Of course; 3 H2 + N2 -------2 NH3
Yes, the combination of hydrogen and oxygen to form water is a chemical change. In this reaction, new bonds are formed and energy is released, resulting in a new substance with different properties than the original elements.
Mixing is a physical process.
No, the combining of two hydrogen atoms is a chemical bond.A chemical change is when bonds are broken and new bonds are formed between different atoms.examples of this are:Mixing an acid and a base (giving a salt and water)Photosynthesis (CO2 and O2 making sugars for a plant)Oxidation (i.e. rust)How you can tell when a chemical change has occurred?:Change of colorchange of odorchange of color (e.g. rusting changes metal from a silver color to a reddish-brown color)and others - see teacher (judging by the question, you are in school?)Hope this helped :)
Combing hair does not result in a significant build-up of electric charge, so the girl's hair is not typically charged negatively or positively as a result of combing.
you handle them by combing them to make one great drug

Oh honey, combing your hair is about as much of a chemical change as putting on socks. It's just a physical change, not a chemical one. Chemical changes involve the rearrangement of atoms, not just moving your strands around with a comb. So go ahead and comb away, you're not causing any chemical chaos up there.
Hydro can mean several things such as;a combing meaning of waterIt is also used in a formation of compound wordsBy combing words such as ; Hydropower, Hydroelectricity, Hydromorphone, Hydrogen, etc.

The kids enjoy combing the beach for seashells each summer. She's in the bathroom combing her hair and brushing her teeth. Dad spent hours combing the closet for his red tie. Police are combing the area hoping to find the missing child. Before he even had his diploma, he was combing the want ads for a job in his field.
The wool combing machine was invented in 1789. Edward Cartwright who invented the wool combing machine.
Oh, dude, combing your hair is totally a physical change! I mean, you're literally rearranging the strands of your hair with a comb, so yeah, it's not like your hair magically grows longer or changes color just because you ran a comb through it. It's like giving your hair a little makeover without any magical potions or spells, just good ol' combing action.
no excessive combing will break your hair making it harder to grow

The poem entitled Combing is written by Gladys Cardiff. Its summary is all about a mother combing her daughter's hair.
Combing is a technique that has been used in the preparation of textiles for centuries. Essentially, combing is a process that helps to smooth and prepare fibres for use in spinning. Combing also helps to separate short fibres from longer ones, which also helps to make the process of spinning much easier.
