Explain how the digestive/excretory system is similar to a recycling center
CaHeK987 [17]

Answer:

The digestive system is a system where our body breaks down food to acquire important nutrients. This is the same as your local recycling center because they collect and breaks the plastic down to be reused into recycled products.

The excretory system is a system where we remove excess unnecessary materials. This can be the same as the recycling center because they remove unnecessary materials (such as trash that is not meant to be recycled).

When the following equation is balanced with lowest whole-number coefficients, what is the coefficient for NO(g)? ___NH3(g) + __
inn [45]

Answer:

Coefficient in front of the NO in the balanced equation - 4

Explanation:

The unbalanced reaction is shown below as:-

NH_3+O_2\rightarrow NO+H_2O

On the left hand side,  

There are 1 nitrogen atom and 3 hydrogen atoms and 3 oxygen atoms

On the right hand side,  

There are 1 nitrogen atom and 2 hydrogen atoms and 2 oxygen atoms

Thus,  

Right side, H_2O must be multiplied by 6 and NO by 4

Left side, O_2 is multiplied by 5 and NH_3 by 4 so to balance the whole reaction.

Thus, the balanced reaction is:-

4NH_3+5O_2\rightarrow 4NO+6H_2O

<u>Coefficient in front of the NO in the balanced equation - 4</u>

Predict whether the following reactions are spontaneous.
melomori [17]

Answer:

1. spontaneous

2. spontaneous

3. Not Spontaneous

4. Not Spontaneous

Palladium and Sn^4+ can be reduced by hydrogen.

Explanation:

If we look at the electrochemical systems represented above, we will notice that in the first two cells, the metal should be reduced looking at the positive electrode potential of the process. This means that hydrogen can reduce the both metals. Electrons flow from the H2(g)/H^+(aq) half cell to the metal/metal ion half cell.

Similarly, when the standard electrode potential is negative, electrons flow from the metal/metal ion electrode to the hydrogen electrode.

Based on the reaction equations, a process is spontaneous if it gives a positive E°cell hence the answers above.
