Minerals form by erosion of rocks.The erosion process includes water and other rocks rubbing against other rocks.
The only two elements that are liquid at room temperature are Bromine (Br) and Mercury (Hg).
Answer:Al3+ indicates an ion of aluminum having a charge of + 3. I.e., since an aluminum atom normally has 13 protons and 13 electrons, this ion has 10 electrons (-10 charge) and 13 protons (+ 13 charge) giving it a charge of + 3 (-10 + 13 = +3).
Explanation:
Answer:
When the concentration of reactants is equal to the concentration of the products. [ when reaction rate is zero ]
Explanation:
This is only observed in a reversible reaction
Answer:
Conservation of mass can be checked in an experiment . There are three steps to do it in a best way:
1. Weigh all the equipment and materials required in the experiment before the experiment.
2. Avoid spillage and evaporation during the experiment.
3. Weigh all the equipment and materials after the experiment.
If the mass is conserved then weight from step 1 is equal to weight from step
