The electrical charge of an atom having 15 proton, 14 neutrons and 16 electrons is -1. The correct option is D.
What is an atom?
An atom is the smallest unit of any matter which comprises of central nucleus and electrons revolving around the nucleus in definite energy shells. The atom is made up of protons, neutrons and electrons.
The electrical charge of an atom can be calculated as,
Charge of an atom = number of protons - number of electrons
Charge = 15 - 16 = -1.
The neutrons are neutral and do not contribute to the charge, the protons are positively charged and electrons are negatively charged in an atom.
Therefore, the charge of an atom with 15 protons, 14 neutrons and 16 electrons is -1. The correct answer is option D.
converts to in the first reaction. The coefficient in front of is three times the coefficient in front of . In other words, each mole of will produce three moles of . 0.0020 moles of will convert to 0.0060 moles of .
How many moles of thiosulfate ions are required?
reacts with in the second reaction. The coefficient in front of is twice the coefficient in front of . How many moles of does each mole of consume? Two. 0.0060 moles of will be produced. As a result, moles of will be needed.
