why PH scale range is 14? why it is not less or not greater
than 14? solution of HCl or hydrogen containing liquid has
a PH. but if the solution is KMnO4 here not hydrogen power
does it PH? explain plz....
I had applied for the post of officer trainee so plz if u
have any papers both technical or aptitude plz inform me on
X is strong but has a very low density (1% of traditional
earth materials.) and hence
light weight. It is a recyclable material. The compression
behaviour of X is strain rate
dependent. Higher strain rates result in higher initial
modulus and higher
compression strength. It can also withstand unlimited
number of cycling loading
provided the repetitive loads are kept below 80% of the
compressive strength. The
internal structure of the material includes air-traps which
make it poor heat
conductor. X is non- biodegradable and chemically inert in
both soil and water. Most
acids and their water solutions do not attack it; however
strong oxidizing acids do.
Solvents which attack X include esters, ketones, ethers,
aromatic and aliphatic
hydrocarbons and their emulsions, among others. It does not
bacterial/fungal growth as well .It also has significant
acoustic properties and
effectively reduces the transmission of airborne sound. X
is combustible and should
not be exposed to open flame or other ignition sources.
Combustion products are
carbon monoxide, carbon dioxide, water and soot. Long-term
exposure to sunlight
causes yellowing and a slight embrittlement of the surface
due to ultraviolet light. X
is able to withstand the rigours of temperature cycling,
