effect of force
How copper oxide should be added to boiling sulphuric acid?
By using a spatula and stire it gently by using a stirring rod.
Why when you heat up copper sulphate does it turn blue?
You have this backwards. Copper sulfate, CuSO4.5H2O is blue. When it is gently heated, it loses water and turns white.CuSO4.5H2O --> CuSO4 + 5 H2O.The white substance is anhydrous copper sulfate. If you put water on it it turns blue again.
What happens when you gently caress a baby more?
It'll be deeply traumatized for the rest of it's life.
What is the value of a copper 1943 penn?
If it's a genuine copper 1943 cent, it's worth thousands of dollars. However, whenever something is that rare and valuable, people make fakes. One method is to copper-plate a regular steel cent. If the coin is magnetic, it's not made of copper. Another method is taking a 1948 cent and gently filing off the left half of the number 8.
What happens to the speed of a motor car when brakes are gently applied?
The speed of the motor vehicle is gently slowed down. The more aggressive the brakes are applied the faster the vehicle slows down eventually coming to a full stop.
What happens when your nipples itch but hurt at the same time?
That happens to me all the time! The best way to make it stop is if you gently rub a little bit of lotion on the nipple. I hope i helped :) !
Can sulphuric acid dissolve plastic?
Yes, although some damage to the pipes may occur after prolonged exposure. If you can rinse the pipes with water while not actively using the muriatic acid (which is just hydrochloric acid) it would probably be fine. Also, if the muriatic acid is already diluted before passing through the pipes, it will definitely be fine. The resistance to concentrated hydrochloric acid is rated as "good," but its resistance to dilute solution is rated "excellent."See the Web Links to the left for a chart of chemical resistance for PVC.
How do you make copper oxide from copper carbonate?
Carbonate Decomposition Aim: To investigate the decomposition of a carbonate. Equipment: · Copper Carbonate (CuCO3) · Limewater · Bunsen Burner · Matches · Test tubes · Clamp and stand · Hydrochloric Acid · Electronic Scales Method: 1. Weighed Copper Carbonate by taring empty test tube. 2. Placed some Copper Carbonate in a test tube fitted with gas delivery tube and stopper. 3. Clamped the test tube to the stand at a slight angle. 4. Half filled another test tube with limewater and placed the other end of gas delivery tube into it. 5. Using a small blue flame gently heated the carbonate. Observed what happened. 6. Removed gas tube from limewater before turning off the Bunsen burner. 7. Allowed to cool 8. Weighed the remaining Copper Carbonate. 9. Added approximately 5ml of Hydrochloric Acid to the solid residue (Copper Oxide) from the decomposition reaction. 10. Transferred a small amount of original Copper Carbonate to new test tube and added same amount of Hydrochloric Acid to that. Recorded observations. Results: Observations from Decomposition: The limewater turned milky. Observations from HCl & Copper Oxide: Small bubbles. Hardly a reaction. Observations from HCl & Copper Carbonate: Bubbles & fizzing. Small amount of heat generated. Turned milky green in colour. Reacted immeadiately. Conclusion: The limewater proved that Carbon Dioxide was produced as a result of thedecomposition reaction. The Copper Oxide test showed that theoretically there should be no reaction with HCl. Copper Carbonate, however, theoretically, should react. Evaluation: Overall, the experiment was a success except for the fact that the HCl shouldn'thave reacted with the Copper Oxide but did. This is probably due to the fact there was some Copper Carbonate still stuck to the side of the test tube and the HCl reacted with that.
Does heating copper II sulfate produce a chemical change or physical change?
Heating Copper Sulfate gently drives off the water of crystallization leaving an amorphous white powder. This is purely a physical reaction. Heating this powder strongly will cause a chemical reaction liberating sulfur dioxide and oxygen, leaving black copper(II)oxide: 2CuSO4 >2CuO + 2SO2 + O2
What is comparative and superlative of gently?
