Answer:
it opposes motion. the object would continue to slide forever if not stopped by another object.
Temperature? Magma at different temps has different densities, less dense magmas rise to the top
A buffer is usually composed of either:
- a weak base combined with its conjugate acid, or
- a weak acid combined with its conjugate base
Now, examining each of the choices:
1- KOH and NH3: since they are both bases, thus this mixture is not a buffer
2- HBr and NaCl: since HBr is a strong acid while NaCl is the salt of another different acid, thus this mixture is not a buffer
3- HCl and HBr: these are both considered to be strong acid, thus this mixture is not a buffer
4- HCHO2 and NaCHO2: as for HCH02, it is considered a weak base while NaCHO2 is considered its conjugate base, thus this mixture is a buffer
Answer:
g/cm^3
Explanation:
Density= m/v
gram is a measurement of mass
cm^3 is a measurement of volume
Hope this helps:) Have a good day!
