What three strategies that can be used to protect coral reefs from ocean acidification?

2. Aspirin is absorbed into the blood through the cells lining the stomach and the small intestine. Absorption requires passage through the plasma membrane, the rate of which is determined by the polarity of the molecule: charged and extremely polar molecules pass slowly, whereas neutral and hydrophobic ones pass rapidly a. The pH inside the stomach is around 2.0 and the pH of the contents of the small intestine is about 6.0. Which of the following statements is correct: i. The small intestine has 3 times lower [H] than the stomach. ii. The small intestine has 4 times lower [H ] than the stomach iii. The small intestine has 3,000 times lower [H] than the stomach iv. The small intestine has 10,000 times lower [H] than the stomach. b. The pKa of aspirin is 3.5. Draw the predominant form of aspirin and its overall charge (-1,0 or +1) when it is in the stomach or in the small intestine: Small Intestine (pH= 6.0): Stomach (pH 2.0) Overall Charge: Overall Charge:

Explain the chemistry behind ocean acidification. You should include the formation of carbonic acid from carbon dioxide, how this reacts with carbonate ions, and how continued CO2 emission will impact ocean pH.

A recent Chemistry & Engineering News issue, that was also sent out as a Canvas announcement last week, had a not the editor highlighting Lawrence Knox (pictured). Knox and his brother both received a Ph.D. in Chemistry in the 1 (Harvard for Lawrence and MIT for his brother William). In the article, Knox did extensive work in the areas centered around the two structures below. He was able to demonstrate through experimentation what others only were able to theorize. Br A B + a) Today, we should know the reason based on our fundamentals, but Knox observed Molecule A to [Select] only! b) How many pi electrons are present in the aromatic ion (Molecule B)? [Select] Enter a nur

1: Write all the chemical reactions involved in the formation of acid rain from sulfur dioxide (SO2) and rain (H2O).

FALBERTA It is estimated that the total amount of oxygen (O2) contained in BIFS is equivalent to 6.6% of the oxygen present in the modern atmosphere. This is quite impressive given that the atmosphere during Archaean and early Proterozoic times was largely devoid of oxygen! Therefore, this reflects the photosynthetic efficiency of the early biosphere, coupled with its operation over long periods of time. Knowing that the mass of the modern atmosphere is 5.01×1018 kg, of which 21% is oxygen, what is the mass (in kilograms) of oxygen contained within BIFS? 6.9 x 1016 kg of O2 contained in BIF deposits Knowing that the molecular mass of O2 is 32 g/mole (0.032 kg/mole), how many moles of O2 are contained within BIFS? 2.17 x 1018 moles of O2 contained in BIF deposits Now, let us think about iron (Fe). The total mass of BIF's globally is estimated at 5.0x1017 kg, wherein iron accounts for approximately 35% by mass. The atomic mass of iron is 55.8 g/mole (0.0558 kg/mole). What is the total…

Scrubbers are a type of pollution control technology installed on industry smokestacks to capture sulfur dioxide before it is emitted to the atmosphere. Once collected, the sulfur dioxide can be used to manufacture sulfuric acid, which can be sold to other companies that make detergents. Explain how the use of scrubber technology benefits both industry and the environment.

H2X2O3 is a weak acid. What is [X2O32–] in a 0.44 M  H2X2O3 solution?   A. 1.1 x 10–7 M   B. 0.60 M   C. 7.1 x 10–7 M   D. 1.5 x 10–5 M   E. 7.1 x 10–11 M   F. 0.11 M   G. 1.1 x 10–11 M [Ka1 = 1.1 x 10–7;  K a2 = 7.1 x 10–11]

Please help me with this, double check your answers other tutors got it wrong.

Pls do Asap...! Pls do que 1 as soon as possible

Give explanation of the correct option and explanation of the incorrect options. Hand written solutions strictly prohibited.

A. Calculate the concentration of nitrate ion in a solution of 0.10 M Barium nitrate solution following the electroneutrality principle (ENP).

is this correct?

10. The oxides of Group 15 react with water to give acids. Which of the following chemical equation is CORRECT to describe the reaction? A. N2O3 + H20 → HNO3 В. Р.Ов + 6H:0 АН:РОз C. As406 + H20 → HASO3 D. SbĄO6 + H20 → HS6O3

Write out the balanced chemical reaction of oxygen with main group compounds in their elemental forms to form the following acids in a redox process. Include the oxidation states on all elements in the reactions. You may use water or H+ as a reactant or product. This is similar to balancing redox reactions that we learn in gen chem. a. H2SO4 504 b. HNO3 c. H3PO4

20. Complete and balance the equations a. NaHCO3 (s) → 21. How could you simply test for the presence of CO3 in an unknown?

7. Methylhydrazine is commonly used as a liquid rocket fuel. Its combustion is indicated by the following reaction. N₂H3 CH3(1) + O20) → N2(9) + CO2(g) + H₂O (9) a. Balance this equation. b. Calculate AH for this reaction.

2. Based on what you have learned so far, why is it necessary to stir the water and wait until the end of the video to read the dissolved oxygen? The stirring aerates the water, causing the oxygen to dissolve more easily in the water. The stirring causes oxygen molecules to leave. The stirring causes the H20 to break apart and release oxygen. The stirring causes hydrogen gas to mix with oxygen gas making water.
