uranium
palladium
actium
thorium
Correct answer is A

A major source of oxide of nitrogen is from the burning of
coal
wood

Correct answer is C
No explanation has been provided for this answer.
Charles’s law
Boyles’s law
Graham’s law
Avogadro’s law
Correct answer is B
V = 1/P
cross multiply
K = VP
V1P1 = V2V2
For a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship, when temperature is held constant.
The equations supports only Boyle’s law. Option A,C,D are not in support of the equation...

Fehling’s solution
sodium hydrogen trioxocarbonate (iv)
Ammoniacal silver trioxonitrate(V)
Correct answer is C
Sodium hydrogen trionocarbonate iv is the only distinguishing reagent between ethanoic and ethanol. Option A, B, D are not conspicuous in distinguishing between ethanoic and ethanol
