3. For the balanced reaction: N, (g) + 3 F2 (g) → 2 NF, (g) a. When 4.2 moles of fluorine are reacted, how many moles of NF, will be formed?

the answer is b & c i believe : )

answer seismograph;

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
