The mixing of which pair of reactants will result in a precipitation reaction? the mixing of which pair of reactants will result in a precipitation reaction? li 2so4(aq) + ba(no3)2(aq) nano3(aq) + nh4cl(aq) csi(aq) + naoh(aq) hcl(aq) + ca(oh)2(aq)

 Li 2SO4(aq) + Ba(NO3)2(aq) .

Explanation:

Given that

Li 2SO4(aq) + Ba(NO3)2(aq)

NaNO3(aq) + NH4Cl(aq)

CsI(aq) + NaOH(aq)

HCl(aq) + Ca(OH)2(aq)

From the above given reaction ,the reaction between  Li 2SO4(aq) + Ba(NO3)2(aq) will result in a precipitation reaction and BaSO4 will be precipitate.

So the answer is  Li 2SO4(aq) + Ba(NO3)2(aq) .

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
