The most mass is in my grandmas, because she a big lady. Respectfully.
Answer:
It traveled for 4 seconds at a distance of about 4.1 meters. With a velocity of 10%.
Explanation:
Each isotope of Oxygen has a different number of neutrons
<h3>Further explanation
</h3>
The elements in nature have several types of isotopes
Atomic mass is the average atomic mass of all its isotopes
Isotopes are atoms has the same number of protons but has a different number of neutrons.
So Isotopes are elements that have the same Atomic Number (Proton)
Some of the isotopes of oxygen are:
Each isotope has 8 protons and 8 electrons but has a different number of neutrons
For O-16: number of neutrons = 16-8 = 8
For O-17: number of neutrons = 17-8 = 9
For O-18: number of neutrons = 18-8 = 10
Answer:
The combustion will release -3,321 KJ/mol of energy
Explanation:
What we need to do here is to first calculate the number of moles of methane burnt.
Mathematically, the number of moles of methane burnt = mass of methane/molar mass of methane
Molar mass of methane = 16g /mol
Thus the
number of moles will be ;
59.7/16 = 3.73 moles
Now, 1 mole of methane produces -890 KJ/mol if energy
Then the energy produced by by 3.73 moles of methane would be 3.73 * 890 = -3,320.8125
which is approximately -3,321 KJ/mol
Kindly note that the amount of heat is negative because it is an exothermic reaction
