Answer: A. National Organ Transplant Act of 1984

Explanation: The National Organ Transplant Act of 1984 established the Organ Procurement and Transplant Network (OPTN), a national system to address fair allocation of organs for transplant. Patients on the waiting list are in end-stage organ failure and have been evaluated by a transplant physician at U.S. hospitals where organ transplants are performed.

The OPTN is operated by the nonprofit United Network for Organ Sharing (UNOS). UNOS committees and a board of directors composed of transplant physicians, government officials, immunology specialists, organ donation experts, donor families, transplant recipients, and members of the public have created rules for organ allocation.

Scott is making a chart to show the difference between chemical reactions and nuclear reactions. Which part of his chart is inco

Nimfa-mama [501]

Answer:

The incorrect part of the chart is;

Line 1

Chemical ${}$ Reaction ${}$ Nuclear Reaction

Line 1 Happens in the nucleus of atoms ${}$ Happens between atoms

Explanation:

The given chart can be presented as follows;

Chemical Reaction ${}$ Nuclear Reaction

1. Happens in the nucleus of atoms ${}$ Happens Between atoms

2. Forms new compounds ${}$ Forms new atoms

3. Involves small amounts of energy ${}$ Involves large amounts of energy

From the above chart, line 1 is incorrect because a chemical reaction happens between the valence electrons of the reacting atoms while a nuclear reaction is the reaction that takes place between the nucleus of two or more atoms or the nucleus of an atom and a subatomic particle to produce one or more than new nuclide of a new atom with a change in the mass of the nucleus being represented by the large amount of energy in the reaction. Therefore, a nuclear reaction takes place in the nucleus of an atom, forms new atoms and involves large amounts of energy

The correct arrangement is presented as follows;

Chemical Reaction ${}$ Nuclear Reaction

1. Happens Between atoms ${}$ Happens in the nucleus of atoms

ICE Princess25 [194]

Answer:

Option b. it has the same position and the same acceleration as A

Explanation:

Let's analyze every statement:

a. it has the same position and the same velocity as A

In the instant where B passes A, they Do have the same position. Velocity however, cannot be the same because if they were, ball B would never pass ball A. So, this is false.

b. it has the same position and the same acceleration as A

As we said in the previous option, the position is the same. The acceleration is gravity for both balls, so this is true.

c. it has the same velocity and the same acceleration as A

Acceleration is the same but velocities are not, so this is false.

d. it has the same displacement and the same velocity as A

The distance they have traveled is the same, so the displacement is the same, but the velocity is not, so this is false.

e. it has the same position, displacement and velocity as A

The position and displacement is the same but not velocity, so this is false.

Only option b is true.

Se ha quemado magnesio (reacción con el oxígeno) y se obtuvieron 12g de óxido de magnesio (II). ¿Cuánto magnesio se quemó? ¿Qué

Sedaia [141]

Answer:

The first answer is 7,24g Mg

The second answer is 3,36L O2

Explanation:

Atomic masses: Mg= 24,3 ; O=16

Solution: MMgO = 40,3 g/mol

2 Mg + O2 => 2 MgO

1) 12 g MgO x (2x24,3 g Mg / 2x 40,3 MgO) = 7,24 g Mg

At first calculate moles from Oxygen:

12 g MgO x ( 1 mol from Oxygen/ 2 x 40,3 g MgO ) = 0,15 moles from Oxygen

then ....

0,15 moles from Oxygen x (22,4 lts / 1 mol from Oxygen ) = 3,36 lts

22.4 liters is the constant that we use in this equation, it is a value that is repeated since we are in the presence of a gas with ideal behavior, so it is considered that the normal molar volume of ideal gaseous substances is always 22.4 liters, estimated with a temperature of 0º C and a pressure of 1 atmosphere. (constant temperature and pressure)
