How can we prevent coral reefs from dying in the first place?
Explanation:
1. Reduce your carbon footprint
Carbon emissions also increase ocean acidity, which can impact corals and the species that depend on them.
Walking, biking, riding public transportation and carpooling are all ways you can reduce your carbon footprint
2. Conserve water to reduce pollution
All water winds up in the ocean, and pollution drives much of the damage to reefs. And runoff is what carries nutrients and contaminants into the sea.
Using less water can help minimize these impacts.
3. Get engaged
Through civic and political engagement, you can help shape your community in ways that reduce negative impacts on coral reefs. Volunteering, voting and running for public office are all ways you can become more engaged and magnify your impact on a wide range of issues.
4. Support sustainable fishing
Overfishing has a dramatic impact on coral reefs. By making informed choices about the fish you purchase and eat, you can contribute greatly to ocean health.
5. Support sustainable development and tourism
By doing research, speaking out and making informed choices when you visit tropical reefs, you can make a big impact
6. Help inform the public
Educating others about the crisis facing coral reefs is a vital part of building support, engagement and the political will to fight the human-caused pressures that are devastating reef ecosystems.

According to the kinetic-molecular theory, the collision between two ideal gas particles is a result of
Answer:
Neither Attraction Nor Repulsion
Explanation:
To start off,
Kinetic Molecular Theory:
A theory that describes the behavior, interaction, and movement of gas molecules; based on the idea that particles of matter are always in motion; the relationship between the microscopic qualities and the macroscopic qualities of a gas.Repulsion:
Repulsion in chemistry stands for the force which exists between two bodies that have the same electric charge or the same magnetic polarity, this force tends to repel the bodies and separate them from each other.Attraction:
The attraction of the negatively charged electrons that are circling the nucleus and the positively charged protons that are inside the nucleus provokes a pill that creates a chemical bond.To finish,
Gas particles move at random, which means there are no attractive forces between them or in their surroundings. The entire kinetic energy of two particles is preserved when they collide.
Answer:
Neither attraction nor repulsion.

17. Explain How is a change in oxidation number related to the process of oxidation and reduction?
Answer:
Explanation:
A change in oxidation number represents a transfer of electrons between atoms/ions. This is what happens during oxidation and reductions, where electrons are gained and lost (respectively).
Atoms of arsenic (As) are often added to silicon (Si) in a process called doping to change the conductivity of the silicon. How does the addition of arsenic change the conductivity of silicon?
An atom of arsenic has one fewer valence electron and more electron shells than an atom of silicon, so the conductivity decreases because the arsenic atom gains an electron.
An atom of arsenic has one more valence electron and more electron shells than an atom of silicon, so the conductivity decreases because the arsenic atom loses the electron.
An atom of arsenic has one fewer valence electron and fewer electron shells than an atom of silicon, so the conductivity increases because the arsenic atom gains an electron.
An atom of arsenic has one more valence electron and more electron shells than an atom of silicon, so the conductivity increases because the arsenic atom loses the electron.
Answer:
B.) An atom of arsenic has one more valence electron and more electron shells than an atom of silicon, so the conductivity decreases because the arsenic atom loses the electron.
Explanation:
Silicon is located in the 3rd row and 14th column in the periodic table. Arsenic is located in the 4th row and 15th column in the periodic table. This means that arsenic has one more valence electron than silicon. Since arsenic is located one row down from silicon, its valence electrons occupy higher energy orbitals.
Silicon maintains a crystal-like lattice structure. Each silicon atom is covalently connected to assume this shape. When silicon gains one extra electron from arsenic, it experiences n-type doping. This new electron is not tightly bound in the lattice structure. This allows it to move more freely and conduct more electricity. This can also be explained using band gaps. Silicon, which previously had an empty conduction band, now has one electron in this band. This lowers the band gap between the conduction and valence bands and increases conductivity.

What was in Flint's water that caused 12 people to die?(1 point)
lead
total triahalomethanes
Legionella pneumophila
Escherichia coli
The presence of lead in Flint's water is what caused the death of 12 people.
Option A.
What was in Flint's water?The Flint water crisis started in 2014 when the city of Flint, Michigan, switched its water source from Lake Huron to the Flint River as a cost-cutting measure.
The water from the Flint River was more corrosive and caused lead to leach from the pipes, contaminating the drinking water. This led to high levels of lead in the drinking water, which is a potent neurotoxin that can cause a variety of health problems, particularly in children.
The contamination also led to an outbreak of Legionnaires' disease, a severe form of pneumonia, which was linked to at least 12 deaths in the area.

Answer:
Primary consumers are herbivores, feeding on plants
Explanation:

Explanation:
Sam and Albert reacted 3.5 moles of hydrogen gas with an excess of oxygen and had a percent yield of 85%. How many moles of water did they actually produce
The mole of water Sam and Albert produced would be 3.5 moles
Mole ratioFrom the balanced equation of the reaction:
[tex]2H_2 (g) + O_2 (g) --- > 2H_2O (l)[/tex]
The mole ratio of hydrogen to water is 1:1.
Thus, if 3.5 moles of hydrogen gas is reacted with excess oxygen, 3.5 moles of water will also be produced.
