The balanced equation for the acid base reaction is as follows
NaOH + HCl ---> NaCl + H₂O
stoichiometry of NaOH to HCl is 1:1
the number of NaOH moles reacted - 0.200 mol/L x 0.0250 L = 0.005 mol
according to molar ratio
number of NaOH moles reacted = number of HCl moles reacted
therefore number of HCl moles - 0.005 mol
volume of 30.0 mL contains 0.005 mol
therefore 1000 mL contains - 0.005 mol / 0.030 L = 0.167 M
concentration of HCl is 0.167 M
B) as a base is no longer neutral or acidic, so it is an error
Answer:
14.2 L H2S
Explanation:
Mole ratio
2 mol H2S:2 mol SO2
We are just looking for volume, so the required amount is the same as the produced amount as long as the mole ratio is balanced.
The amount of heat a 30-gram sample of substance Y absorbs to melt at its melting point is <u> 105 J.</u>
The enthalpy of fusion of a substance additionally referred to as heat of fusion is the alternate in its enthalpy resulting from imparting electricity, usually heat, to a specific amount of the substance to change its state from a stable to a liquid, at a steady strain.
The heat of fusion is the amount of heat vital to alternate 1 g of a stable to a liquid without a temperature exchange.
The heat of fusion is the strength wished for one gram of a solid to melt without any change in temperature. The heat of vaporization is the energy needed for one gram of a liquid to vaporize (boil) without a trade-in strain.
q = m·ΔHf
= 30 × 3.5
heat <u>= 105 J</u>
