Calculate the mass in grams of Ni3(PO4)2 that precipitates when 23.65 g NiCl2 is mixed with 109.2 mL of 0.500 M Na3PO4. 3 NiCl2(aq) + 2 Na3PO4(aq) --> Ni3(PO4)2(s) + 6 NaCl(aq)

7. what temperature is need to just dissolve 50 g of nh4cl in 75 g of water? '

Brainliesttt me asap! the below reaction can be categorized as more than one type of reaction. which reactions are these, and what are the types of reactions?

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
