Balance the reaction first:
3KOH + H3PO4 —> K3PO4 + 3H2O
So for every mol of H3PO4, you need 3 mol of OH- to fully neutralize the acid, since H3PO4 is polyprotic.
0.0200 L KOH • (2.000 mol KOH / L KOH) • (1 mol H3PO4 / 3 mol KOH) = 0.0133 mol H3PO4
Divide this by the volume of H3PO4 to get the concentration.
0.0133 mol H3PO4 / 0.0250 L = 0.532 M H3PO4
Effective Nuclear charge is represented by a Z * and sometimes Zeff. It's the net positive charge of an electron in a polyelectronic atom (valence electrons) the equation for it is Z*=Z-S
Z is the atomic number and S is the Shielding electrons
Answer:
the answer is A ( The basement)
HOPE THAT HELPSSS!!!
Answer:
But because the Earth rotates, circulating air is deflected. Instead of circulating in a straight pattern, the air deflects toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere, resulting in curved paths. This deflection is called the Coriolis effect.
The Coriolis effect describes how Earth's rotation steers winds and surface ocean currents. ... The Coriolis effect causes the path of a freely moving object to appear to curve. This is because Earth is rotating beneath the object. So even though the object's path is straight, it appears to curve.
Explanation:
That power is electricity. And we use that in our daily life! Without nuclear power plants producing elextricity to power your computer, you would not have been able to ask this question on Brainly :) :P
