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.
Which of the following is true of folded mountains, fault-block mountains, and volcanic mountains?
Form from the buildup of lava and ash
Form only at boundaries between two oceanic plates
Form only at boundaries between two continental plates
Form at both convergent and divergent plate boundaries
Answer:
Here are the following answers to the five questions:
(1) "Form only at boundaries between two continental plates."
(2) "A fault-block mountain"
(3) "Island arcs form when hot, fluid rock rises through thin spots in Earth's crust, whereas hotspot volcanoes form when two oceanic plate boundaries push against each other until subduction happens and the plates partially melt."
(4) "The fault plane runs from the top of the rock to the bottom of the rock at an angle greater than 45 degrees."
(5) "Segments of Earth's crust bent and doubled over, and moving wind and water gradually shaped the rock into gently sloping domes."

Explanation:
find the molarity of 4.9 g of h2so4 in 400 ml solution
The molarity of a solution that contains 4.9 g of [tex]H_2SO_4[/tex] in 400 ml of solution would be 0.12465 M
Define molarity of a solution.
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.
Mathematically,
[tex]Molality = \frac{Moles \;solute}{olume \;of \;solution \;in \;litre}[/tex]
Mole of 4.9 g [tex]H_2SO_4[/tex]
= [tex]\frac{mass}{molar \;mass}[/tex]
= [tex]\frac{4.9 g}{98.08}[/tex]
= 0.0499
[tex]Molality = \frac{Moles \;solute}{ olume \;of \;solution \;in \;litre}[/tex]
[tex]Molality = \frac{ 0.0499}{0.4}[/tex]
= 0.12465 M
Hence, the molarity of a solution that contains 4.9 g of [tex]H_2SO_4[/tex] in 400 ml of solution would be 0.12465 M.

Draw a complete enthalpy diagram for the following reaction: 4Na(s) + O2(g) → 2Na2O(s). H=-178kJ
The enthalpy change of the given reaction is negative, so the reaction is an exothermic reaction.
What is enthalpy change of a reaction?Enthalpy change of a reaction is the energy changes that occur when reactant molecules form products.
Enthalpy is the heat content of a substance.
When enthalpy change is positive, the heat content of the product is greater than that of the reactant and the reaction is an endothermic reaction.
Whereas, when enthalpy change is negative, the heat content of the reactant is greater than that of the product and the reaction is an exothermic reaction.
Therefore, since the enthalpy change of the given reaction is negative, the reaction is an exothermic reaction.

From the calcuation, the percent ionic character of the bond is 70%
What is percent ionic character?The term percent ionic character has to do with the degree of ionic bonding that is contained in a compound. It can be estimated from the electronegativity of each element.
We can use the formula; 100(1 - e^(-ΔEN² / 4))
EN = χB − χA * 100/1
EN = 3.5 - 1.5 = 1
