In order to get HgO you would need 2Hg+1O2=2HgO. Since oxygen is diatomic you need two when it stands alone causing you to need two mercuries to balance out the reactants and the product I hope this helps
The burning of methane gas, given below, is a redox reaction. which part of the reaction illustrates oxidation, Ch4+O2---CO2+H2O<span>CH4---CO2</span>
Answer:
8L
Explanation:
Using Boyle's law which states that the volume of a given mass of gas is inversely proportional to the pressure, provided temperature remains constant
P1V1= P2V2
P1 = 2atm, V1 = 12L ,
P2 = 3atm , V2 =
12 × 2 = V2 × 3
Divide both sides by 3
V2 = 24 ÷ 3
V2 = 8L

Answer:
![n= \frac{m}{ \rho }* \frac{1 mol}{22.4 L}](https://tex.z-dn.net/?f=n%3D%20%5Cfrac%7Bm%7D%7B%20%5Crho%20%7D%2A%20%5Cfrac%7B1%20mol%7D%7B22.4%20L%7D)
Explanation:
Assuming that all caculations are at normal pressure and -1.72°C :
![n= \frac{m}{ \rho }* \frac{1 mol}{22.4 L}](https://tex.z-dn.net/?f=n%3D%20%5Cfrac%7Bm%7D%7B%20%5Crho%20%7D%2A%20%5Cfrac%7B1%20mol%7D%7B22.4%20L%7D)
