Answer:
The isotope with the greatest number of protons is:
- <u>option D: Pu-239, with 94 protons</u>
Explanation:
The number of <em>protons</em> is the atomic number and is a unique number for each type of element.
You can tell the number of protons searching the element in a periodic table and reading its atomic number.
Thus, this is how you tell the number of protons or each isotope
Sample Chemical symbol Element atomic number # of protons
A Pa-238 Pa protactinium 91 91
B U-240 U uranium 92 92
C Np-238 Np neptunium 93 93
D Pu-239 Pu plutonium 94 94
Answer:
So combining blue with yellow light is like combining blue light with red and green light. The result of combining these three primary colors of light is to produce white light.
Explanation:
The equation that correctly represent the reaction for formation of ammonia is
N2+ 3H2 → 2NH3 (answer D)
1 mole of nitrogen gas (N2) react with 3 moles of hydrogen gas (H2) to form 2 moles of ammonia ( NH3). This is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. The process is exothermic hence energy is released.
The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near itshydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.
There is 100 centimeters in 1 meter
Divide 15.6 with 100
15.6/100 = 0.156
0.156 meters is your answer
hope this helps
