D. The particles are tightly packed together
Answer:
64g of Oxygen
Explanation:
Firstly, carbon and oxygen react to form CO2 as follows;
C + O2 => CO2
According to the equation, one mole of C reacts with one mole of O2 to give one mole of CO2
Since molar mass of C= 12g/mol, O= 16g/mol
One mole of (C) contains 12g
One mole of O2 contains 16(2) = 32g
Hence, If there are 24g of C, there would be 24 × 32 / 12
= 768/12
= 64g
Hence, there would be 64g of oxygen if there are 24g of Carbon
C because neither the water or salt have changed their molecular structure. H2O is still H2O and NaCl is still NaCl.
Answer:
wavelength = 1.71× 10⁻⁶ m
Explanation:
Given data:
Wavelength of wave = ?
Frequency of wave = 1.75×10¹⁴ s⁻¹
Solution:
Formula:
Speed of light = wavelength × frequency
wavelength = Speed of light / frequency
Now we will put the values in formula.
wavelength = 3 × 10⁸ m/s / 1.75×10¹⁴ s⁻¹
wavelength = 1.71× 10⁻⁶ m
<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
