Answer:
c. 131 kPa
Explanation:
Hello!
In this case, since the relationship between volume and pressure is inversely proportional, based on the Boyle's law:
Considering that the standard pressure is 101.325 kPa, we can compute the final pressure as shown below:
Therefore, the answer is c. 131 kPa
.
Best regards!!
the complete question in attached figure
Let
x------------------- > actual yield
y------------------- > theoretical yield
z------------------- > percent yield
we have that
z=x/y
we know
x=47 g
y=56 g
therefore
z=47/56=0.839 ---------------- > 83.9%
the answer is the option C 83.9%
Answer:
i believe it is titanium.
Explanation:
Iron bending is just a physical change because the iron has only changed shape but there is no new substance. Iron rusting is a chemical change because there is a new substance which is rust.
Answer:C
Explanation:
A process is called spontaneous if the process takes place on its own without the intervention of external factors.
The spontaneous processes are generally quick with observable rates of reaction.But processes can be spontaneous even with negligible rates of reaction.
Spontaneity of reactions depend on temperature.
This is because spontaneity is measured by gibbs energy or enthalpy.
Both of these measures are dependent on temperature.
So,temperature affects spontaneity.
