Is a mixture of sugar and chalk heterogeneous?
No, a mixture of sugar and chalk is considered heterogeneous. This is because sugar and chalk do not dissolve in each other, so they would have visible differences and not form a uniform composition throughout the mixture.
Why chalk does not react with HCl?
Chalk is primarily made of calcium carbonate, which is a stable compound. When chalk comes in contact with hydrochloric acid (HCl), it does not react because calcium carbonate is insoluble in acidic solutions. This lack of reactivity is due to the stable structure of calcium carbonate molecules.
Can chalk dissolve in HCl and why?
No, chalk (calcium carbonate) does not dissolve in hydrochloric acid (HCl) because calcium carbonate is insoluble in acids. When HCl is added to chalk, it will react with the calcium carbonate to form calcium chloride, water, and carbon dioxide gas, but the chalk itself will not dissolve.
Is mixture of chalk and water is a colloid?
No, a mixture of chalk and water is not a colloid. A colloid is a mixture where one substance is evenly dispersed in another substance, forming a homogeneous mixture. Since chalk does not form a homogeneous mixture with water, it is not considered a colloid.
What is the ionic equation for hcl ch3nh2?
The ionic equation for the reaction between hydrochloric acid (HCl) and methylamine (CH3NH2) is: HCl + CH3NH2 -> CH3NH3+ + Cl-

HCL CUSO4 equation?
The chemical equation for the reaction between hydrochloric acid (HCl) and copper (II) sulfate (CuSO4) is: 2 HCl + CuSO4 -> CuCl2 + H2SO4
Is HCl gas a mixture or a compound?
