It is both. We normally think of it as a base because it raises the pH of water by accepting a proton,
HCO3- + H2O <-----> H2CO3 + OH-
but if you add bicarbonate to a strongly basic solution, it actually lowers the pH by donating a proton.
HCO3- + OH- <------> CO3(2-) + H2O. That's why it is an amphoteric substance
<span>The answer is an equation. The equation should be balanced meaning mass on both sides of the equation, that is, products and reactants should have the same mass. This is a requirement due to the law of conservation of mass.The reactants and products are symbolized using <span>formulas.</span></span>
Nitrous oxide .
The Lewis dot structure is attached
Answer:
0.09425
Explanation:
The reactant is in solid phase and therefore has zero partial pressure.
The products have the same mole ratio (1:1) and will have the same partial pressure = 1/2 × 0.614 atm = 0.307 atm
Kp = (NH3)(H2S) = 0.09425
The one element that is less reactive than the others is Selenium.
