The interaction between calcium carbonate and hydrochloric acid can be represented by the chemical equation,

    CaCO3 + 2HCl --> CaCl2 + H2O + CO2

Calcium carbonate has a molecular weight of 100 g/mol, while hydrochloric acid's molecular weight is 36.45 g/mol. According to the equation, 100 g of calcium carbonate reacts with 72.9 g of hydrochloric acid.

    x = (4 g HCl)(100 g CaCO3 / 72.9 HCl)
      x = 5.49 g

Final result: 5.49 g

Result:

5.486 grams of CaCO3 are required for 4 grams of HCl.

Clarification:

The balanced chemical equation illustrating the reaction between hydrochloric acid and calcium carbonate is:

CaCO3 + 2HCl -> CaCl2 + CO2 + H2O

This indicates that one mole of CaCO3 reacts with two moles of HCl to yield one mole each of CaCl2, CO2, and H2O.

Two moles of HCl necessitate two moles of CaCO3.

In terms of mass, we express this as:

72.9 grams of HCl correspond to 100 grams of CaCO3.

1 gram of HCl requires (100/72.9) grams of CaCO3.

4 grams of HCl demand ((100*4)/72.9) grams of CaCO3.

Thus, 4 grams of HCl need 5.486 grams of CaCO3.

KiRa [2711]
Hello, in this context regarding the decomposition of phosphorus pentachloride: Considering the equilibrium constant is given, along with the initial concentration of phosphorus pentachloride, we can establish the law of mass action. To analyze the changes in concentration and the equilibrium state, an ICE table will be used. This will lead us to determine the equilibrium concentration of phosphorus pentachloride, which will ultimately allow us to compute the percent decomposition. Best regards.

At 900.0 K, the equilibrium constant (Kp) for the following reaction is 0.345. 2SO2 + O2(g) → 2SO3(g) At equilibrium, the partia
lorasvet [2515]

Answer:

The partial pressure of SO₃ is measured at 82.0 atm.

Explanation:

The equilibrium constant Kp is defined as the ratio of the equilibrium pressures of the gaseous products, each raised to the power of their respective coefficients in the reaction, divided by the pressures of the gaseous reactants raised to their coefficients.

For the given reaction,

2 SO₂(g) + O₂(g) → 2 SO₃(g)

Kp = 0.345 = \frac{(pSO_{3})^{2} }{(pSO_{2})^{2} \times pO_{2} }\\pSO_{3} = \sqrt[]{0.345 \times (pSO_{2})^{2} \times pO_{2} } \\pSO_{3} = \sqrt[]{0.345 \times (35.0)^{2} \times 15.9 } \\pSO_{3} = 82.0 atm

The electron configuration of an element is 1s22s22p4. Describe what most likely happens when two atoms of this element move tow
castortr0y [2743]

Answer:

Cuando dos átomos se acercan entre sí, se genera un compuesto al compartir pares de electrones que cada uno de los átomos aporta, permitiéndoles alcanzar los 8 electrones de valencia (octeto) en su capa externa.

Explanation:

La configuración electrónica del elemento puede escribirse de la siguiente manera;

1s²2s²2p⁴

La configuración electrónica dada es equivalente a la del oxígeno, por lo tanto, tenemos;

El número de electrones en la capa de valencia = 2 + 4 = 6 electrones

Por consiguiente, cada átomo necesita 2 electrones para completar sus 8 electrones (octeto) en la capa externa.

Al acercarse los dos átomos, reaccionan y se combinan para formar un compuesto al compartir 4 electrones, 2 de cada átomo, de modo que cada átomo obtenga 2 electrones adicionales en su órbita externa en el nuevo compuesto y así se logre la configuración estable de octeto para cada uno de los átomos en el compuesto recién formado.

What mass of carbon dioxide (co2) can be produced from 86.17 grams of c6h14 and excess oxygen?
lorasvet [2515]
2C6H14 + 13O2 ---> 6CO2 +14H2O

Calculating the molar mass of C6H14: M(C6H14)=12.011*6 +1.008*14 ≈ 86.17 g/mol

Thus, 86.17 g of C6H14 corresponds to 1 mole.

                                  2C6H14 + 13O2 ---> 6CO2 +14H2O
based on the equation        2 mol                            6 mol
according to the question    1 mol                            3 mol

To determine M(CO2): M(CO2)= 12.011 + 2*15.999= 44.009 g/mol
Therefore, 3 mol CO2*44.009 g/1 mol CO2 ≈ 132.0 g CO2
Final answer: 132.0 g CO2
