Which of the following is NOT a type of carbohydrate molecule? Choose one: A. A disaccharide B. A glucose molecule C. A triglyceride D. A polysaccharide

Answers

Answer 1

Answer:

Answer:

The correct answer is C: A triglyceride

Explanation:

A carbohydrate is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms. A carbohydrate is is a synonym of saccharide.

A triglyceride is an ester derived from glycerol and three fatty acids. So not a saccharide. The other 3 options all are saccharides. Triglycerides are the main constituents of body fat.

Answer 2

Answer:

Final answer:

Triglyceride is not a type of carbohydrate molecule. It's a type of fat found in the blood, while disaccharides, glucose molecules and polysaccharides represent different types of carbohydrates.

Explanation:

Among the choices A. A disaccharide, B. A glucose molecule, C. A triglyceride, and D. A polysaccharide, option C. A triglyceride is NOT a type of carbohydrate molecule. Instead, triglycerides are a type of fat found in the blood. A person's body converts calories it doesn't need for energy into triglycerides. On the other hand, disaccharides, glucose molecules and polysaccharides are all different types of carbohydrates, which are molecules consisting of carbon, hydrogen, and oxygen atoms.

Answers

Among all the choices letter A is not an example of electric forces which is a neutron pushing on another neutron. Neutron do not have charge and a mass slightly larger than the proton. I hope my answer helps you.

All of the following are examples of electric force except A. A Neuton pushing on another Neutron. Neutrons are subatomic particles that possess no electrical charge.

Which radioisotope has an atom that emits a particle with a mass number of 0 and a charge of +1?(1) 3H (3) 19Ne
(2) 16N (4) 239Pu

Answers

The radioactive isotope of the element with unstable energy in the nucleus is called a radioisotope. Neon with atomic mass 19 particlehas charge +1 and mass 0.

What are the radioactive particles?

When a radioactive element undergoes decay they emit some types of particles like alpha, beta, or positron particles. The alpha particle has a +2 charge and a mass number of 4.

The beta particle has a -1 charge and a mass number of 0, while the positron has a particle charge of +1 and a mass number of 0.

In the decay of the Neon element, the positron is emitted can be shown as:

$\rm ^(19)_(10)Ne \rightarrow ^(19)_(9)F + ^(0)_(+1)\beta$

Therefore, option 3. $\rm ^(19)Ne$ atom emits positron particle.

Answer: The correct answer is option 3.

Explanation: There are three types of particles that are emitted when a radioisotope undergo decay process:

1. Alpha particle: This particle is emitted when a radioisotope undergoes alpha decay process. The charge on the particle is +2 and mass number is 4.

$_Z^A\textrm{X}\rightarrow _(Z-2)^(A-4)\textrm{Y}+_2^4\alpha$

2. Beta-particle: This particle is emitted when a radioisotope undergoes beta-minus decay process. The charge on the particle is -1 and mass number is 0.

$_Z^A\textrm{X}\rightarrow _(Z+1)^(A)\textrm{Y}+_(-1)^0\beta$

3. Positron particle: This particle is emitted when a radioisotope undergoes beta-plus decay process. The charge on the particle is +1 and mass number is 0.

$_Z^A\textrm{X}\rightarrow _(Z-1)^(A)\textrm{Y}+_(+1)^0\beta$

For the given options undergoing decay processes:

Option 1:

$_1^3\textrm{H}\rightarrow _(2)^(3)\textrm{He}+_(-1)^0\beta$

It emits beta-particle.

Option 2:

$_7^(16)\textrm{N}\rightarrow _(8)^(16)\textrm{O}+_(-1)^0\beta$

It emits beta-particle.

Option 3:

$_(10)^(19)\textrm{Ne}\rightarrow _(9)^(19)\textrm{F}+_(+1)^0\beta$

It emits positron-particle.

Option 4:

$_(94)^(239)\textrm{Pu}\rightarrow _(92)^(235)\textrm{U}+_2^4\alpha$

It emits alpha particle.

Hence, the correct option is Option 3.
