The specific heat of water is 4.18 j/(g⋅∘c). calculate the molar heat capacity of water. express your answer to three significan
iogann1982 [59]
Specific heat capacity of any substance comes with the unit : J/(g*degree C)
for molar capacity , change gram -> moles  unit ( J / moles * degree C)

4.18 J  / mol - degree C

H = 1.01 g * 2 =   2.02 g
O = 16 g

2.02 + 16  =  18.02  g

Now  :-    4.18  J / mol- degree C) *  18.02 /  1 mole H2O
molar heat  =  75.3 J / mol - degree C

Which of the following is a salt that will form from the combination of a strong base with a weak acid?
zaharov [31]

Answer:

A. NaHCO₃

Explanation:

NaHCO₃ ⇒ NaOH + H₂CO₃

NaOH is a strong base and H₂CO₃ is a weak acid. Therefore, NaHCO₃ is a salt of a strong base-weak acid reaction. The salt is basic because carbonic acid (H₂CO₃) is a weak acid so it remains undissociated. So, there is a presence of additional OH⁻ ions that makes the solution basic.

Hope that helps.
