HELP NEEDED ASAP What mass of Al is produced when 0.500 mole of Al2 S3 is completely reduced with excess H2? (At. Masses of Al=27, S=32, H=1)
Select one:
a. 13.5 g
b. 27.0 g
c. 2.7 g
d. 54.0 g

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
