Answer:
118 elements
Explanation:
Of these 118 elements, 94 occur naturally on Earth.
Answer:
adding silver ions , adding chloride ions, removing chloride ions and removing silver chloride.
Explanation:
Barium sulfate is an insoluble ionic compound since it is insoluble in water.
We can differentiate barium ions and sulfate ions away from the surface if we add a small amount of solid barium sulfate is mixed with water and shaken.
The action would shift this reaction away from solid barium sulfate and toward the dissolved ions are adding silver ions , adding chloride ions, removing chloride ions and removing silver chloride.
An ionic and covalent quality has in every molecular bond.
In barium sulfate barium has lowest electronegativities.
Oxygen has highest electronegativities.
so the bond between both barium and sulfate is ionic in character.
Answer:
Shape of the enzyme and its active site
Explanation:
Answer:
76.0%
Explanation:
Let's consider the following reaction.
CaCO₃(s) ⇄ CaO(s) + CO₂(g)
At equilibrium, the equilibrium constant Kp is:
Kp = 1.16 = pCO₂ ⇒ pCO₂ = 1.16 atm
We can calculate the moles of CO₂ at equilibrium using the ideal gas equation.
From the balanced equation, we know that 1 mole of CO₂ is produced by 1 mole of CaCO₃. Taking into account that the molar mass of CaCO₃ is 100.09 g/mol, the mass of CaCO₃ that reacted is:
The percentage by mass of the CaCO₃ that reacted to reach equilibrium is:
hola, esta pregunta es bastante difícil pero está bien, no lo sé, lo siento :) :)
