Answer:
see below
Explanation:
1. 1 mol Mg = 24.31 g = 6.02 *10^23 atoms
calculate the number of atomsin 80.45g Mg
Numberof atoms = 6.02*10^23 Mg atoms / 24.31 g * 80.45 g
= 1.99*10^24 atoms
2.1 mol C-12 = 12.01g = 6.02 * 10^23 atoms
calculate the mass using
= 12.01 g C / 6.02*10^23 atoms * 100 atoms
= 1.99 * 10^-21 g
Answer:
Explanation:
Hello!
In this case, since this a reaction in which the oxidation state of the metals is changing, we need to apply a redox method for which:
Thus, the result is:
Regards!
Answer:
the law of conservation mass states that the mass of an isolated system cannot be created nor destroyed by any chemical reaction or physical transformation.
thus, there must be an equal number of atoms of an element present on both sides of the equation.
I think the correct answer would be false. <span>Gases do expand because they do not have an absolute volume. However, liquids do not expand to fill their container, they just fill and follows the shape of the container. Hope this answers the question.</span>
The most acidic is bleach because the ph level is a lot higher then 7 and a ph of 7 is normal (non-acidic).
