Answer:
1258 grams of AgN03
Explanation:
We calculate the weight of 1 mol of AgN03:
Weight 1 mol AgN03= Weight Ag + Weight N +( Weight 0)x3=108g+ 14g+16gx3=170 g/mol
1 mol----170 g AgN03
7,4mol---x= (7,4 mol x170 g AgN03)/1 mol=1258 g AgN03
Explain what happens to the temperature of ice while it melts
Answer:
Because only certain photons are emitted, we know that only certain energy changes are occurring. This means that the hydrogen atom must have certain discrete energy levels. Excited hydrogen atoms always emit photons with the same discrete colors (wavelengths). They never emit photons with energies between those shown. So we concluded, all hydrogen atoms have the same set of discrete energy levels.
