Answer:
A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. ... A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
Answer:
A water molecule consists of three atoms; an oxygen atom and two hydrogen atoms, which are bond together like little magnets. The atoms consist of matter that has a nucleus in the centre. one mole of water contains 6.02 x 1023 MOLECULES of water But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.Feb 12, 2003

Answer:
Yes
Explanation:
Why is glycerol more viscous than water?
The glycerine is more viscous than water because due to presence of hydrogen atoms , we all know that glycerine has more hydrogen bonding than water molecule , which makes an aggregation which means that glycerine is more viscous than water , in simple words glycerine can't flow as that of water molecule.
Answer:
Energy
Explanation:
The heat required to change the phase of a substance is given by the equation:
Q= mL (Q= Heat required, m= mass, L= Latent Heat of Fusion/Evaporation/Anything else).
So, according to your values:
Q= 3.0 kg x 333 kJ/Kg
So, Q= 999 kJ
For Iron:
For Oxygen:
These are the two chemical symbols for the two elements found in Iron Oxide.
