D. Electronegativity and first ionization energy both increase as you
move up the periodic table.
A solar panel works by talking in light and transforming it into energy and a windmill collects kinetic energy to transform it into energy.
Answer:
12 liters of oxygen are released from the decomposition of the peroxide.
Explanation:
The hydrogen peroxide is decomposed by this reaction:
2 H₂O₂ (l) → 2 H₂O (l) + O₂ (g)
Molar mass H₂O₂ = 34 g/m
Moles of peroxide: 36.5 g / 34 g/m = 1.07 moles
Ratio is 2:1, so 2 moles of peroxide will be decomposed in 1 mol of oxygen (exactly the half)
1.07 moles of peroxide will be decomposed in the half of moles, 0.54 moles
Let's apply the Ideal Gases law Equation to solve the volume
1 atm . V = 0.54 mol . 0.082 .273K
V = (0.54 mol . 0.082 .273K) / 1 atm → 12L
One lithium (Li) atom can combine with one fluorine (F) atom. Together, they make the formula LiF. Fluorine has seven electrons of it's own. Lithium gives up its one electron to make both atoms happy. So the fluorine atom has eight electrons, and a filled outer shell.
