I need help balancing these equations. CCl + K2CrO4 ==> Cl2CO + CrO2Cl2 + KCl & K2CrO4 + C ==> K2CO3 + K2O + CO + Cr2O3

3. Place the following list of compounds into as many categories (boxes) as appropriate. It's probably easier to go substance-by- substance instead of category-by-category (e.g. take NaCH3COO and place it into as many categories as possible). NaCH;COO, HNO3, PBB12, CH,CH2OH, AgNO3, CH;COOH, Fe(NO;)3, C,H1206, KOH, Zn(OH)2, H2S, CACO3, (NH4);PO4, Li;PO4, H2CO3, H2SO4, HCOOH, CSOH, NH3, Na2SO4 Strong acids: Strong electrolytes: Weak acids: Weak electrolytes: Nonelectrolytes: Strong bases: Insoluble:

is this right?

A formula for compounding state qs ad 250 ml. This expression means

BaCO3 - Ba2+ + CO3? reaction was given. It is known that the carbonate anion is hydrolyzed in [HCO ][OH] [co? ] CO3- + H20 = HCO; + OH Kb1 and [H2CO3][OH¯] [HCO3] HCO; + H2O = H;CO3 - OH- Kb2 = form. Since Ka1 = 1.44x10-7, Ką2 = 4.7x10-11 and KspBaco3 = 5.1x10-9, calculate the solubility of BaCO; salt at pH = 8 and 12 depending on the pH value.

Potentially Useful Information Spectrochemical Series: | < Br < SCN¯ < Cl° < NO3¯ < F° < OH° < C2O4²¯ ~ H2O < NCS° < NH3 < en < PPH3 く A student has three test tubes containing a metal (M) nitrate solution M(NO3)2 (aq) (where "M" represents a generic transition metal). The student adds aqueous ammonia (NH3) to one test tube, aqueous hydrochloric acid (HCI) to the second tube, and nothing more to the third tube, but forgets to label the tubes. After this, one test tube contains a red solution, one an orange solution, and one a yellow solution. Note: This metal, M, would follow the same rules that we used for Cu(II), Ni(II), and Co(II). The Jahn-Teller Effect does not apply. Complete each statement or answer each question below about the solutions in the three test tubes. The aqua complex causes less splitting of the d orbitals of the metal than the... ammonia complex. O chloro complex.
