Answer:
Electric hot plate
Explanation:
Considering that the liquid sample is flammable, it wouldn’t be a good idea to have it near a source of fire which the Bunsen burner provides, rather it would be better to heat through an electric hot plate as its not near a source of flame and instead produces heat through electricity.
2AgNO3+K2CrO4⇒Ag2CrO4(s)+2KNO3
Hence by mixing 0.0024M AgNO3 and 0.004M
K2CrO4, we will have Ag2CrO4 which is precipitated out and leave us with
0.0024M KN03 which is mixed with (0.004-0.0024/2)M, it can be 0.0028M, of K2Cr04
Answer:
hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes, and specific vocabulary has been developed to describe these concentrations in relative terms. A solution is neutral if it contains equal concentrations of hydronium and hydroxide ions; acidic if it contains a greater concentration of hydronium ions than hydroxide ions; and basic if it contains a lesser concentration of hydronium ions than hydroxide ions.
Answer:
Hey dear, foodstuff with acid components should not be stored in aluminum utensils because Aluminum is one of the most reactive metal which can easily react with acid to form toxic substances which can effect our health .
HOPE THIS HELPED!!!!!!XDDD
