Answer:
Becquerel was studying the properties of X-Rays when he discovered radioactivity. His original theory was that X- Rays arose from uranium absorbing...
Explanation:
Answer:
18 electrons
Explanation:
Note: The third energy level can actually hold up to 18 electrons, so it is not really filled when it has 8 electrons in it.
Answer:
D. 18.7 grams
Explanation:
The coefficients are the key.
Create a proportion with them, and the molar mass, and then solve for x:
First you find the molar mass of the formula.
3C: 36.03g + 8H:8.08g + N: 14.01g + 5O: 80g + P: 30.97g = 169.09g
Then do the mole ratio (304.3g)x(1mole/169.09g) = 1.800 moles
KOH + H2SO4 —> K(+) + HSO4(-) + H2O
Or a total reaction
2 KOH + H2SO4 —> 2 K(+) + SO4(2-) + 2 H2O
