Why is the PH for the reaction of sodium oxide and water higher than calcium oxide and water?
The pH for the reaction of sodium oxide and water is higher than that of calcium oxide and water because sodium hydroxide (the product of sodium oxide and water) is a stronger base than calcium hydroxide (the product of calcium oxide and water). Sodium hydroxide dissociates more in water, releasing more hydroxide ions, thereby increasing the pH of the solution.
Which is more expensive sodium chloride or calcium chloride?
Calcium chloride is generally more expensive than sodium chloride. This is because calcium chloride is less abundant and requires more complex extraction processes compared to sodium chloride, which is commonly found in salt deposits and seawater. Additionally, calcium chloride is often used in industrial applications that command a higher price.
How do the atoms of calcium compare to the atoms of sodium?
Atoms of calcium have 20 protons and electrons, while atoms of sodium have 11 protons and electrons. Calcium is larger in size and has a higher atomic mass compared to sodium. Both atoms are metals and are part of the alkali earth and alkali metal groups, respectively.
Which base is stronger Calcium or Aluminum or Magnesium or Sodium?
Calcium is a stronger base compared to Aluminum, Magnesium, and Sodium. This is because it has a higher affinity for accepting a proton (H+) and can release hydroxide ions more readily in solution, making it a stronger base.
Will calcium bond with chlorine and sodium?
Yes, calcium can form ionic bonds with chlorine and sodium. Calcium will lose two electrons to become a Ca2+ ion, while chlorine will gain one electron to become a Cl- ion, and sodium will lose one electron to become a Na+ ion. These ions can then form ionic compounds such as calcium chloride and calcium sodium.
Which is more likely to form a cation between sodium and calcium?
Sodium is easier to form Na+ then Calcium forming Ca2+. The main reason is because Sodium has got 1 valence electron, which is more unstable than Calcium having 2 valence electrons. It requires less energy to remove one electron from Sodium than two electrons from Calcium. Therefore, Sodium is higher than Calcium in the reactivity series.
Why does calcium oxide have a higher melting point than sodium chloride?
Calcium oxide has a higher melting point than sodium chloride because calcium oxide has stronger ionic bonds due to the higher charge of calcium ions (+2) compared to sodium ions (+1). The stronger ionic bonds in calcium oxide require more energy to break, resulting in a higher melting point.
Why is the PH for the reaction of sodium oxide and water higher than calcium oxide and water?
The pH for the reaction of sodium oxide and water is higher than that of calcium oxide and water because sodium hydroxide (the product of sodium oxide and water) is a stronger base than calcium hydroxide (the product of calcium oxide and water). Sodium hydroxide dissociates more in water, releasing more hydroxide ions, thereby increasing the pH of the solution.
What is the difference between the masses of sodium bicarbonate and calcium carbonate?
The mass of sodium bicarbonate (NaHCO3) is 84 grams/mol, while the mass of calcium carbonate (CaCO3) is 100 grams/mol. Therefore, calcium carbonate has a higher molecular mass compared to sodium bicarbonate.
What metal is more reactive sodium or calcium?
Sodium is more reactive than calcium. Sodium has a lower electronegativity and ionization energy compared to calcium, making it more likely to lose electrons and react with other substances. Additionally, sodium's outermost electron is in a higher energy level, making it easier to remove.
Which is more expensive sodium chloride or calcium chloride?
Calcium chloride is generally more expensive than sodium chloride. This is because calcium chloride is less abundant and requires more complex extraction processes compared to sodium chloride, which is commonly found in salt deposits and seawater. Additionally, calcium chloride is often used in industrial applications that command a higher price.
Is calcium a harder metal than sodium?
Brinell hardnesses, in MPa: Ca: 167 Na: 0.69
What is the reactivity series for copper and calcium and sodium and potassium and lithium?
The reactivity series from highest to lowest reactivity is: potassium, sodium, calcium, magnesium, aluminum, zinc, iron, lead, copper, silver, gold. In this series, copper is less reactive than calcium, sodium, potassium, and lithium. Copper will not displace these metals from their compounds in solution (e.g., copper will not displace calcium from calcium chloride).
Why does magnesium ribbon not react with sodium sulphate solution?
as a displacement reaction has to occur when the metal is higher in the reactivity series thatn the metal in the salt. With your question this is not the case as sodium is higher than magnesium and so nothing will take effect.
Which element is more likely to react with oxygen Sodium or Calcium please explain if you can thank you?
Sodium. Sodium is more reactive than calcium, because sodium has one valence electron whereas calcium has two valence electron. It is easier to lose one electron and react with oxygen and form sodium oxide, compared to losing two electrons and from calcium oxide.
Does calcium have a lower first ionization energy level than sodium?
No. Calcium has TWO valence electrons, and Sodium has ONE. It is lot easier to take off one, than two you see. However, the second ionization energy of calcium IS however than the second ionization energy of Sodium. ;)
Are sodium calcium and chromium metals nonmetals or metalloids?
Sodium and calcium are metals, while chromium is a metal.
