<span>Electrons, the negatively charged particles that carry electricity in metals, can be ejected from the material if it is bombarded by a large number of high-speed electrons. This effectively, leads to some metallic electrons being "knocked" out of the material. </span>
The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun's gravitational pull, all the planets in our solar system orbit around it.
Answer:
The answer to your question is: x = 0.185 mol of Al2O3
Explanation:
Data
10 g of Al and 19 grams of O2
Reaction: 4Al + 3O2 → 2Al2O3
4(27) 3(32) 2 ( 102)
108g 96g 204g
Limiting reactant
108g Al ------------------ 96g O2
10 g ----------------- x
x = (10 x 96) / 108 = 8.9 g of O2
Then limiting reactant is Al
So
108 g of Al ---------------------- 204 g of Al2O3
10 g ---------------------- x
x = (10 x 204) / 108 = 18.8 g of Al2O3
102 g of Al2O3 ----------------- 1 mol
18.8 ----------------- x
x = 0.185 mol of Al2O3
The relationship is: I₂ < I₃
That's because by removing electron the rest of them is more attracted by positively charged nucleus (there are less of them and the charge of the nucleus is constant) and it's more difficult to remove another one.
<span>The magnetic force is in the positive y direction. This can be found using the "right hand rule" of forces.</span>
