OXIDATION IN
Cl2(aq) + 2Brmc003-1.jpg(aq) mc003-2.jpg 2Clmc003-3.jpg(aq) + Br2(aq)

Answers

Answer 1
Answer:

I think the chemical reaction is:

Cl2(aq) + 2Br-(aq) = 2Cl-(aq) + Br2(aq)

The oxidation in this reaction is the reaction for bromine where the charge goes from -1 to a neutral charge while the reduction reaction is showed by the chlorine from a neutral charge to a -1 charge.

Which of the following is true of coral?a.
It is located in deep sea regions.
b.
It supports few species.
c.
It is a large and complex organism.
d.
It is composed of thousands of individuals.

Answers

Coral is found close to shorelines and it can house many different types of organisms. The structures formed by colonies of coral are called reefs, the best example being the Great Barrier Reef in Australia. Coral is actually composed of the skeletons of dead coral. The coral excrete calcium carbonate, resulting in a hard structure which other organisms occupy. The answer is D.

I know for a fact that the answer to this question is d; i just took the test & got it right. It's also the most logical response. Hope i helped!

A balloon is a sphere with a radius of 5.0 m. The force of air against the walls of the balloon is 45 N. What is the air pressure inside the balloon? (surface area = 12.56 x radius^2; 1 Pa = 1 N/m^2)A. 1.4 x 10^3 Pa

B. 3.6 x 10^2 Pa

C. 1.4 x 10^-1 Pa

D. 3.6 x 10^-2 Pa

***Idk how to solve this... pls explain?? thx :)

Answers

Pressure is the force exerted on an object per unit area. The equation is expressed as:

P = F / A

From the given above, we substitute the values to the equation.

P = F/A
P= F / (12.56r²)
P = 45 N / (12.56 x 5²
P = 0.143 N/m²

Therefore, the correct answer is option C, 1.4 x 10^-1 Pa.

If 12.6 grams of iron (III) oxide react with 9.65 grams of carbon monoxide to produce 7.23 g of pure iron, what are the theoretical yield and percent yield of this reaction? Be sure to show the work that you did to solve this problem. unbalanced equation: Fe2O3 + CO yields Fe + CO2

Answers

Theoretical yield of Fe = 8.736gm. Percent yield of Fe = 82.76 %. Hope you are able to see solution :)
