<u>Answer:</u> The moles of given hydrocarbon is 0.3 moles
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
We are given:
Given mass of ethane = 10.0 g
Molar mass of ethane = ![[(2\times 12)+(6\times 1)]=30g/mol](https://tex.z-dn.net/?f=%5B%282%5Ctimes%2012%29%2B%286%5Ctimes%201%29%5D%3D30g%2Fmol)
We need to divide the given value by the molar mass.
Putting values in above equation, we get:
In case of multiplication and division, the number of significant digits is taken from the value which has least precise significant digits. Here, the least precise number of significant digits are 1.
Hence, the moles of given hydrocarbon is 0.3 moles
Answer:
According to Le Chatelier's principle, adding additional reactant to a system will shift the equilibrium to the right, towards the side of the products. By the same logic, reducing the concentration of any product will also shift equilibrium to the right.
Explanation:
Answer:
Explanation:
Here, we want to write the chemical reaction
step 1:
we start by writing the reaction between iron and oxygen
We have this as:
step 2:
Now, we want to predict the product as follows:
step 3:
We proceed to balance the chemical reaction as follows by ensuring that the number of elements moles on the reactant side is equal to the number of moles of the elements on the products side as follows:
