I think it is e sorry if I’m wrong
Answer:
Electrons are in "orbitals", regions of space where there is high probability of being found.
Explanation:
The Wave mechanical model of the atom does not restrict the electrons to certain energy levels only as in the Bohr's model, instead it describes a region around the nucleus called an orbital, where there is a high probability of finding an electron with a certain amount of energy.
Each energy level is composed of one or more orbitals and the distribution of electrons around the nucleus is determined by the number and kind of energy levels that are occupied.
1) Acidic solution. An acidic solution has a high concentration of H+ ions.
2) Basic solution. A basic solution has a high concentration of OH- ions.
3) HCl chemical reaction.
You can also write it as follows
4) pH scale.
When the concentration of H+ is high, the solution is acidic. H+ lowers the pH of the solution.
Option D.
Answer:
13.3 atm(assuming the temperature given is in Celsius)
Explanation:
First, the moles of each gas must be found. .25 mol He, .50 mol CO, .33 mol NO. Next, each set of mols must be plugged into the ideal gas law, PV=nRT, for each gas. Move it around so you get the pressure P=nRT/V. When you calculate everything, you should get 3.08atm He, 6.15atm CO, and 4.06atm NO. Add these together and you get the pressure of the container.
