Chemistry
1 answer:
Daniel [21]3 years ago
8 0

The answer to your question is,

Chemical formula is "a mathematical relationship or rule expressed in symbols". For example, H2 + O = H2O. < Water.

The equation H2 + O = H2O is two elements combining together. H, hydrogen. O, Oxygen. They form together to make a new compound of elements. Water. :))

Which choice represents a pair of resonance structures? Note that lone pairs have been omitted for clarity. View Available Hint(
stepladder [879]

Answer:

A. O=C=O and O≡C−O

Explanation:

Resonance:                                                                                                                

          When the electron distribution on the molecule become uneven like one molecule have more electron compare to other.Resonance occurs due to overlap of the orbitals.When electron flow through pi system then resonance occurs.

So the option A is correct.

A. O=C=O and O≡C−O

How do you find the pressure in a container if you don't have the temperature? 
BARSIC [14]
It depends on the process.
Like for example if the process is isothermal(temperature is constant), you can use,
PV = constant or P1V1 = P2V2 where P1V1 are initial conditions and P2V2 are final.


For adiabatic process,

PV^gamma = constant or P1V1 ^gamma = P2V2 ^gamma.

where gamma = Cp
                          ------
                           Cv
Cp = specific heat at constant pressure and Cv = specific at constant volume.

Value of Gamma will be given in question.
Hope this helps!

Classify each salt as acidic, basic, or neutral? -nh4cl -ca(no32
vichka [17]
The pH of salt depends on the component acid and base that comprise them. For example, if the salt is made up of strong acid and weak base then, the salt is acidic. If the salt is formed from strong base and weak acid then, the salt is basic. For this item, NH4Cl is acidic and also Ca(NO3)2 is acidic.
