Answer:

Atomic mass of Cl = 35.46 g/mol

Explanation:

From the given information:

Carbon tetrachloride CCl_{4} contains one carbon (C) and for chlorine (Cl) atoms

11.818 g of Cl combines with 1.000 g of C-12

Moles of C :

= \frac{Mass\ C}{Atomic\ Mass} =\frac{1.000g}{12g/mol} =0.0833moles

Molar ratio of C:Cl = 1:4

Therefore, moles of Cl is:

4(0.0833) = 0.3332moles

Atomic mass of Cl is:

\frac{Mass\ Cl}{moles\ Cl} =\frac{11.818g}{0.3332moles} =35.46 g/mol

If copper is heated with iron oxide there is no obvious reaction because

copper is less reactive than iron.

On a reactivity chart, copper is far below iron. This makes it impossible for a replacement reaction to occur, so the equation doesn't change.

I hope I helped!

Carbon dioxide gas reacts with liquid water to produce aqueous carbonic acid.” Which chemical equation correctly translates this
r-ruslan [8.4K]
Last option:
CO2 (g) + H2O (l) -> H2CO3 (aq)

In the brackets:
g = gas,
l = liquid,
s = solid,
aq = aqueous.

So,
CO2 (g) = carbon dioxide gas
H2O (l) = liquid water
H2CO3 (aq) = aqueous carbonic acid

Draw the mechanism for the acid-catalyzed reaction of acetic acid (ethanoic acid) with the methanol to yield methyl acetate (met
timama [110]

When ethanoic acid react with methanol in the presence of H⁺ or heat it gives methyl ethanoate and water.

<h3>What is Balanced Chemical Equation ?</h3>

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

Now write the chemical equation

CH₃COOH + CH₃OH ⇄ CH₃COOCH₃ + H₂O

Here

CH₃COOH is Ethanoic acid (Acetic acid)

CH₃OH is Methanol (Methyl Alcohol)

CH₃COOCH₃ is Methyl ethanoate (Methyl Acetate)

H₂O is water

Thus from the above conclusion we can say that When ethanoic acid react with methanol in the presence of H⁺ or heat it gives methyl ethanoate and water.
