Answer:The reactants are Oxygen and iron.

The product is Iron oxide.

Explanation:

When iron and oxygen reacts with each other produce iron oxide which reddish brown in color. This reddish brown iron oxide is often refereed to as Rust.

4Fe+3O_2\rightarrow 2Fe_2O_3(\text{reddish brown})

The Reactants are iron and oxygen.

The product is iron oxide

djyliett [7]

Answer:

u= 20.09 m/s

Explanation:

Given that

m = 0.02 kg

M= 2 kg

h= 0.2 m

Lets take initial speed of bullet = u m/s

The final speed of the system will be zero.

From energy conservation

1/2 m u²+ 0 = 0+ (m+M) g h

m u²=2 (m+M) g h

By putting the values

0.02 x u² = 2 (0.02+2) x 10 x 0.2       ( take g=10 m/s²)

u= 20.09 m/s
