we want you to be updated and informed about the Jamb Questions and answers for Chemistry and here we have made these questions and answers for you. The questions are updated and are sourced from the ongoing Jamb Examination.
moles molecules ounces grams Grade 10Periodic Table and Elements Which statement about nitrogen and phosphorus is not correct? Both are in the same group of the Periodic Table. Both are in the same period of the Periodic Table. Both are non-metals. ...
This is because when 2 moles of N2O5 decompose, 4 moles of NO2 and 1 mole of O2 are formed. This implies that the rate of decomposition of N2O5 is twice the rate of formation of O2 and the rate of formation of NO2 is 4 times the rate of formation of O2. Hence, the rate of ...
molality is an important property of solutions. it is used to express the concentration of a solute in a solution and is primarily determined by the solvent’s mass. molality is also known as the molal concentration at times. it is calculated by dividing the moles of a solute by the ...

For this part,you get one point for correctly calculating the number of moles of acid at the equivalence point and one point for providing the correct molarity. Part (e) is a critical thinking question about a new experiment. Would the student have to use a different indicator to figure out...
How many moles of water are there in this bottle of water? How would you measure pH of a solution if I told you how many hydrogen ions there were in it? The nucleus and electrons are oppositely charged. Why do electrons not crash into the nucleus?
