The pores of the organisms' tissues are filled when these minerals precipitate out of the water. Two common types of ...
Explanation:
This statement is false. When water is decomposed into hydrogen and oxygen; these gases are in a position of combining again to reform water. Water is a molecule consisting of one atom of oxygen bound to two hydrogen atoms. The atoms are joined by covalent bonds; however they have addition hydrogen bonds between the partial negative oxygen and the partial positive hydrogen atom.
Answer:
•Matter is made up of smallest indivisible particle named as atom.
•All atom of same element have equal atomic mass and identical properties.
•Compounds are made up two or more different types of atoms.
•In a chemical reaction rearrangement of atoms takes place.
•Atoms of different elements differ in mass and size.
mass of the gas = 10 g
<h3>Further explanation</h3>
<em>The law of conservation of mass :</em>
<em>In a closed / isolated system, the total mass of the substance before the reaction will be equal to the total mass of the reaction product.</em>
Reaction
mass before reaction=mass after reaction
