I believe the correct answer from the choices listed above is option D. The molar mass of <span>Mg(ClO2)2 is obtained by adding the atomic masses of each atom in the compound and the result is 159.21 g per mole. Hope this answers the question. Have a nice day.</span><span />
Answer: the picture is work for number 1,2,4,5,7
Explanation: number 3: as the pressure in the volume decreases, the volume increases causing it to expand and eventually blow.
number 6: because the temperature and the amount of gas don’t change, these terms don’t appear in the equation. What Boyle’s law means is that the volume of a mass of gas is inversely proportional to its pressure. This linear relationship between pressure and volume means doubling the volume of a given mass of gas decreases its pressure by half.
hope this helps :))
Answer:
11.19 %
Explanation:
1 molecule water = 2 H + 1 O
If H = 1.008 u and O = 16.00 u, then
Water = 2H + 1 O = (2 × 1.008 u) + (1 × 16.00 u) = 2.016 u + 16.00 u = 18.02 u
The formula for mass percent is

So,
