Answer:

Kinetic energy to mechanical energy, and mechanical energy to electrical energy.

Explanation:

From the Law of conservation of Energy, which state that energy can neither be created nor destroyed but can be transformed from one form to another. Energy transformation is essential in science and technology, in the process of generating electricity from dams and nuclear power plants

some of the energy transformations are the same, the energy transformations occur in both dams and nuclear power plants is Kinetic energy to mechanical energy, and mechanical energy to electrical energy. Kinectic energy is the energy in motion which means the dams is a running water and posses a Kinectic energy then it's is been convert to mechanical energy (which is the macroscopic energy) then to electrical energy by producing light.

How many liters of CO2 gas can be produced at 30.0 °C and 1.50 atm from the reaction of 5.00 mol of C3H8 and an excess of O2 acc
lbvjy [14]

Answer:

249 L

Explanation:

Step 1: Write the balanced equation

C₃H₈(g) + 5 O₂(g) → 3 CO₂(g) + 4 H₂O(g)

Step 2: Calculate the moles of CO₂ produced from 5.00 moles of C₃H₈

The molar ratio of C₃H₈ to CO₂ is 1:3. The moles of CO₂ produced are 3/1 × 5.00 mol = 15.0 mol

Step 3: Convert "30.0°C" to Kelvin

We will use the following expression.

K = °C + 273.15

K = 30.0°C + 273.15 = 303.2 K

Step 4: Calculate the volume of carbon dioxide

We will use the ideal gas equation.

P × V = n × R × T

V = n × R × T/P

V = 15.0 mol × 0.0821 atm.L/mol.K × 303.2 K/1.50 atm

V = 249 L

Given the reaction: 4NH3 + 502 4NO + 6H2O
Ainat [17]

Answer:

\frac{4}{5} moles

Explanation:

The reaction equation is given as:

      4NH₃   +  5O₂  →  4NO  +  6H₂O

The number of moles of O₂ that completely reacted is given as 1 mole

To solve this problem, we are going to use a stoichiometric approach from the balanced reaction equation:

         5 moles of O₂ will react completely to produce 4 moles of NO

        1 mole of O₂ will therefore react to produce  x mole of NO

               5x  = 4

                 x  = \frac{4}{5} moles of NO

Are there chemical reactions happening in our home
White raven [17]
Yes, remember a chemical reaction is whenever one or more substances combine together to form a different substance. So whatever you put together and form something new is called a chemical change/reaction. Examples such as rusting of Iron, expired milk(going sour), Baking cake and many more to think about
Hope it helps
