Let 16.2 grams of aluminum completely react with HCl solution a) Write the equation for the reaction
b) Calculate the volume of H2 gas produced at dtc
c) If the above volume of H2 is used to reduce 58 grams of Fe3O4, which substance is left over after the reaction and how many grams are left over?
d) Calculate the mass of Fe produced.

0.66y = 0.9x + 0.48 if y has a value of 108.45 what is the value of x?

When hydrochloric acid reacts with potassium hydroxide solution, the following reaction occurs. hcl (aq) + koh (aq) h2o (l) + kcl (aq) the reaction gives off heat energy, so it is an reaction.

Consider a culture medium on which only gram-positive organisms such as staphylococcus aureus colonies can grow due to an elevated nacl level. a yellow halo surrounds the growth, indicating the bacterium fermented a sugar in the medium, decreasing the ph as a result and changing the color of a ph indicator chemical. this type of medium would be referred to as a differential and enrichment culture.
