Answer:

2RbNO2 + BaCO3 → Rb2CO3 + Ba(NO2)2

Explanation:

The balanced reaction equation is shown below;

2RbNO2 + BaCO3 → Rb2CO3 + Ba(NO2)2

This reaction is possible because the reduction potential of Rb is -2.98V while that of Ba is –2.92 V. Hence Rb can displace Ba from its salt solution.

The equation is balanced since the number of atoms of each element on the left and right hand sides of the reaction equation are equal.

Answer:

John Dalton

Explanation:

John Dalton in 1808 suggested that all matter consists of tiny particles called atoms and that the atoms of a specific element are identical.

He postulated the Dalton's atomic theory which has the following important parts;

All matters consists of indivisible particles called atoms
Atoms of the same element are similar and are different from atoms of other elements.
Atoms can neither be created nor destroyed.
Atoms combine in simple whole ratios to form compounds.

Use bond energies to determine δhrxn for the reaction between ethane and chlorine. ch3ch3(g)+cl2(g)→ch3ch2cl(g)+hcl(g)

STALIN [3.7K]

For this reaction to proceed, the following bond breaking should occur:

*one C-H bond
* one Cl-Cl bond

After, the following bond formations should occur:
*one C-Cl bond
*one H-Cl bond

Now, add the bond energies for the respective bond energies which can be found in the attached picture. For bond formations, energy is negative. For bond breaking, energy is positive.

ΔHrxn = (1)(413) + (1)(242) + 1(-328) + 1(-431) = <em>-104 kJ</em>
