Answer:
Water has a chemical formula of H2O . In here, there are two hydrogen atoms and one oxygen atom, and so its mass will be 2+16=18 amu . There are two water molecules formed, and that means the total mass of the products is 18⋅2=36 amu .
<u>Answer:</u> The equilibrium constant for the reaction is 54.47
<u>Explanation:</u>
The equilibrium constant is defined as the ratio of the concentration of products to the concentration of reactants raised to the power of the stoichiometric coefficient of each. It is represented by the term 
The given chemical equation follows:
The expression for equilibrium constant will be:
![K_{eq}=\frac{[HI]^2}{[H_2][I_2]}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5BHI%5D%5E2%7D%7B%5BH_2%5D%5BI_2%5D%7D)
We are given:
![[HI]_{eq}=1.3544\times 10^{-2}M](https://tex.z-dn.net/?f=%5BHI%5D_%7Beq%7D%3D1.3544%5Ctimes%2010%5E%7B-2%7DM)
![[H_2]_{eq}=4.5647\times 10^{-3}M](https://tex.z-dn.net/?f=%5BH_2%5D_%7Beq%7D%3D4.5647%5Ctimes%2010%5E%7B-3%7DM)
![[I_2]_{eq}=7.378\times 10^{-4}M](https://tex.z-dn.net/?f=%5BI_2%5D_%7Beq%7D%3D7.378%5Ctimes%2010%5E%7B-4%7DM)
Putting values in above expression, we get:
Hence, the equilibrium constant for the reaction is 54.47
Answer:
0.91 g NaF
Explanation:
Mass percentage is one way of representing the concentration of an element in a compound or a component in a mixture. Mass percentage is calculated as the mass of a component divided by the total mass of the mixture, multiplied by 100%.
Let mass of NaF = x g
∴ mass percent = mass of NaF / mass of total mixture *100
3.5 = (x/ x + 25) * 100
∴ x = 0.91 g
Answer:
what? that's 66 total, 6 more elliptical machines, a 1 to 1.2 ratio
but I don't know what else you would mean
Based on its location on the periodic table, the metal that is likely to be less reactive than both strontium and sodium is <span>magnesium (Mg). The answer is letter A. The rest of the answers are highly reactive.</span>
