Zinc sulphate can be made in a reaction between and an acid give the name of the acid?
zinc sulphate is made of a reaction between zinc and what acid
How to test the presence of the reaction of zinc and hydrochloric acid?
Place a zinc strip in a clean test tube and add dilute hydrochloric acid. The strip dissolves and the result is a colorless solution. The products are zinc chloride and gaseous hydrogen.
What is the function of dilute hydrochloric acid on zinc metal and sodium carbonate?
zinc reacts with dilute HCl to form H2. This works to reduce (add Hydrogens to ) a compound
When zinc metal is mined the rock that contains zinc is dissolved in acid to form a compound witch method could be used to separate the compound?
One method to separate the compound is through precipitation. By adding a reactant that forms a solid zinc compound, the compound can be filtered out, leaving other impurities in the solution. The solid zinc compound can then be dried and processed further to obtain pure zinc metal.
How to do a chemical test to distinguish between zinc powder and lead carbonate?
One method would be to add an acid such as HCl to each sample, and collect the gas produced. The zinc will produce hydrogen gas, which is flammable, while the lead carbonate will produce carbon dioxide, which is not flammable. Thus, one can distinguish between the compounds depending on whether or not the gas evolved in the reaction ignites.

zinc sulphate is made of a reaction between zinc and what acid
What product is formed when you add zinc to sulfuric acid?
If you add zinc to sulfuric acid, you will get hydrogen gas as a product.
What happen when you add few grains of zinc dust to 5 ml of dilute hydrochloric acid solution?
When you add zinc dust to dilute hydrochloric acid, a chemical reaction takes place where the zinc reacts with the hydrochloric acid to produce zinc chloride and hydrogen gas. This reaction is a type of single displacement reaction where the zinc replaces the hydrogen in the hydrochloric acid. The hydrogen gas is released as bubbles and you may observe fizzing or effervescence.
What would happen if you zinc into hydrohloric acid?
you would get Zinc Chloride, a salt. This is because when you add a metal to an acid, you get a salt (plus some water, which just dilutes the acid)
When you add zinc metal to hyrochloric acid does a chemical physical change occur?
Yes, hydrogen gas and zinc chloride are produced
How to test the presence of the reaction of zinc and hydrochloric acid?
Place a zinc strip in a clean test tube and add dilute hydrochloric acid. The strip dissolves and the result is a colorless solution. The products are zinc chloride and gaseous hydrogen.
How do you separate stearic acid from sand and zinc?
Add water and stir; the density of the stearic acid is very low - 0,843 g/cm3; consequently this insoluble in water acid float. Zinc and sand sits at the bottom of the beaker and the stearic acid can be separated.

zinc reacts with dilute HCl to form H2. This works to reduce (add Hydrogens to ) a compound
What is the value of a 1999 zinc penny?
1 cent. Since mid-1982 all US cents have been made of copper-plated zinc. Sometimes the plating comes off due to wear or exposure to acid but that doesn't add any value.
What is the change when you add zinc to about 5 ml of hydrochloric acid?
When zinc is added to hydrochloric acid, a chemical reaction takes place where zinc reacts with the acid to form zinc chloride and hydrogen gas. This reaction is exothermic, meaning it releases heat energy. The solution may also become warmer and bubbles of hydrogen gas will be evolved.
