Critical Thinking
Evaluate: What type of bonding does a material most likely have if it has a high melting point, is solid at room temperature, and easily dissolves in water?

Explain the following statement: All compounds are substances, but not all substances are compounds.

Suppose you have a found an unknown substance in a laboratory. It has the formula H2O2 written on the bottle. Is it water? How do you know?

last one :H202 is hydrogen peroxide so its not water it is simmilar but its NOT water.

i dont know the other ones.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
