What happens if sodium hydroxide is mixed to the lime water?
Any reaction occur.
What is the side effect on human body when use alum in drinking water for purification of water .?
alum when mixed with water produces H2S gas which is highly toxic . although this is a gas and is released in air but some of it gets dissolved in water to produce H2SO4 acid and makes the water acidic. alum treated water needs more treatment through conventional water purifirs to remove any traces of H@S and H2SO4
What would happen if you mixed water with household bleach and bleached your hair?
Hair loss, a severely burned scalp, and hospitalization will occur if one mixed water and household bleach and applied it to human hair.
How do you prepare the 1.25 H2SO4 from 98 ww H2SO4?
Mix 120 g sulfuric acid with water to 1000 mL.
When ice changes to water the link up of atoms does or does not change?
The bonds between hydrogen and oxygen atoms of individual water molecules do not change when liquid water changes to ice. This is a physical change called freezing, and does not cause any chemical changes to occur. Only chemical changes can cause changes in chemical bonds.
How do the changes that occur when water is mixed with salt differ from the changes that result when water is mixed with sodium?
When water is mixed with salt, the salt dissolves in the water but whenwater is mixed with sodium, the sodium reacts violently with water.
How do the changes that occur in when water is mixed with salt differ from the changes that result when water is mixed with sodium?
Sodium chloride is soluble in water but a chemical reaction doesn't occur.Sodium react chemically with water.
Which of the following is an acid - ammonia - potassium hydroxide - sulfuric acid - lithium hydroxide?
Ammonia (NH3)- when mixed into water - forms a basic solution.potassium hydroxide (KOH)- when mixed into water - forms a basic solution.lithium hydroxide (LiOH) - when mixed into water - forms a basic solution.Sulfuric acid (H2SO4) - when mixed into water - forms an acid solution.
What happen when water and cooper mixed?
Any reaction occur.
What is formed when calcium carbonate and sulphuric acid is mixed?
Calcium sulfate, carbon dioxide and water. CaCO3 + H2SO4 --> CaSO4 + CO2 + H2O
Why HCl doesn't react with copper but H2SO4 does?
In general, copper will not displace hydrogen from water or from acids, but in the case of hot, concentration H2SO4 a reaction will occur with copper. Why? Because hot, concentrated H2SO4 will act as an oxidizing agent to oxidize the copper to copper cation. HCl cannot do this.
What change of state occur when water changes to gas?
gas
What is the balance equation for H2SO4 by KOH?
H2SO4 is a strong acid commonly known as sulfuric acid. NaOH is a strong base commonly known as sodium hydroxide. When the two are mixed at a ratio of 1mol of H2SO4 to 2 mols of NaOH, a neutralization reaction occurs.
What happens if sodium hydroxide is mixed to the lime water?
Any reaction occur.
Where does the largest temperature change occur in the mixed layer and why?
At the bottom of the mixed layer, because this is where the mixed layer is seperated from the calm deep water below it.
What are the chemical formulas of the substances made when sulfuric acid and sodium hydroxide are mixed?
H2SO4 + 2 NaOH --> Na2SO4 + H2O forms sodium sulfate and water
What chemical changes will happen when salt water mixed with cement?
magnesium sulphate
