Answer:
1) 17.5 mL
Explanation:
Hello,
In this case, the reaction between sulfuric acid and potassium hydroxide is:
In such a way, we notice a 1:2 molar ratio between the acid and the base, therefore, at the equivalence point we have:
And in terms of concentrations and volumes:
Thus, we solve for the volume of acid:
Best regards.
Answer:
Thank you for da free points
Explanation:
Thermal energy is heat and if you add heat to ice, it will melt and become a liquid (water)
Answer:
The unknown metal could be calcium or magnesium.
Explanation:
Displacement of a metal from its chemical reaction is shown by the reaction known as single displacement reaction. The reactivity of metal is determined by the reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the reactivity series.
Metal B is more reactive than metal A.
The metal which easily displaced aluminium will lie above in the series but that same element cannot displace sodium, so it will lie below in the series.
Hence, from the series, we conclude that the unknown metal could be calcium or magnesium.
This is correct what do you need help in?
