Answer:
6.0 moles of H₂S are produced.
Explanation:
Let's consider the following balanced equation.
2 CH₄ + S₈ → 2 CS₂ + 4 H₂S
The molar ratio of S₈ to H₂S is 1 mol S₈: 4 mol H₂S. The moles of H₂S produced when 1.5 mol of S₈ react are:
1.5 mol S₈ × (4 mol H₂S/ 1 mol S₈) = 6.0 mol H₂S
6.0 moles of H₂S are produced, when 1.5 mol of S₈ react.

heterogeneous is the mixture that we can see the difference between it's components crearly by eye do it will be the water and pool
Answer:
A- observation
B- hypothesis
C,D,E- experiment
F- conclusion
Explanation:
Lucia has just carried out the scientific process. An observation refers to paying close attention to a particular phenomenon in nature. This leads to the proposition of an intelligent guess about the observed phenomenon. This intelligent guess is called a hypothesis.
The hypothesis now guides the design of an experiment designed to confirm or disprove the hypothesis. The results of the experiment now leads to the formulation of a conclusion as Lucia has just done.
Answer:
Reactive Oxygen Species (ROS).
Explanation:
<em>Peroxide, superoxide, hydroxyl radical, singlet oxygen and alpha-oxygen conform a group of chemically reactive species containing oxygen, they are collectible known as Reactive Oxygen Species (ROS). </em>These reactive species are big contributors to the oxidative stress in the human body, they can even damage DNA.
I hope you find this information sueful and interesting! Good luck!
Answer:
Gravitational potential energy of water behind the dam
Explanation:
Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;
a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.
b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.
Hydroelectric power plant refers to a renewable source of energy used for the generation of electricity, through the use of powerful hydraulic steam turbines operating at high voltage and are being driven by the energy acquired by water falling from a height and flowing through a penstock (pipe) i.e the mechanical energy (gravitational potential energy + kinetic energy).
At a hydroelectric power plant, potential energy is changed into kinetic energy. The kinetic energy is then transformed into electrical energy.
The source of the energy that turns the turbine in the power plant is Gravitational potential energy of water behind the dam, usually from streams or rivers.
