Hawaii was the first state to ratify ERA, followed by approximately 30 other states.
During the mid-1970s, a conservative women in opposition eroded support for the Equal Rights Amendment and amadment failed to achieve ratification.
Answer:
4.35 * 10^-8 M
Explanation:
Since the concentration of the hydronium ion= 2.3 X 10^-7 M
And we know that;
[H3O^+] [OH^-] = 1 * 10^-14
[H3O^+] = concentration of the hydronium ion
[OH^-] = concentration of the hydroxide ion
So;
[OH^-] =1 * 10^-14/[ H3O^+]
But [H3O^+] = 2.3 X 10^-7 M
[OH^-] = 1 * 10^-14/2.3 X 10^-7
[OH^-] = 4.35 * 10^-8 M
The exact answer is 511.219514
Water boils when the vapor pressure of the water equals the atmospheric pressure that's pressing down on it. Water boils at a lower temperature (more easily) at higher elevations (like on mountains), because:
- Atmospheric pressure is lower at higher elevation
- Easier for vapor pressure to equal this lower atmospheric pressure
Since the water boils at a lower temperature, it takes longer for the pasta to cook.
<span>When electrons are excited they get more energy and jump to higher orbitals. As they loose that energy that had excited them in the beginning, they tend to return to their original orbitals and the color that is given off is when this is occurring. </span>
