Answer:
In a parallel circuit, current divides through resistors and current might be different depending upon the resistor and all resistors have the same potential difference. Therefore, if a parallel resistor was removed then the total resistance of the circuit will increase.
<span>When electrons are excited they get more energy and jump to higher orbitals. As they loose that energy that had excited them in the beginning, they tend to return to their original orbitals and the color that is given off is when this is occurring. </span>
In regards to the given question, option “1” is the correct
option. When propane is burnt to complete combustion, it results in the
formation of two completely different substances. It actually forms a mixture
of water vapour and carbon dioxide. When NaCl or sodium chloride is melted, it
does not result in the formation of any new substance and so option “2” cannot
be the correct answer. With regards to deposition of carbon dioxide and solidification
of water, no new substance gets formed and so can be neglected as the answer to
the question.
Sn2+
Your protons equal the atomic number of an element: Sn (Tin).
The amount of protons and electrons will be the same if the atom is neutral. In this case, tin has lost two electrons and so tin is no longer neutral and becomes Sn2+
To double check, you would subtract the atomic number from the mass number of tin to see if the number of neutrons is equal to what has been provided.
mass number - atomic number = number of neutrons
118 - 50 = 68
