A) would be correct.
The moon is right next to Earth.
Earth orbits around the sun.
Our solar system is at the edge of the Milky Way. So the edge of the Milky Way would be nearer than the center.
The amount of grams that are in 2.3 moles of N = 32.223 or 32/100
Because there are 14.01 grams per mile of nitrogen atoms.
So…
14.01 x 2.3= 32.223
Hope this helps :)
1. 4 electrons
2. Ernest Rutherford
3. Discovered the existence of a center of atom
4. 17 protons
I believe your answer is B.
Answer:
47,9 kJ/g
Explanation:
The enthalpy of combustion is the change in energy due the reaction of combustion of n-octane. If the enthalpy is -4,79x10⁷ J/kg And knowing (1000J = 1kJ) (1000g = 1kg). The enthalpy of combustion expressed in kJ/g is:
= <em>47,9kJ/g</em>
