The answer should be A. It takes a very small amount of mass to produce a lot of energy which is displayed in Einstein's equation E=mc². E is the amount of energy given off when some mass is converted into energy.
E=the energy given off, m=the mass turned to energy (I think this is sometimes referred to as the mass defect), and c=the speed of light. Nuclear reactions do not fallow the law of conservation of mass since some of the mass is converted into energy.
I hope this helps. Let me know if anything is unclear.
B because if more soot comes then the darker they will get.
Compounding Corner on RxNet is the best reference for more information regarding compounding
<u>Explanation:</u>
RxNet is an open online community, consolidating scientists from the domains of chemistry, biochemistry and expanding industry of drug innovation and improvement. Compounding presents an innovative way for pharmacists to customize prescriptions to suit the requirements of their patients.
The art of compounding employs advanced medicine while still sticking to the roots of the profession of pharmacy. Compounding pharmacies can create unparalleled dosage forms based on patient preferences. Compounded medicines are usually reliable and sufficient for most victims who have spoken to their physician about their wellness.
Answer: The correct option is, 2.
Explanation:
Nuclear fission: It is defined as the reactions in which a larger unstable nuclei breaks into two or more smaller stable nuclei.
Nuclear fusion: It is defined as the reaction where two smaller nuclei combine together to form a larger nuclei.
Option 1 & option 2 shows fusion reaction and option 3 & option 4 shows fission reaction.
In option 1, helium itself is forming but in option 2, element is heavier than forming which is, neon.
Hence, the correct option is 2.
<h3><u>Answer and explanation</u>;</h3>
- To balance the charges of ions the number of electrons lost is equal to the number of electrons gained. The overall net charge must be zero.
- The number of ions needed to accomplish this is represented by the subscripts.
- For any given ionic compound, the product of the charge on the ion (or multiatomic ionic group) times the subscript of the ion will give a total charge of zero when all ions are considered.
For examples: NaCl Na = +1 Cl = -1 total is zero
