What is the color change when hydrated ferrous sulphate is heated?
When hydrated ferrous sulfate is heated, it loses its water molecules and undergoes thermal decomposition. The color change is from pale green (hydrated) to white (anhydrous).
How many moles of anhydrous copper sulfate is produced when 6.4 moles of hydrated copper sulfate is heated?
When hydrated copper sulfate is heated, it loses its water molecules to form anhydrous copper sulfate. Since the molar ratio between the two forms is 1:1, if 6.4 moles of hydrated copper sulfate is heated, 6.4 moles of anhydrous copper sulfate will be produced.
What is a reversible chemical reaction for the heating of hydrated copper sulphate?
The reversible chemical reaction for the heating of hydrated copper sulfate (CuSO4·5H2O) is: CuSO4·5H2O (blue) ⇌ CuSO4 (white) + 5H2O The blue hydrated copper sulfate loses its water molecules when heated to form white anhydrous copper sulfate and water molecules are released. This reaction is reversible, meaning the white anhydrous copper sulfate can regain water molecules to reform the blue hydrated copper sulfate under appropriate conditions.
Is NaCl decreases when heated to 90 degree C?
No, NaCl (sodium chloride) does not decrease when heated to 90 degrees Celsius. Heating NaCl at this temperature will not cause it to decompose or decrease in quantity – it will remain the same compound, only in a different physical state (solid to liquid).
Is a continuous spectrum produce a heated ionic compound?
Yes, a continuous spectrum can be produced by a heated ionic compound. When an ionic compound is heated, electrons can be excited to higher energy levels, and as they return to their ground state, they emit light across a wide range of wavelengths, resulting in a continuous spectrum.
What is the color change when hydrated ferrous sulphate is heated?
When hydrated ferrous sulfate is heated, it loses its water molecules and undergoes thermal decomposition. The color change is from pale green (hydrated) to white (anhydrous).
A heated metal block volume decreases or increases?
It decreases
When air is heated air pressure decreases because the molecules?
when air is heated ,air pressure decreases because the molecules are
When copper is heated in oxygen the compound formed is?
When copper is heated in oxygen, the compound formed is copper oxide.
How many moles of anhydrous copper sulfate is produced when 6.4 moles of hydrated copper sulfate is heated?
When hydrated copper sulfate is heated, it loses its water molecules to form anhydrous copper sulfate. Since the molar ratio between the two forms is 1:1, if 6.4 moles of hydrated copper sulfate is heated, 6.4 moles of anhydrous copper sulfate will be produced.
What happens to the resistance of a metal when it is heated?
its resistence considerably decreases
What is a reversible chemical reaction for the heating of hydrated copper sulphate?
The reversible chemical reaction for the heating of hydrated copper sulfate (CuSO4·5H2O) is: CuSO4·5H2O (blue) ⇌ CuSO4 (white) + 5H2O The blue hydrated copper sulfate loses its water molecules when heated to form white anhydrous copper sulfate and water molecules are released. This reaction is reversible, meaning the white anhydrous copper sulfate can regain water molecules to reform the blue hydrated copper sulfate under appropriate conditions.
Why did barium chloride lose mass after being heated?
Crystallised BaCl2·2H2O will be de-hydrated when heated, loozing 2H2O per mol BaCl2·2H2O
What is the name of the compound formed when magnesium and sulfur are heated?
The compound formed when magnesium and sulfur are heated is magnesium sulfide (MgS).
What happens to a colour of a solute molecules when the solvent evaporates or boils?
The color of an anhydrous compound is sometimes different from the hydrated compound.
What gas or liquid is released when hydrated copper sulphate is heated?
Water vapors and sulfur dioxide are released.
Is NaCl decreases when heated to 90 degree C?
No, NaCl (sodium chloride) does not decrease when heated to 90 degrees Celsius. Heating NaCl at this temperature will not cause it to decompose or decrease in quantity – it will remain the same compound, only in a different physical state (solid to liquid).
