Answer:

116g

Explanation:

Given parameters:

Mass of A  = 88g

Mass of B₂  = 28g

Unknown:

Mass of AB produced  = ?

Solution:

The reaction expression is given as:

            2A + B₂ →  2AB

According to the law of conservation of matter "matter is neither created nor destroyed but changed from one form to another".

  In retrospect;

      Mass of A + Mass of B₂  =  Mass of AB

  Now insert the parameters and solve;

  Mass of AB  = 88g + 28g  = 116g

Andre45 [30]

Answer:

The speed of the stone before it hit the river 3.00 sec later. Let v is the velocity at that instant is 45 m/s.

Explanation:

Given that, a child threw a stone straight down off a high bridge.

Initial velocity of the stone, u = 15 m/s

We need to find the speed of the stone before it hit the river 3.00 sec later. Let v is the velocity at that instant. When it come down, it is moving under the action of gravity. Using equation of motion as :

v=u+gt\\\\v=15+10\times 3\\\\v=45\ m/s

So, the speed of the stone before it hit the river 3.00 sec later. Let v is the velocity at that instant is 45 m/s.
