kate-douglas-wigginhad a deep love for young children, was in the forefront of the kindergartenmovement, headed the West Coast's first free kindergarten, and started a teacher-training program in California. But, when she was 25 years old, she got married and, as was customary in those days, she had to quit teaching. So Wiggin turned her energies to writing, donating much of the income from her publications and lectures to children's causes. In 1903, Wiggin's most popular novel, rebecca-of-sunnybrook-farm, was published. Two years later she had another bestseller, Rose O' the River.
No. They are covalent/molecular compounds.
KBr APEX:)
CaO, K2CrO4 and Na2HPO4 are all ionic compounds
Ionic compounds: NaCl, KOH, CuSO4, etc. Any compound containing a metal and a non-metal. In ionic compounds, metals have positive ions (they lose electrons to the non metal) and non-metals have negative ions (as they gain electrons from the metal) Covalent compounds: CH4, BF3, NH3, all hydrocarbons/ all compounds containing only non-metals.
AgI and AgBr are not as souble as AgCl or AgF so it takes a higher concerntration of NH3 to dissolve it. So that do dissolve in Nh3 but the solution you are using needs to be more concertrated.
E. CH2O, H2S, NH3
CaO is the only ionic
No. They are covalent/molecular compounds.
KBr APEX:)
Nitrogen and hydrogen don't form ionic compounds. they form only covalent compounds as in ammonia (NH3) or hydrazine (H2N-NH2) etc
CaO, K2CrO4 and Na2HPO4 are all ionic compounds
Ionic compounds: NaCl, KOH, CuSO4, etc. Any compound containing a metal and a non-metal. In ionic compounds, metals have positive ions (they lose electrons to the non metal) and non-metals have negative ions (as they gain electrons from the metal) Covalent compounds: CH4, BF3, NH3, all hydrocarbons/ all compounds containing only non-metals.
it will not dissolve NH3 in poler molecules
AgI and AgBr are not as souble as AgCl or AgF so it takes a higher concerntration of NH3 to dissolve it. So that do dissolve in Nh3 but the solution you are using needs to be more concertrated.
SrO, LiI, NH4Cl
NH3 is its own compound.The elements in NH3 are nitrogen and hydrogen.
Molecular Eq HC2H3O2(aq) + NH3(aq) -> NH4+(aq) + C2H3O2-(aq) Ionic Eq H+(aq) + C2H3O2-(aq) + NH3(aq) -> NH4+(aq) + C2H3O2-(aq) Net Ionic Eq H+(aq) + NH3(aq) -> NH4+(aq)
