Their are 18 covalent bonds in a molecule of cyclohexane
Answer:
CH4+ 2Cl2→CH2Cl2+ 2HCl
Explanation:
mass is 132.8`125
as methane and dichlormethane has the same molar ration 1 to 1
mol of ch4 is 1.5625
so 1.5625 times mr of ch2cl2 is 132.8125
Answer: False
Explanation: The density of the liquid will always be the same, no matter how much of the liquid you have.
For example, the density of the water in a pool is the same density as the water in a small cup.
In chemical changes molecules in the reactants interact to form new substances, which mean means are broken up to form new bonds. No atoms are created or destroyed while undergoing the chemical change. In a physical change more like a state of change meaning shape, size or anything that effects how the object looked before then no new substances are formed.
