What is the temperature if 2L of 3moles HCl react with 2atm?
1 answer:
Answer:
Explanation:
Hello!
In this case, according to the gas laws, we would be able to assume HCl can be modeled as an ideal gas for this calculation purpose; in such a way, we use the following equation to compute the temperature:
In such a way, we plug in moles, volume and pressure to obtain:

Answer:
Option C, (Actual yield ÷ percent yield) × 100
Explanation:
Theoretical yield is defined as the total amount of product formed for given reactants in a chemical reaction. It is an ideal case which assumes no exceptions or wastage.
The mathematical relation between the actual yield, percent yield and theoretical yield is as follows -
Where
P.Y. represents the percent yield a
M A.Y. represents the mass obtained from actual yield
M T.Y. represents the mass obtained from theoretical yield
Hence, if we rearrange the formula, we get -
Hence, option C is correct
Answer:
77,007 Pa
Explanation:
Hello!
In this case, since the equivalence statement for atmospheres and pascals is:
1 atm = 101,325 Pa
We can set up the following conversion factor to obtain the pressure in pascals:
