Watts are units used to measure power. power can be defined as rate of energy transfer
500 watts means - 500 J of energy per second
in 1 second - 500 J of work is done
therefore within 10 seconds - 500 J/s x 10 s = 5000 J
work of 5000 J is carried out in 10 seconds
The correct answer of the given question above would be FINGERPRINTS. Molds might be used for evidence such as fingerprints. This is now a possibility of replicating fingerprints which is called a fingerprint mold. Hope this is the answer you are looking for.
<span>After 1 half-life, 1/2 the sample has decayed. After 2 half-lives 3/4 of the matter has decayed. So after, 3 half-lives about 11/12 would have decayed.</span>
Answer:
See explanation
Explanation:
The periodic table shows the atomic number and mass number of each element.
We know that the atomic number shows;
- The number of protons in the nucleus of the atom
- The number of electrons in the neutral atom of the element.
So we obtain the number of protons and electrons by looking at the atomic number shown in the periodic table.
We also know that;
Mass number = Number of protons + number of neutrons
Since number of protons = atomic number of the atom
Number of neutrons = Mass number - atomic number
Hence we obtain the number of protons by subtracting the atomic number from the mass number given in the periodic table.
Answer: Habers process is the industrial process used for the production of ammonia
Explanation:
Habers process is the industrial process used for the production of ammonia. It uses hydrogen from natural gas and nitrogen mainly from atmosphere under extremely high pressures (150-200atm) and moderately high temperatures 
.
The catalyst used in Habers process is iron.
The balanced chemical reaction is:
