Which best describes the oxidizing agent in this reaction? Cl2(aq) + 2Br(aq) --> 2Cl(aq) + Br2(aq)

Answers

Answer 1

Answer:

The reaction is:

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

The oxidizing agent is the one that is being reduced which is chlorine where the charge changed from neutral to -1 while the reducing agent is the one being oxidized which is bromine where the charge change from -1 to a neutral charge.

Answer 2

Answer:

Answer:

The answer is C:

Chlorine (Cl) is the oxidizing agent because it gains an electron

To what volume in millimeters must 50.0 mL of 18.0 M H2SO4 be diluted to obtain 4.35 M H2SO4?

Answers

We know that to relate solutions of with the factors of molarity and volume, we can use the equation: $M_(1) V_(1) = M_(2) V_(2)$

**NOTE: The volume as indicated in this question is defined in L, not mL, so that conversion must be made. However it is 1000 mL = 1 L.

So now we can assign values to these variables. Let us say that the 18 M $H_(2) SO_(4)$ is the left side of the equation. Then we have:

$(18 M)(0.050 L)=(4.35M) V_(2)$

We can then solve for $V_(2)$ :

$V_(2)= ((18M)(0.05L))/(4.35M)$ and $V_(2) =0.21 L$ or $210 mL$

We now know that the total amount of volume of the 4.35 M solution will be 210 mL. This is assuming that the entirety of the 50 mL of 18 M is used and the rest (160 mL) of water is then added.

N2 + 3H2 mc033-1.jpg 2NH3 What is the percent yield of NH3 if the reaction of 26.3 g of H2 produces 79.0 g of NH3?

Answers

The balanced chemical reaction is:

N2 + 3H2 = 2NH3

We are given the amount of H2 being reacted. This will be our starting point.

26.3 g H2 (1 mol H2 / 2.02 g H2) 2 mol O2/3 mol H2) ( 17.04 g NH3 / 1mol NH3) = 147.90 g O2

Percent yield = actual yield / theoretical yield x 100

Percent yield = 79.0 g / 147.90 g x 100

Percent yield = 53.4%

Answer:

53.4 percent yield, the fourth option

Which 1-mole sample has the least entropy?(1) Br2(s) at 266 K (3) Br2(l) at 332 K
(2) Br2(l) at 266 K (4) Br2(g) at 332 K

Answers

The correct answer is option 1. Entropy is the degree of disorderliness in a system. Among the phases, solid has the most ordered structure. Also, at lower temperatures the molecules will have less kinetic energy therefore less motion. Thus, bromine in solid form at 266K has the least entropy.

Explanation:

Air bags, which act as safety devices in cars, contain solid sodium azide. On impact, the sodium azide releasesnitrogen gas, which expands the air bag. The main benefit of using a gas instead of another type is that —
A. gas molecules are subject to ionic bonding
B. the separation of gas molecules is much greater than the volume they occupy
C. gases won’t explode the bag on very hot days
D. gas molecules don’t transfer excess Kinetic Energy

Answers

The answer is; D

The reason for this is because gases are compressible . Much of the energy of the impact created when your head hits the air bad is absorbed by the gas (through compression and rarefaction) hence reducing the damage to the head in case of an accident.
