<span>Consider two solutions: solution X has a pH of 4; solution Y has a pH of 7. From this information, we can reasonably conclude that </span>the concentration of hydrogen ions (H⁺) or hydronium ions (H₃O⁺) in solution X is thousand times as great as the concentration of hydrogen ions or hydronium ions in solution Y.
Solution X: c(H⁺) = 10∧-pH = 10⁻⁴ mol/L = 0,0001 mol/L.
Solution Y: c(H⁺) = 10⁻⁷ mol/L = 0,0000001 mol/L.
0,0001 mol/L / 0,0000001 mol/L = 1000.
Answer:
Yes N3- is correct ion notation. The N element is in the form N2 . Also it is a triple covalent bond and so this correct
Answer is: precipitation requires fewer Ag⁺<span> ions in AgBr than in AgCl.
Chemical reactions:
Ksp(KBr) = 5,3</span>·10⁻¹³.
Ksp(KCl) = 1,8·10⁻¹⁰.
Ksp is <span>solubility product constant. The higher the Ksp value, substance is more soluble. KBr has lower Ksp, so it is easier to form precipitant of KBr than KCl.</span>
Answer:
Global Warming!
Explanation:
Greenhouse gases help keeping the Earth warm for example; Carbon dioxide, methane etc. But recently there has been too much pollution which produced more greenhouse gases like; carbon dioxide...Usually trees and plants would help in keeping the air clean by eliminating carbon dioxide but as we know trees are being cut down. Which increases the amount of CO2 (chemical formula of Carbon dioxide) and they capture more heat. Which causes the temperature to gradually increase in earth and ice caps to melt in Antarctica, and causes the water levels to rise.
