Answer:the cation can't be drived from an acid
Explanation:
Example
HCL+MgOH2=MgCl2+H2O
The cation in the salt magnesium chloride is magnesium which is derived from the base and the anion chlorine from the acid hydrochloric acid. The same is true in water.
Please can you add as brainleist please!!!!!!!!!!!!!!!!!!!!
D. They're the main site of photosynthesis in autotrophs.
From the calculations, the heat of the reaction is 44.4 kJ/mol.
<h3>What is the enthalpy of reaction?</h3>
The enthalpy of reaction refers to the amount of heat that is absorbed or evolved in a reaction.
Number of moles of NaOH = 1.1 g /40 g/mol = 0.0275 moles
Mass of the water = 22.1 mL or 22.1 g
Given that;
H= mcdT
H = 22.1 g *4.184 * (31.4 - 18.2)
H = 1221 J or 1.221kJ
ΔH rxn = -(1.221kJ)/0.0275 moles
ΔH rxn = 44.4 kJ/mol

Step one write the chemical equation for reaction
= Ag2O + 2(C10H10N4SO2)---> 2 ( AgC10H9N4SO2)
The reacting ratio of Ag2O to AgC10H9N4SO2 is 1:2 from the reaction above
step 2; find the number of moles of AgC10H9N4SO2
that is mass/molar mass
The molar mass of AgC10H9N4SO2 = 107.86 +(12 x10) + (1 x 9) + (4 x 14) +32 +(16 x2) =356.86g/mol
moles is therefore= 25g/356.86g/mol= 0.07moles
by use of mole ratio the moles of Ag2O= 0.0702=0.035moles
mass = moles x molar mass
the molar mass of Ag2O=231.72 g/mol
mass is therefore= 231.72g/mol x 0.035moles= 8.11grams
