Lithium
Li → Li⁺ + e⁻
Li 1s²2s¹ → Li⁺ 1s² + e⁻
Yea it can kill you in many ways.
The answer is 69.048%.
Mass of potassium dichromate (K₂Cr₂O₇) is 294 g, which is a 100%.
Given mass of chromium is 52 g. So, the mass percent of chromium in the compound is 17.687%:
52 g : x% = 294 g : 100%
x = 52 ÷ 294 × 100 %
x = 17.687%
Given mass of potassium is 39 g. <span>So, the mass percent of potassium in the compound is 13.265%:
39 g : x% = 294 g : 100%
x = </span>39 ÷ <span>294 × 100 %
x = 13.265%
Therefore, </span>the mass percent of oxygen in the compound is <span>69.048%:
100% - </span>17.687% - <span>13.265% = 69.048%.</span>
Flood plains are desirable farm land in spite of the fact that they are prone to flooding because of its high fertility.
<h3>Why are floodplains desirable farm land?</h3>
Floodplains are very fertile agricultural areas because the floods carry nutrient-rich silt and sediment and deposited it that plains. Floodplains are flat which make easier farming.
So we can conclude that flood plains are desirable farm land because of its high fertility.
