Antoine Henri Becquerel discovered radioactivity when he was studying
X- rays.
He had been studying phosphorescent uranium ores and hypothesized that they might absorb sunlight and reemit it as X-rays.
His hypothesis was wrong, but his experiments led to the discovery of <em>natural radioactivity</em>.
“Esto quiere decir que en una lata de 330 ml tiene alrededor de 36 gramos de azúcar, mientras que una botella de 1 l tendrá 110 gramos”

In an acid-base titration, the neutralization reaction between the acid and base can be measured with either a color indicator or a pH meter. In this experiment, aphenolphthalein<span> color indicator will be </span>used<span>.
</span>Phenolphthalein<span> is colorless in acidic solutions and pink in basic solutions.
Hope this helped

State the given:
Moles of Sulfur = 5 moles
Molar mass of Sulfur = 32.06g/mol
Look through the formulas:
Moles = Mass/Molar Mass
Rearrange the equation:
Mass = Moles x Molar mass
Plug in your given:
5 moles Sulfur x <u>32.06g</u>
1 mol
<u>= 160.3g of Sulfur</u>
