The ball's potential energy will decrease, and its kinetic energy will increase.

Explanation:

The ball's potential energy will decrease down the slope and its kinetic energy will increase.

Kinetic energy is the energy due to the motion of a body.

 K. E = \frac{1}{2} m v²

 m is the mass of the ball

  v is the velocity of the ball.

Potential energy is the energy due to the motion of a body down slope.

It is expressed as:

   P.E = mgh

  m is the mass of ball

   g is the acceleration due to gravity of the body

  h is the height.

We can see as the body drops down the slope, the height diminishes and the velocity increases.

The decomposition of 57.0 g of Fe2O3 results in Consider the following reaction. 2Fe2O3 ---> 4Fe + 3O2 deltaH degree rxn = +
lozanna [386]

Answer:

The correct answer is option E.

Explanation:

2Fe_2O_3\rightarrow 4Fe + 3O_2 \Delta H^o_{rxn} = 824.2 kJ

Mass of ferric oxide decomposed = 57.0 g

Moles of ferric oxide decomposed = \frac{57.0 g}{160 g/mol}=0.35625 mol

According to reaction, 2 moles ferric oxide on combustion gives 824.2 kJ of heat.

Then heat given by on decomposition of 0.35625 mol of ferric oxide will be:

\frac{824.2 kJ}{2}\times 0.35625 =146.81 kJ\approx 147 kJ

So, on decomposition of 57.0 grams of ferric oxide 147 kilo Joules of heat was released.
