When you burn paper you are chemically altering it so that is the correct answer. When you do all the other choices all of the components stay the same. Just because it changes shapes doesn't mean it'll change chemically toom
Answer:
I think that temperature will be cut in half.
When volume increases, pressure decreases. As pressure decreases, temperature decreases. So if you double volume, pressure is halved and so will the temperature. I'm new to this, but I think that's the answer . Tell me if I'm right good luck!
Answer:
each of more than one hundred substances that cannot be chemically interconverted or broken down into simpler substances and are primary constituents of matter. Each element is distinguished by its atomic number, i.e. the number of protons in the nuclei of its atoms.

Answer:
About 96 grams per mole
Explanation:
The chemical formula of ammonium carbonate is . This means that breakdown of moles of atom per mole of molecule is:
2 moles of nitrogen, with a molar mass of around 14
8 moles of hydrogen, with a molar mass of around 1
1 mole of carbon, with a molar mass of about 12
3 moles of oxygen, with a molar mass of about 16
The molar mass of ammonium carbonate is therefore:
2(14)+8(1)+1(12)+3(16)=28+8+12+48=about 96
Hope this helps!
