An atom of chlorine-35 contains 18 neutrons (17 protons + 18 neutrons = 35particles<span> in the </span>nucleus<span>) while an atom of chlorine-37 contains 20 neutrons (17 protons + 20 neutrons = 37 </span>particles<span> in the </span>nucleus<span>). Adding or removing a neutron from an atom's </span>nucleus<span> creates </span>isotopes<span> of a particular element.</span>
Answer:
Explanation:
Heat involved Q = mcΔt where m is mass , c is specific heat of water and Δt is rise in temperature
= 150 x 4.18 x 25.8 J .
= 16176.6 J .
As the temperature rises , the reaction is exothermic.
The reaction is not possible.
You are destroying O atoms and creating Cl atoms. An chemical reaction cannot convert atoms of one element to those of another element.
Answer : 0.026 moles of oxygen are in the lung
Explanation :
We can solve the given question using ideal gas law.
The equation is given below.

We have been given P = 21.1 kPa
Let us convert pressure from kPa to atm unit.
The conversion factor used here is 1 atm = 101.3 kPa.

V = 3.0 L
T = 295 K
R = 0.0821 L-atm/mol K
Let us rearrange the equation to solve for n.



0.026 moles of oxygen are in the lung
B: SO2
S=Sulfur
O=Oxygen
Dioxide if i am correct means 2 oxygen.
so thats one Sulfur and 2 oxygen.
