Answer:
behavior of objects for which all existing forces are not balanced.
Explanation:
The answer to your proposed question is Neutron. This is because the atomic mass unit of a neutron is 1 and so it would contribute to the overall mass of the atom.
I hope this answer helped you!
Answer:
The value is 
Explanation:
From the question we are told that
mass of carbon dioxide produced by one gallon of gasoline is 
The number of cars is 
The distance covered by each car is 
The rate is 
Generally the amount of gasoline used by one car is mathematically represented as
=> 
=> 
Generally the amount of gasoline used by N cars is
=> 
=> 
Generally the annual production of carbon dioxide is mathematically represented as
=> 
=>
that is false it shows you the atoms but the arrangement would have to be a Lewis dot diagram
Answer:isotopes of an element has same number of proton but different number of neutron.
Explanation:
Isotope: The atoms of element having same atomic number but different mass number are called isotope.
Hydrogen has three isotopes called as
1.protium
2.duetrium
3.tritium
All of the isotopes of hydrogen have same atomic number but different masses 1,2,3 respectively.
Isotopes have same outermost shells there for having same chemical properties.
Isotopes have different nuclie due which they have different physical properties.
Tritium the 3rd isotop having diffrent prton to neutron ration emitts radiation there it in traces.
