Can someone please do these two problems for me! ill mark brainliest !! balance the equation:
__H2O2 → ___ H2O + ___O

(this is a chart)
reactant product
1. 1.
2. 2.

balance the equation:
_N2 + __H2 -> __NH3

reactant product
1 1
2 2

Acar traveling at 22 m/s starts to decelerate steadily. it comes to a complete stop in 15 seconds. what is it’s acceleration?

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
