<u>Gamma Decay</u> in the nucleus is similar to <u>Photon Decay </u>in atoms. When a electron charges energy levels in the atoms, it desposes of photon (with energy of order electron volts).
Answer: Cytosine, Thymine, Cytosine, Guanine (option A)
Explanation:
In DNA strands, you must use base-pairing rules to complete strands.
The base-pairing rules are:
Adenine (A) bonds with Thymine (T)
Guanine (G) bonds with Cytosine (C)
By using these rules, you can pair the sequence GAGC with CTCG
The sequence CTCG is also represented as the bases Cytosine, Thymine, Cytosine, and Guanine, making A the correct answer.
I hope this helps!
Answer:
See to them if they are balanced, i.e., the no. of atoms of each element should be equal on both the sides. If they are so, then its adhered to law of conservation of matter.
A maximum of 8 electrons can share the quantum number n = 2.
Principal Quantum number has a symbol of "n". It tells you the energy level on which an electron resides. Y<span>ou need to determine exactly how many </span>orbitals<span> you have in this energy level before you can determine the number of electrons that can share the value of n.
</span>
The number of orbitals you get per energy level can be found using this formula:
<span>no. of orbitals=<span>n</span></span><span>²</span>
Each orbital can hold a maximum of two electrons, the formula would be:
<span>no. of electrons=2<span>n</span></span><span>²</span>
Using the given formulas:
<span>no. of orbitals = <span>n</span></span><span>² </span><span>= </span><span>2</span><span>² </span><span>= </span><span>4</span>
<span>no. of electrons </span><span>=</span><span>2 *</span><span> </span><span>4 </span><span>= </span><span>8 </span>
Chemical reactions release or absorb heat or other energy or may produce a gas, odor, color change, or sound. If you don’t see any of these indications, a physical change likely occurred. Be aware a physical change may produce a dramatic change in the appearance of a substance. This doesn’t mean a chemical change occurred. Examples of a chemical change would be rusting iron, or burning wood, or even cooking. Examples of physical changes would be tearing paper, boiling water, or freezing popsicles.
