What else can I help you with?
A substance that does not dissolve in a solvent is said to be what in that solvent?
- Sand does not dissolve in water- Plastic does not dissolve in water- metals do not dissolve in water
Why are CuO and Fe2O3 soluble in water?
CuO and Fe2O3 are not soluble in water because they are both metal oxides with ionic bonds, which are generally insoluble in water. The high electronegativity of oxygen attracts the metal cations strongly, making it difficult for them to dissociate and form ions in water.
What is the oxidizing agent for the reaction CuO H2--Cu H2O?
In the reaction CuO + H₂ → Cu + H₂O, the oxidizing agent is CuO. This is because CuO, which contains copper in the +2 oxidation state, is reduced to elemental copper (Cu) as it gains electrons. Meanwhile, hydrogen (H₂) is oxidized to form water (H₂O), losing electrons in the process.
What two substances dissolve in water?
Salt and Sugar dissolve in water.
Does hydrophilic dissolve in waTER?
Yes, hydrophilic substances dissolve in water. Hydrophilic molecules are attracted to water molecules due to their polar nature, allowing them to form bonds with water and dissolve in it. This is in contrast to hydrophobic substances, which repel water and do not dissolve in it.
Chemical equations of hydrochloric acid and copper oxide?
The product is copper ii chloride alongwith water, CuO + 2HCl = CuCl2 + H2O
A substance that does not dissolve in a solvent is said to be what in that solvent?
- Sand does not dissolve in water- Plastic does not dissolve in water- metals do not dissolve in water
Does water and salt dissolve?
No, but salt does dissolve in water.
Do lipids dissolve water?
No. Lipids do not dissolve in water.
Does carbon dissolve in water?
No, carbon does not dissolve in water.
How many moles are there in 3.2g of CuO?
To find the number of moles, first calculate the molar mass of CuO by adding the atomic masses of copper (Cu) and oxygen (O) together. Then, divide the given mass of CuO (3.2g) by the molar mass to get the number of moles.
Does salt dissolve in tap water?
Yes it does dissolve in tap water. It can really dissolve in any water.
What precipitate is formed if you add HCl to CuO and then add BaCl2?
HCl and CuO form CuCl2 and H2O, BaCl2 does not react with CuCl2 so it may react with water so the precipitate are of Ba(OH)2 Added: But this is not the case because to dissolve CuO first you'll need a bit more acid to get it completely dissolved. If the solution would become neutral then Cu(OH)2 would precipitate at concentration of [Cu2+] more than 1.6*10-5 (because Ks=1.6*10-19) rather than Ba(OH)2 (Ks=10-10)
What are substances that dissolve in water?
Nutilite's vitamins dissolve in water.
Does cinnamon dissolve in water?
Yes, cinnamon does not dissolve in water.
Does lithium dissolve in water?
Yes, lithium does dissolve in water.
