Meaning that the elements are as ions ( Rb+ Cl-)., which in liquid (molten) state are charges that move freely, making the compound a good conductor of electricity.
Answer:
Value of for the given reaction is 7.7
Explanation:
Where represents solubility product
For the given reaction, (concentration of pure solids remain constant during reaction. Hence their concentration is taken as 1 to exclude them from equilibrium constant expression)
So,
or,
Hence option (B) is correct
