What is the molecular equation for the reaction of solid calcium carbonate with aqueous acetic acid.
malfutka [58]

Answer:

The molecular equation for the reaction of CaCO₃ with CH₃COOH is:

CaCO₃ (s) + 2CH₃COOH (aq) → Ca(CH₃COO)₂ (aq) + H₂O (l) + CO₂ (g)

Option 1

Explanation:

CaCO₃ + 2CH₃COOH → Ca(CH₃COO)₂ + H₂O + CO₂

Option 3 is the same equation as option 1, but calcium acetate, does not precipitate, so the formed salt, is not a solid.

Option 2 and 4 are wrong because calcium acetate molecular formula is

Ca(CH₃COO)₂

Ca(CH₃COO)₂  → Ca²⁺  +   2 CH₃COO⁻

Air contains nitrogen, oxygen, argon, and trace gases. if the partial pressure of nitrogen is 587 mmhg, oxygen is 158 mmhg, argo
ivanzaharov [21]
According to Dalton's Law of Partial pressure, the pressure exerted by a mixture of non-reacting gases is equal to the sum of their partial pressure.

Mathematically,

                                 Total Pressure = P₍₁₎ + P₍₂₎ + P₍₃₎ + .......    ------(1)
Data given:

                Partial pressure of Nitrogen = P₍₁₎ = 587 mmHg

                Partial pressure of Oxygen  = P₍₂₎ = 158 mmHg

                Partial pressure of Argon     = P₍₃₎ = 7.00 mmHg

Putting these values in eq 1.

                                 Total Pressure = 587 mmHg + 158 mmHg + 7 mmHg

                                 Total Pressure = 752 mmHg

Please help with this answe i do not how to to do it it
Scrat [10]

Answer:

1.20 M (3 s.f.)

Explanation:

In this question, we are trying to find the concentration of KCl after dilution. Note that the number of moles of KCl does not change.

g \div  \frac{g}{mol}  = g \times  \frac{mol}{g}  = mol

Number of moles of KCl

= 44.7 ÷74.55

= 0.59960 mol (5 s.f.)

New volume

= 500 mL

= (500 ÷1000) L

= 0.5 L

Concentration after dilution

= 0.59960 ÷0.5

= 1.1992 mol/L

= 1.20 M (3 s.f.)

* M is the symbol for Molarity, which is also equal to mol/L
