What is the pH of a solution that is prepared by adding 38.34 mL of 1.83 M HCl to 0.772 L of 0.315 M trimethylamine (a weak base)?

What is the reason for the arrangement of

F-,N3-,O2-,Na+ in the order of increasing size

Arrange the ions N3-,F-,O2- and Na+ in the order of increasing size

Lead metal is obtained from lead sulphide through the following reaction:

          2PbS(s) + 2C(s) + 3O₂(g) → 2Pb(s) +2CO(g) + 2SO₂(g)

Suppose 100 g of PbS is reacted with 4g of C and 20g O₂.

Find the limiting reactant for this reaction

Decribe how scientist would proceed from the formulation of a question to the establishment of theory .

Read about structure of atom as well as periodic table, keep in mind reactivity; isotope, Bohr model of atom and Aufbau process, compared the oxidation number and formal charges of hydrogen in molecules; H2, BeH2 and H2O

In the reaction, 150. g of ammonia (NH₃) were reacted with 150. g of oxygen (O₂) to produce nitrogen monoxide (NO).

How much nitrogen monoxide would be produced? 

B. If the expressed mass of AICI3, to be formed is 3.5 g, what should be the initial mass of the pure aluminum metal?

C. If the actual mass of AlCl3 produced is 3.1 g, what is the percentage yield of the reaction?
