Answer: Strong acid vs weak acid
Strong acids and strong bases refer to species that completely dissociate to form ions in solution.
Explanation: By contrast, weak acids and bases ionize only partially, and the ionization reaction is reversible. Thus, weak acid and base solutions contain multiple charged and uncharged species in dynamic equilibrium.
Answer:
1,063 grams H₃PO₄
Explanation:
To find the mass of phosphoric acid (H₃PO₄), you should (1) convert molecules to moles (via Avogadro's number) and then (2) convert moles to grams (via molar mass from periodic table).
Molar Mass (H₃PO₄): 3(1.008 g/mol) + 30.974 g/mol + 4(15.998 g/mol)
Molar Mas (H₃PO₄): 97.99 g/mol
6.534 x 10²⁴ molecules H₃PO₄ 1 mole 97.99 g

Answer:
(a) 
(b) 
Explanation:
The reaction that is carried out by the enzyme catalase produces 
The reaction that is carried out by the enzyme catalase produces
Q = mcΔT
m = 75 g
c = 4.25 J/gram°C
q = 2450 J
q/mc = ΔT
2450/(75 • 4.25) = 7.7°C
The temperature increased by 7.7°C.
