Answer:

"0.24 J/g.k" is the appropriate solution.

Explanation:

Mass of substance,

m = 110.00 g

Heat,

q = 396 J

Change in temperature,

ΔT = 15.0°C

Now,

The specific heat will be:

⇒ $q=ms \Delta T$

On putting the given values, we get

⇒ $396=110.00\times s\times 15.0$

⇒ $396=s\times 1650$

⇒ $s=\frac{396}{1650}$

⇒ $=0.24 \ J/g.k$

Write the ions present in a solution of K2CO3. Express your answers as chemical formulas separated by a comma. Offset subscripts

meriva

Answer:

K ^+ , CO3 ^2-

Explanation:

The compound is potassium trioxocarbonate(IV).

It contains cation (potassium ion) and acid radical ( trioxocarbonate (IV) ion).

Since K is in group 1 of the periodic table, it loses one electron to form ion i.e K^1. trioxocarbonate IV ion has a charge of 2-.and so the ions of the compound are as shown in the answer above.

Predict the products of each of the following reactions and then balance the chemical equations.

Nookie1986 [14]

Answer: The chemical equations are given below.

Explanation:

For a: Fe is heated in an atmosphere of steam.

The chemical equation follows:

$3Fe(s)+4H_2O(g)\rightarrow Fe_3O_4(s)+4H_2(g)$

By Stoichiometry of the reaction:

3 moles of iron reacts with 4 moles of steam to produce 1 mole of iron (II,III) oxide and 4 moles of hydrogen.

For b: NaOH is added to a solution of $Fe(NO_3)_3$

The chemical equation follows:

$Fe(NO_3)_3+3NaOH\rightarrow Fe(OH)_2+3NaNO_3$

By Stoichiometry of the reaction:

1 mole of iron nitrate reacts with 3 moles of sodium hydroxide to produce 1 mole of iron hydroxide and 3 moles of sodium nitrate.

For c: $FeSO_4$ is added to an acidic solution of $KMnO_4$

The chemical equation follows:

$10FeSO_4+2KMnO_4+8H_2SO_4\rightarrow 5Fe_2(SO_4)_3+K_2SO_4+2MnO_4+8H_2O$

By Stoichiometry of the reaction:

10 moles of iron(II) sulfate reacts with 2 moles of potassium permangante and 8 moles of sulfuric acid to produce 5 moles of iron(III) sulfate, 1 mole of potassium sulfate, 2 moles of manganese oxide and 8 moles of water.

For d: Fe is added to a dilute solution of $H_2SO_4$

The chemical equation follows:

$Fe+H_2SO_4\rightarrow FeSO_4+H_2$

By Stoichiometry of the reaction:

1 mole of iron reacts with 1 mole of sulfuric acid to produce 1 mole of iron sulfate and 1 mole of hydrogen gas.

For e: A solution of $Fe(NO_3)_2$ and $HNO_3$ is allowed to stand in air.

The chemical equation follows:

$3Fe(NO_3)_2+4HNO_3\rightarrow 3Fe(NO_3)_3+NO+H_2O$

By Stoichiometry of the reaction:

3 moles of iron(II) nitrate reacts with 4 moles of nitric acid to produce 3 moles of iron(III) nitrate, 1 mole of nitric oxide and 1 mole of water.

For f: $FeCO_3$ is added to a solution of $HClO_4$

The chemical equation follows:

$FeCO_3+2HClO_4\rightarrow Fe(ClO_4)_2+CO_2+H_2O$

By Stoichiometry of the reaction:

1 mole of iron(II) carbonate reacts with 2 moles of perchloric acid to produce 1 moles of iron(II) perchlorate, 1 mole of carbon dioxide and 1 mole of water.

For g: Fe is heated in air

The chemical equation follows:

$2Fe+O_2\rightarrow 2FeO$

By Stoichiometry of the reaction:

2 moles of iron reacts with 1 mole of oxygen gas to produce 2 moles of iron(II) oxide.

Hence, the chemical equations are given above.
