Answer:
This isotope has 59 electrons giving it a charge of -2.
Explanation:
To find this we have to understand isotope relates to the mass of the nucleus. This isotope has 59 electrons to counter the protons and give it a negative charge.
Answer:
Explanation:
Given:
Depth = h
Width = w
Length = 1
Now,
Let ρ be the density of water
Thus,
Pressure force at the bottom will be
= Pressure × Area
= ρgh × (w × 1)
also,
Pressure force at the sides will be = 
ρgh × (h × w)
Therefore,
The ratio of the pressure force at the bottom to the pressure force on the side of the tank will be
= 
=
The reported number of moles will be too low since the additional amount of oxygen is not included. It may be 6 drops but the molarity of the solution is 6M. this meas that for every ml of the JNO3 solution there is 6 moles of JNO3. In every mole of <span>JNO3 there are 3 moles of oxygen. So in every drop of oxygen there are 18 moles of oxygen. </span>
Answer:
The answer to your question is Protons = 36, Neutrons = 26, Electrons = 36
Explanation:
⁷⁰Se²⁻
The number of protons is equal to the atomic number, Selenium has an atomic number of 34. Then the number of protons = 34.
The number of neutrons = Mass number - number of protons
= 70 - 34
= 36
The number of electrons = number of protons + 2 because of the 2- next to the symbol of Selenium.
Number of electrons = 34 + 2
= 36
