Answer:
1. HSO³⁻(aq) + H₂O(l) → H₂SO₃(aq) + OH⁻(aq)
<u>The Brønsted-Lowry acid is H₂O and the Brønsted-Lowry base is HSO³⁻</u>
<u />
2. (CH₃)₃N(g) + BCl₃(g) → (CH₃)₃NBCl₃(s)
<u>There are no Brønsted-Lowry acids and bases in this reaction.</u>
Explanation:
According to the Brønsted-Lowry concept, when an acid (HA) and a base (B) undergoes a chemical reaction, the acid (HA) loses a proton and forms its conjugate base (A⁻), whereas the base gains (B) the proton to form its conjugate acid (HB⁺).
<em>The chemical equation for this reaction is:</em>
HA + B ⇌ A⁻ + HB⁺
Given reactions:
1. HSO³⁻(aq) + H₂O(l) → H₂SO₃(aq) + OH⁻(aq)
<u>The Brønsted-Lowry acid is H₂O and the Brønsted-Lowry base is HSO³⁻</u>
Reason: In this reaction, the acid H₂O loses a proton and forms its conjugate base, OH⁻. Whereas, the base HSO³⁻ gains a proton to form its conjugate acid, H₂SO₃.
2. (CH₃)₃N(g) + BCl₃(g) → (CH₃)₃NBCl₃(s)
<u>There are no Brønsted-Lowry acids and bases in this reaction.</u>
Reason: In this reaction, there is no exchange of proton between the acid and the base.
(1)
The health of coral colonies
The levels of carbon dioxide in the atmosphere
This is because corals are very sensitive to changes in the ocean's properties pH being included. Warmer oceans dissolves more carbon dioxide from the atmosphere hence making the waters slightly acidic. This will affect coral resulting in bleaching. This negatively affects the marine ecosystems since corals are usually at the bottom of the energy pyramid in these ecosystems.

Chlorofluorocarbons are very harmful to the environment when released into the atmosphere. They damage the ozone layer and therefore allow more UV rays from sunlight to reach the earth’s surface. They also have a greenhouse effect causing the earth’s atmosphere to warm up. This ultimately leads to global warming and climate change.
(3)
It would allow storm systems to stall in an area
Jets streams are very significant in that they influence weather patterns across the world. They are responsible for the movement of pressure systems and global air cells and their accompanying weather patterns. Because they generally sit in between cold and warm air systems they are significant in moving these air masses around. When they are weak they cause an air system to linger including storms causing excessive flooding in an area.
(4)
Absorb and re-emit infrared radiation.
Produced by human activity
Greenhouse gases do not allow infrared radiation from the earth's surface to escape back to space. Infrared is the electromagnetic wave spectrum responsible for transferring heat energy. Therefore, when left to linger in the atmosphere, they cause the greenhouse effect. This is the reason for global warming.

Air temperature –, ice
Ocean temperature – ice, a chemical isotope of <em>foraminifera</em>
Carbon dioxide levels – a chemical isotope of <em>foraminifera</em>
Kind of plants – fossilized pollen grains
Rainfall- the rings
Answer:
LEAN DOUGHS
Explanation:
A lean dough is a dough low in fat and sugar. Hard crust breads and rolls such as French and Italian breads and pizza crusts. Other white and whole wheat breads and dinner rolls. These are higher in fat and sugar and sometimes contain eggs and milk solids, because they are richer, they have a softer crust.
Answer:
The kinetic energy is increasing, and the potential energy is decreasing.
