I think it’s Cr3+ because best oxidizing agent means best reduction one (gains electrons). Since Cr3+ has 3 less electrons, I assume that one would gain electrons the easiest.
Answer:
25%
Explanation:
Efficiency is (output work ÷ input work) × 100
so
Efficiency = (300 J ÷ 1200 J ) × 100 %
= 25%
Elements that belong to the same period which is seen horizontally in the periodic table have different properties. Elements with similar properties are seen in columns or groups. Elements in the same period have similar principal quantum number and belong to the same principal shell. Hence the answer is that t<span>hey have different properties that repeat across the next period</span>.
The volume of nitrogen dissolved in blood plasma is 0.4 L.
<h3>What is the maximum volume of nitrogen gas, in liters, that can dissolve in the diver's blood plasma?</h3>
The maximum volume of nitrogen that can dissolve in the diver's blood plasma is obtained as follows:
Number of moles of nitrogen dissolved at a depth of 93.0 m = Henry's constant * pressure at 93.0 m * volume of plasma
Number of moles of nitrogen = 5.80 × 10⁻⁴ * 10 * (4.95 * 55%)
Number of moles of nitrogen = 0.0158 moles
Hence,;
n = 0.0158 moles
R = 0.08206 L.atm/mol/K
T = 37 + 273 = 310 K
P = 1 atm
V = 0.0158 * 0.08206 * 310/1
V = 0.4 L
In conclusion, the volume of nitrogen dissolved in blood plasma is determined using the number of moles of dissolved nitrogen.
