Protons and neutrons are the sub-atomic particles present in the nucleus of an atom where as electrons are present revolving round the nucleus in orbits. Electrons are negatively charged, protons are positively charged where as a neutron is a neutral species. It is the presence of electric charge that lead to the discovery of electrons (negative charge) and protons (positive charge), while it took time to discover neutral as they were electrically neutral species. Neutrons carrying no charge were not detected easily by passing electromagnetic radiations. Therefore, neutrons were the last of the three subatomic particles, to be discovered.
Answer:
The balanced chemical reaction is expressed as:
HCl + NaOH ---> NaCl + H2O
We are given the amount and the concentration of the sodium hydroxide reactant. This will be the starting point for the calculations.
0.100 mol NaOH/L solution (0.06 L solution) ( 1 mol HCl / 1 mol NaOH) = 0.006 mol HCl
Molarity = amount in moles / Volume of solution = 0.006 mol HCl/ 0.150 L
Molarity = 0.04 M
Explanation:
The Correct Answer Is D: Wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
Proof:
The answer is: [C]: Mg<span>₂N₃.

Answer: Many elements produce colors in the flame when heated.
Explanation:
The origin of this phenomenon lies in the arrangement, or “configuration” of the electrons in the atoms of the different elements In the flame test, if this energy has the form of visible light, the flame will produce a color characteristic of the element.
