Answer: The net change in the atoms is the conversion of a neutron to a proton, turning Carbon (6 protons) into Nitrogen (7 protons).
Explanation:
Carbon-14, generated from the atmosphere, has 6 protons and 8 neutrons. That's where the 14 comes from, called the mass number, is the sum of protons and neutrons (6+8=14).
Carbon-14 is radioactive and decays by beta decay. That means one of its neutrons spontaneously turns into a proton, an electron, and a neutrino, according to:
After that, the atom has 7 protons and 7 neutrons, maintaining its mass number but changing its atomic number from 6 to 7, turning into Nitrogen.
Answer is: the oxidation number of oxygen must decrease.
Oxidizing agent is element (substance) that gain electrons in chemical reaction.
For example, balanced chemical reaction: C + O₂ → CO₂.
Oxygen change oxidation number from 0 to oxidation number -2 (reduction) and carbon change from 0 to +4 (oxidation)
Answer:
it's the third one
Explanation:
in the first one oxygen molecules aren't balanced
the second ok me oxygen isnt balanced
and the fourth one hydrogen isn't balanced
hope it helps ;)
Newton's Second Law states:
The acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the mass of the object.
since the net force and the acceleration ar directly proportional, as the net force increases the acceleration will increase.
hope this helps :)
2Na + Cl2 ----> 2NaCl
.: product have to be " 2NaCl "
