A. Its temperature will rise continuously until it completely melts
I don't believe that any of the other answers are correct because the ice cannot stay at a certain temperature if it is melting.
The
balanced reaction would be written as:
<span>
C7H6O3 + C4H6O3--->C9H8O4 + HC2H3O2
To determine the percent yield, we need to first
determine the theoretical yield if the reaction were to proceed completely.
Then, we divide the actual yield that is given to the theoretical yield times
100 percent. The limiting reactant from the reaction would be salicylic acid.
We do as follows:
<span>Theoretical yield: 50.05 g C7H6O3 ( 1 mol /
138.21 g ) ( 1 mol C9H8O4 / 1 mol C7H6O3 ) ( 180.157 g / mol ) = 65.24 g C9H8O4 should be produced
Percent yield = 55.45 / 65.24 x 100 = 84.99%
<span>
Therefore, the percent yield for the given amount of salicylic acid is 84.99%

Answer:
it's atomic number reveals it's amount of electrons, each shell have a certain amount it could carry it's
2-8-8-18-18-32-32
It's called the octet rule.
True. Cs is metal, Cl is nonmetal, the difference in electronegativities is high enough to form ionic bond.
Answer:
Explanation:
Let suppose that air inside the tire behaves ideally. The equation of state for ideal gases is:
As tire can be modelled as a closed and rigid container, there are no changes in volume and number of moles. Hence, the following relationship is constructed:
The final pressure is:
