The partial pressure of nitrogen gas is calculated to be 21.16 MPa.
The partial pressure of oxygen equates to 5.62 MPa, and the overall gas pressure is stated as 26.78 MPa.
This adheres to the principle that the total pressure in a gas system equals the sum of all individual gas partial pressures.
Thus, the total pressure in the system reflects the sum of the partial pressures of nitrogen and oxygen.
Accordingly, the partial pressure for nitrogen can be derived as follows: Total pressure minus the partial pressure of oxygen.
Thus resulting in: 26.78 - 5.62, which gives a partial pressure of nitrogen at 21.16 MPa.
Answer:
The right responses are "bulb or pump; meniscus; outside".
Explanation:
Pipets are essential tools in laboratory settings. They are designed for transferring liquids from one vessel to another. First, a bulb or pump is attached to the top to empty the pipet completely. Next, fill the pipet until the meniscus (the curved top of the liquid) aligns with the measurement line corresponding to the volume needed. Finally, dispense the liquid into a second container and make sure to eliminate the last drop beyond the pipet tip.
H2PO4- acts as a proton donor, whereas HPO42- serves as a proton acceptor. Step 1: Determining hydrogen ion donors and acceptors in the reaction displayed: H2PO4- is predisposed to release a H+ ion to yield HPO42-. On the other hand, HPO42- is inclined to accept a H+ ion, producing H2PO4-. The process of an acid in a water solvent is characterized as dissociation: HA ⇔ H+ + A- where HA denotes a proton acid. Therefore, H2PO4- = HA and HPO42- = A-. Acids are recognized as proton donors, which is why H2PO4- donates protons and HPO42- accepts them.

Answer: The net ionic equation is 
Explanation:
A double displacement reaction involves the exchange of ions. Chemicals that dissolve in water are marked with the symbol (aq), while those that do not dissolve and remain solid are shown with (s) after their formulas.
The ion-based representation of the equation is:
"Spectator ions" are the ions that do not participate in the chemical reaction, appearing on both sides of the equation in ionic form.
Ammonium and chlorate ions are present on both sides; thus, they do not factor into the net ionic equation.
Therefore, the net ionic equation is:
