What else can I help you with?
Does this chemical recation PbCl2 Pb Cl2 obey the law of conservation of mass?
Yes, because the equation is balanced
What type of recation is rquired to bind two molecules of glycone together and release a molrcule of water?
This type of reaction is called a dehydration synthesis.
Is silver melts when using a blow torch a chemical or physical recation?
It is a physical reaction. Melting is a physical change because it does not change the chemical composition of the substance.
What evidences indicate that new substance has formed as a result of a chemical reaction?
how is cutting something in half or a new solution soution=when something is mixed together to make a new solution.this might n
What kind recation is 2KClO3 2KCl 3O2?
KClO3 - KCl + O2
Is making ice cubes an endothermic recation?
No. It is a physical change.
What do you do if someone touched you?
depent hows he/she to touch me recation depend on situation
What type of reaction takes place in stars?
a nuclear recation is formed
What evidence indicate that a new substance has formed as a result of a chemical reaction?
the recation is right

When fusion takes place?
The best example of it is sun which is highly ionised the recation takes place helium recats each other it gives hydrogen and hydogen rects with another molecule of hydrogen it gives hydrogen...

When you shake sugar and Sand together in a test tube you cause a?
physical mixture of the two substances, as they do not chemically react with each other. After shaking, the sugar and sand will be physically mixed together but can be separated by a process such as filtration.
A eat Mentos and soda and nothing happens what's wrong?
If you want mean "I ate some mentos and soda and nothing happened, what's wrong" Then I can tell you nothing is wrong. The recation happens because you are dropping the mentos into the soda (see Why_do_diet_coke_and_mentos_reactfor full details) and the digestion doesn't work like that. Also, the stomach acid won't let the reaction occur.
What type of nuclear reaction takes place in stars?
Nuclear fusion is the type of nuclear reaction that occurs in stars. Older stars with a collapsing center can exceed a temperature of one hundred million Kelvin.
