The answer is C. There needs to be equal numbers of protons and electrons. If there are more or less electrons then the atom is no longer neutral!
The number of electrons will equal the number of protons In a neutral atom and the number of protons is the atomic number.
There is a time delay of almost two to three minutes before the reaction proceeds because of the following processes:
<span>1) </span><span> The acid starts to go yellow as the dehydration begins.</span>
<span>2) </span><span> The rate of dehydration then accelerates as the acid heats up because the reaction is exothermic/chemical (releases energy by light or heat). As the sugar molecules are stripped of water, the heat generated turns the water into steam which then expands the remaining carbon into a porous, smoking, black column.</span>
<span>3) </span>This expands out of the reaction vessel, producing a choking acrid vapor and the smell of burned sugar.
<span> At this stage, sulfuric acid is highly corrosive and will burn skin so one must avoid contact with it. </span>
V=2.90 L
c=1.8 mol/L
n(NaOH)=vc
n(NaOH)=2.90L*1.8mol/L=5.22 mol
The charge of the ion would be +2, because there are 2 more protons than there are electrons. The neutrons don't matter because they have a neutral charge, meaning they are neither positive nor negative.
