Abowling ball of 35.2kg, generates 218 kg. m/s units of momentum. what is the velocity of the bowling ball?

Answer is: velocity of the bowling ball is 6.19 m/s.

Momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction in three-dimensional space.

m(ball) = 35.2 kg; mass of a bowling ball.

p(ball) = 218 kg·m/s; momentum of a ball.

v(ball) = p(ball) ÷ m(ball).

v(ball) = 218 kg·m/s ÷ 35.2 kg.

v(ball) = 6.19 m/s; velocity of a bowling ball.

answer: the enthalpy of the overall chemical reaction is +87.88 kj or +88 kj.

according to hess's law, the overall enthalpy of a reaction is the difference between the sum of enthalpy values of all the products and the sum of enthalpy values of all the reactants.

δh(reaction) = ∑nδh(products) - ∑nδh(reactants)

δh(reaction) = [δh +δh] - [δh]

δh(reaction) = [1(-287.02) + 1(0) ] - [1(-374.9)] kj = +87.88 kj

here, δh (pcl3) = -287.02 kj, δh(cl2) = 0, δh(pcl5) = -374.9 kj

therefore, enthalpy of the overall reaction is +87.88 kj or +88 kj.
