Answer:
6. this is because atomic mass 11 - atomic number 5 is equal to 6 neutrons.
Concentrated sulfuric acid can perform a dehydration reaction with table sugar. After mixing, the color changes from white to brownish and eventually to black. ... As the acid dehydrates the sucrose, the water produced will dilute the sulfuric acid, giving out energy in the form of heat.
Answer:
0.0626 M
Explanation:
Equation of the reaction
CH3COOH(aq) + NaOH(aq) ---------> CH3COONa(aq) + H2O
Concentration of acid CA= ???
Concentration of base CB= 0.1943 M
Volume of acid VA= 10.0ml
Volume of base VB= 32.22 ml
Number of moles of acid NA= 1
Number of moles of base NB= 1
From
CA= CB VB NA/VA NB
Hence ;
CA= 0.1943 M × 32.22 ml × 1/10.0ml ×1
CA= 0.0626 M
The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. ... This chemical series contains helium, neon, argon, krypton, xenon, and radon.
