Alright love it would be --- B. Neutron
<u>Answer:</u> The standard enthalpy change of the reaction is 358.1 kJ
<u>Explanation:</u>
Enthalpy change is defined as the difference in enthalpies of all the product and the reactants each multiplied with their respective number of moles.
The equation used to calculate enthalpy change is of a reaction is:
For the given chemical reaction:
The equation for the enthalpy change of the above reaction is:
We are given:
Putting values in above equation, we get:
Hence, the standard enthalpy change of the reaction is 358.1 kJ
Answer:
C- A solution of salt water
Explanation:
You cannot see the salt within the water, for it has already dissolved. The contents are uniformly distributed throughout the water's volume.
I hope this made sense! (^-^)
Answer:
Explanation:
Hello,
In this case, the first step is to compute the moles of carbon in the sample that are contained in CO2 only at the products as shown below:
Next the moles of hydrogen contained in the H2O only:
Now, we compute the mass of oxygen in the sample, by subtracting mass of both carbon and hydrogen from the 3.626 g of sample:
And the moles:
Now, the mole ratios by considering the moles of oxygen as the smallest:
Thus, empirical formula is:
Regards.
1 mole --------- 22.4 ( at STP )
2.66 moles ---- ?
V = 2. 66 * 22.4 / 1
V = 59.584 / 1
V = 59.584 L
hope this helps!
