as per the reaction we have
so here 1 mole of H2 react with 1 mole of O2 and give 1 mole of H2O2 as the product
now we will find the moles of given reactant
moles of H2
moles of O2
so here both present in 1 mole each hence the product will also formed 1 mole
so here we have
H2O2 will form
so mass of the product
mass = moles* molecular mass
so the product mass will be 34 g
Answer
given,
at time t = 10 s moving from left to right speed of particle = 5 m/s
at t = 20 s moving from right to left speed of particle is = 8 m/s
a) acceleration
a = -1.3 m/s²
b) using equation of motion
v = u + at
5 = u - 1.3 × 10
u = 5 + 13
u = 18 m/s
c) v = u + at
0 = 18 - 1.3t
t = 13.85 s
