For the following chemical reactions, determine the precipitate produced when the two reactants listed below are mixed together. Note: Leave the answer blank if no precipitate will form. (Express your answer as a chemicalformula.) 1. Ba(NO3)2(aq) + MgSO4(aq)→ 2. HNO3(aq) + Ba(OH)2(aq)→ 3. KCl(aq) + AgNO3(aq)→ 4. (NH4)3PO4(aq) + Ni(NO3)2(aq)→ 5. Na2CO3(aq) + NH4Cl(aq)>

Iwill give extra points to who gets this right

Plz choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. is it possible for two different compounds to be made from the exact same two elements? why or why not? with a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?

Select the correct answer from each drop-down menu.describe what happens to a carbon-11 atom when it undergoes positron emission.the decay of a carbon-11 atom _1_, and this causes it to emit _2_.options for 1: > changes a neutron into a proton> changes a proton into a neutron> is hit with a neutron> reconfigures its protons and neutronsoptions for 2: > a negatively charged electron-sized particle> a positively charged election-sized particle> two atoms and several neutrons> two neutrons and two protons
