What is the balanced chemical equation for the reaction used to calculate ΔH∘fΔHf∘ of CaCO3(s)CaCO3(s)? If fractional coefficients are required, enter them as a fraction (i. e. 1/3). Indicate the physical states using the abbreviation (ss), (ll), or (gg) for solid, liquid, or gas, respectively without indicating allotropes. Use (aqaq) for aqueous solution. Express your answer as a chemical equation.

What is the number of moles in 15.0 g ash3?

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
