Answer:
The law of conservation of mass
Explanation:
A chemical equation is an expression of the net composition change associated with a chemical reaction. It shows how a certain amount of reactants yields a certain amount of products. Both of these amounts are measured in moles. Chemical equations often contain information about the state of the reactants: solid, liquid, gas, or aqueous. In addition, they always adhere to the law of conservation of mass, which holds that matter can change form, but cannot be created or destroyed.
Atoms contains small, negatively charged particles. His experiment showed that an atom contains negatively charged particles which was later known as electrons. This was confirmed by the Cathode Ray Experiment he conducted.
It is 2 KJ
It is because the formula is :
q=m∆Hf
where m is the mass and ∆Hf is the heat fusion.
So, we get:
q=80×25
q=2000J or 2 KJ
Answer:
without being wordy, CARBON makes Only 4 and Always 4 bonds. If you want to count electrons & so on, go ahead, but in the end the
Primary Rule In Organic Chemistry is
Carbon makes 4 bonds. Check the OCTET RULE and so on to see if that gives you insight as to why, and a more complete answer. OK?
