Plz help have no idea...

1- CuSO4 + AgNO3 ≥ Ag2SO4 + Cu(NO3)2

(double decomposition reaction)

2- CaCL2 + Mg ≥ Ca + Mgcl2

(single replacement)

3- Combustion

5- Al2S2 ≥ Al + S

(decomposition reaction)

6- Fe2O3 + Bacl2 ≥ Bao + Fecl3

(double decomposition reaction)

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
