The conjugate acid in the reaction described in hcl(g) + nh3(aq) → nh4+(aq) + cl- (aq) is

The conjugate acid in the reaction described in HCl(g) + NH3(aq) → NH4+(aq) + Cl- (aq) is NH4+.

Explanation:

the answer is false because not all countries have geysers under their crust. for example, iceland uses geothermal energy because it is available every in their country.  

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
