Answer:
percent composition for CO2 is 0.04%
Answer : The correct option is, 12.40
Explanation : Given,
Concentration of ion = 0.025 M
First we have to calculate the pOH.
Now we have to calculate the pH.
Therefore, the pH of a solution is, 12.40
Answer:
D
Explanation:
Because the number of protons is the same as the atomic number, we know what the number of protons has to be 26. The mass number, 55, is the same as the number of protons plus neutrons. Lastly, because there is no charge on this atom, the number of electrons would have to be the same as the number of protons, which is 26.
Answer:
Ionic compounds are crystalline solids, soluble in water and conduct electricity when molten or in solution. These characteristics are due to the type of link that holds them together.
Computer models are generally used to predict long term events
