Biography

Hi! I'm Josh! I started college not knowing what I wanted to do as a career other than work in a science field. During college, I had the opportunity to work as a counselor at a summer camp and learned that I easily connected with young adults. From there, I focused my college career on becoming a high school science teacher. I graduated with Bachelor degrees in chemistry and earth science education, and later went on to earn a Masters degree in educational practices.

I have 16 years of teaching and tutoring experience in chemistry, AP chemistry, AP environmental science, earth science, and physical science. I've worked one-on-one with students, in small groups, and as a traditional classroom teacher. I have differentiated my curriculum, instruction, and pace to meet the needs of learners of all ability levels.

Write net ionic equations for the following reactions:
(a) $2 \mathrm{AgNO}_{3}(a q)+\mathrm{Na}_{2} \mathrm{CrO}_{4}(a q) \longrightarrow \mathrm{Ag}_{2} \mathrm{CrO}_{4}(s)+2 \mathrm{NaNO}_{3}(a q)$
(b) $\mathrm{H}_{2} \mathrm{SO}_{4}(a q)+\mathrm{MgCO}_{3}(s) \longrightarrow \mathrm{H}_{2} \mathrm{O}(l)+\mathrm{CO}_{2}(g)+\mathrm{MgSO}_{4}(a q)$
(c) $\mathrm{Hg}\left(\mathrm{NO}_{3}\right)_{2}(a q)+2 \mathrm{NH}_{4} \mathrm{I}(a q) \longrightarrow \mathrm{HgI}_{2}(s)+2 \mathrm{NH}_{4} \mathrm{NO}_{3}(a q)$

Two clear, colorless solutions are mixed and a white precipitate forms and settles to the bottom of the container. The diagram on the right represents the ions in solution and the solid after the reaction has occurred. Identify the spectator ions and give the balanced net ionic equation and molecular equation for the reaction.
