In phytochemial screening, steroid should present in groundnut. However, after doing the experiment, steroid failed to present in groundnut? why? Is there something wrong with the experiment carried out?

Would it be possible to increase the kinetic energy of the particles within a reaction by ionising the constituent molecules and using magnetism to assert an acceleration on them. Could you use this as an alternative to heat?

What volume of 0.117 M HCl is needed to neutralize 28.67 mL of 0.137 M Ca(OH)2 ?

Arsenic in 7,150 g of a herbicide is converted in arsenate ions (AsO4{3-}) and the arsenate ions form a precipitate of Ag3AsO4 with 25,00 ml of AgNO3 solution 0,05000 M. The excess of Ag{+} is titrated with 3,85 ml of a KSCN solution 0,0500 M. Calculate the % concentration of arsenic in the sample.

How to write thermochemical equations for reactions

1)Calculate the grams of EDTA (MW=372,24) required to make a 250,0 ml EDTA solution so that in the titration of 12,50 ml of H2O with 40 french degrees of hardness, 25,00 ml of the edta solution are consumed
2)Calculate the molarity and titer in mg CaCO3/ml of the initial edta solution.
